RAVPower safe to use

Don't know if everyone has been keeping up, but there's a Google engineer who's been reviewing USB-C cables and accessories to see what's compatible and made to spec. If it's not engineered correctly, there's risk of damage to the charger and/or device. He did make a post on the RAVPower external battery:

I had already purchased the bank with the discount a few days ago; I'm just relieved to hear that they've done a good job with it!
[Nexus 6P Accessories] RED ZMAN:
This battery pack is insane. I wish the mesh case for it was a bit bigger, you know, to FIT THE BATTERY in. LOL

I haven't charged it since it showed up, and I still haven't fully killed it yet. It has charged 3 different LG G3's at 8 or 9 different occasions, and still has one light lit on it.
[Nexus 6P Accessories] ylexot:
I can fit the battery in the mesh case. I even have the two cables that came with it in there. But yes, it is a tight fit.
[Nexus 6P Accessories] RED ZMAN:
I was just teasing. I've got it "in" the case, a retractable and regular micro USB cable in on the side too. I'm just used to my now lost Anker bag, it cinched up around the end.
[Nexus 6P Accessories] FayezZ:
For those that own the RAVPower battery pack:

1. Does your 6P charge rapidly if you use the very short type A to type C cable that comes with the 6P?

2. Are you able to charge the battery pack itself (rapidly?) using the 6P's type C charger (i.e. via the type C port on the battery pack itself)?

3. Not seeing the promo code on RAVPower's site - can anyone point me in the right direction?

Thanks in advance.
[Nexus 6P Accessories] jTink010:
The sale ended on 10/30.
[Nexus 6P Accessories] RED ZMAN:
I finally killed my battery today. Took what, a week? Now for the first charge...

Nice though, it actually will charge your phone while charging the battery through it.
[Nexus 6P Accessories] rufflez2010:
It will (likely) charge rapidly. I don't get my Nexus 6P on Monday. Max is 2.4A at 5V through the QuickCharge Type A port.

It supports 3A @5V bidirectional. Their 5 Hour claim is throguh the MicroUSB port and a QuickCharge 2.0 charger. It probably wouldn't take much longer if any through the 15W charger that comes with the N6P

Gone
[Nexus 6P Accessories] kellybrf:
1- 6p coming in Monday, I'll try it but from what I've seen that cable isn't very good for charging

2- it charges at 3a/15w via type c, so it the charger can output that the battery pack will accept it. worked well with my 5x charger

3- sorry, can't help here

just received mine today, initial impressions are really good. well built, sleeve is nice and I like that the included cables are both flat and of varying sizes. I'm on a trip this weekend and will be using using this as my primary charger for my phone and watch in lieu of a wall charger.
[Nexus 6P Accessories] rdoane:
1. No. It does not register as charging rapidly. It does however charge fairly quickly. As you would expect, the USB type-c port does register as charging rapidly.

Below are some Ampere readouts on the various ports. Keep in mind my phone had about 85% when I took these so the important thing here is the relationship between the numbers. If I remember I'll try to capture the full charging rate for all three ports tonight when my phone is near dead.

USB Type-C (with the type-c to type-c cable that came with the 6P):

Quick Charge 2.0 (with the type-c to type-a cable that came with the 6p):

iSmart (with the type-c to type-a cable that came with the 6p):

2. Yes

3. The code is done, but it is still only $47.99 on Amazon with Prime shipping.

Also, another tip for everyone, if you register your device with ravpower.com they will extend the warranty to 18 months. Really easy and takes seconds.
[Nexus 6P Accessories] FayezZ:
Thanks for the replies, everyone. Follow-up question: will it simultaneously charge itself and another device connected to it? Example: plug in the 6P charger (C to C) to charge the battery pack and plug in the 6P (A to C) to charge the phone from the pack?
[Nexus 6P Accessories] jTink010:
Has anyone found a short type c to type c cable that is around 6" or so? I'd like to stick one in the pouch alongside the short A to micro B cable that came with it.
[Nexus 6P Accessories] rufflez2010:
Yes, at least through the micro slot, but Probably through the type-c port as well since its bi-directional. You could use a regular micro usb + type-c cable and be good to go if you have some of those laying around... who are we kidding, of course you do... probably like 20 of them.
[Nexus 6P Accessories] kgeissler:
I got my battery pack in the mail today. When my 6p drains the battery a bit, I will hook it up to the USB-C port and see what rate it charges at.
[Nexus 6P Accessories] kgeissler:
Here is what I observed. My 6P was at about 80% battery and I plugged it into the stock charger. According to GSam, it was pulling around 2300-2500mA. When I plugged it into the USB-C port on the battery pack, my Nexus pulled about 1700-1800mA. In both the QC and USB-A port, the Nexus pulled about 1500mA. My results are not scientific by any means, so take it with a grain of salt. I will try again when my battery level is significantly lower. When I was plugged into the USB-C port on the battery pack, the 6P did say it was charging rapidly.
[Nexus 6P Accessories] namz:
Bloody hell , how do u get this to Australia / India . I NEED IT !!!!!
[Nexus 6P Accessories] kellybrf:
ive had mine about a week now and i love it! full disclosure, ravpower sent me one in exchange for an honest review. the type c port can be used for both input and output, and delivers a full 5v/3a charge for the nexus 5x and 6p. ampere tells me this maxed out at 2590 mAh, the 5x charger at 2660 and the 6p at 2700 so all basically the same. testing was done with the battery around 12-14%. i used this for a weekend trip last weekend to charge my n6 and zenwatch, as well as the zero lemon battery case for the n6. it charged the phone and watch fully each night, plus top the phone off several times throughout the day. i also used it to fully charge the battery case once. i was gone fri-sun, and when i got home the bank had half of its power left. it was great being able to use this instead of having to look for an ill-placed outlet, this will definitely accompany me on any trips i go on in the future. i like that it can be quick charged with either a qc 2.0 or usb c charger as well. my only minor gripe is that it didnt come with a usb c cable (just two flat microusb cables, one short and one longer) but i cant really complain about that too much given the lack of usb c devices out there right now. overall this is a great battery bank that will give you many, many recharges.
[Nexus 6P Accessories] sabesh:
Stupid question, as I can't find the answer on the guide:

How can I tell when this is fully charged? I'm using the cable and adapter that came with my 6P (USB-C to USB-C). Thx.
[Nexus 6P Accessories] dadoc04:
I've been debating about this thing for about 10 days now... looks great but i been holding out just in case a better option surfaces in the near future...i may just say f it and buy this though tho
[Nexus 6P Accessories] Pilz:
I would say buy it. Considering its only $47 for a 20100mah battery with all of those ports it seems to be a good deal. I bought one and will let you know how it is. I have some Aukey QC2.0 battery packs and they were ~$22 for the 10000mah one and $27 for the 12000mah one. Ravpower seems to make some good things so we will see how it goes.
[Nexus 6P Accessories] dadoc04:
yea that's true... i used this one on my N6 and loved it https://www.amazon.com/dp/B00UBDI7EC/

when did u order the ravpower?
[Nexus 6P Accessories] sabesh:
I ordered and received this today. Amazon Canada has same day delivery for $7.00.
[Nexus 6P Accessories] itch808:
If they brought back the coupon I'd definitely jump on it. Otherwise, I'll just wait. These things will be dirt cheap before we know it.
[Nexus 6P Accessories] gqukyo:
I'm surprised nobody brought this up. It recharges via micro USB so wouldn't that mean it'll take forever to recharge? Probably not a problem for most since I think most would charge it overnight but I think I'll wait til one comes with a USB C input to recharge to take advantage of the increased charging rate.
[Nexus 6P Accessories] dadoc04:
that was pretty much my thinking too.
[Nexus 6P Accessories] Pilz:
I ordered it today so it won't be here until Tuesday
[Nexus 6P Accessories] dadoc04:
ill hold off at least until your review. thanks man
[Nexus 6P Accessories] Pilz:
No problem I'll try to post it when I get it, but i can't promise it will be up before Friday since i have an exam this week and a project/presentation due.
[Nexus 6P Accessories] dadoc04:
good luck with your exam and I'm fine with friday. The longer you take, the easier it will be to hold off lmao
[Nexus 6P Accessories] Pilz:
Thank you, it's the last one i have before finals and unfortunately it's also the hardest class. (It's a mix of thermodynamics, chemistry, matrices etc...) I'll be sure to test the battery during that time because i bought it so I could use/abuse and not have to carry my charger as a backup
[Nexus 6P Accessories] subhani:
See this post right above yours.

It recharges AND charges through the SAME type C port.
[Nexus 6P Accessories] NCguy:
The way the charge algorithm works they only charge at full rate up to around 80% and then all lithium chargers basically trickle the last 20%, especially the last 10%. This reduces heat gain to a minimum since the last 20% of the charge is when the batteries are sensitive to heating up.
[Nexus 6P Accessories] teknomar7:
The lights on the unit shut off. While charging, they blink to show which level it's at, then stop doing that and shut off completely when fully charged.
[Nexus 6P Accessories] undeadadd:
I'm on the verge of buying this, do you charge nexus 5x and 6p through the USB C port?
[Nexus 6P Accessories] gqukyo:
Not really right above mine but thanks for linking it. Lol
[Nexus 6P Accessories] Pilz:
You can or you can use an inspec type a to c cable
[Nexus 6P Accessories] undeadadd:
Will those cables charge the phones the same way the provided plugs and cables do?
[Nexus 6P Accessories] Pilz:
I have one and if you mean the same speed then no, at least my iroange one doesn't when I pair of with my 5V 4A charger. I don't have three battery pack yet but only the C-C will give you 3A from the battery. I also tried the small cable that came with my 6P on that wall charger I have and if won't hit 3A either.
[Nexus 6P Accessories] peeweehernan:
I forgot to charge my phone over night the other day so I took my RavPower charger to work with me. I think it charges plenty fast so I'm satisfied with it!

One of my coworkers calls it a bomb charger. I need to tell him to stop calling it that in front of others ?
[Nexus 6P Accessories] onilink67:
Agreed this will help greatly, but doesn't stop the physical loss of going through a cable and a few connectors. Increasing current through this will in turn increase heat (however minimal) just through the power transfer to the device, this can especially be seen in cheap thin cables that get hot to the touch (just due to a lower gauge not due to any extra power being transfered). I don't know if you read my follow-up posts this is more for someone like myself that goes off the grid for a week at a time a few times a year and needs to make his battery pack last as long as is physically possible so I can take pictures and make emergency calls if something happens and I can somehow get back into service range. I'm sure for someone that it almost always near a power source once every 48 hours or so this will be a null point for.
[Nexus 6P Accessories] sitnlow4life:
Just received my RAVPower charger today , it does rapid charge as promised , but it is way to big to carry around in your pocket .

I am coming from carrying around an Anker Astro Slim 3 which was very reasonable in size and easy to keep in your jacket or pant pocket.

Any suggestions on something smaller in size that will allow rapid charging ?

Thanks
[Nexus 6P Accessories] subhani:
My concerns exactly. It's way too big to be as convenient as the smaller ones. I know you sacrifice capacity but I only need it to charge my device when I'm short on power and away from a wall plug. So maybe two or three charges MAXIMUM and that's exaggerating it. A minimum of one full quick charge is my minimum criteria. Plus mobility of course.
[Nexus 6P Accessories] onebelo:
yea im hoping Anker will come out with some soon. Since they got some nice slim ones currently. something in the 10,000mah range would be perfect while being small/slim.
[Nexus 6P Accessories] sitnlow4life:
I agree 100% I guess I will send this back for now

I need to find a car charger that can rapid charge to hold me over
[Nexus 6P Accessories] Pilz:
It is really big, but its worth it for traveling. I don't want a tiny battery with no capacity but I don't want it to be gigantic. This is a compromise for me and worth it until better options are released
[Nexus 6P Accessories] 911jason:
Yep, me too... Unless they want to send me a free one for review! ;)
[Nexus 6P Accessories] pdubcramp:
Anyone know why the ravpower isn't listed on Amazon anymore?
[Nexus 6P Accessories] subhani:
I just bought it from Amazon UK day before yesterday. I can't believe I pulled the trigger on this. Mostly because I'm going travelling before the new year. I have to be honest, it's not providing the 3A I was looking for.

Sent from my Nexus 6P
[Nexus 6P Accessories] pdubcramp:
Strange that it's available in the UK but not the US. Even more strange that they aren't in stock during the holiday push. Either they couldn't keep up with the demand of being the only compliant external battery or there is some issue? Odd
[Nexus 6P Accessories] andy o:
I tested some charging speeds with 3 different chargers, with some interesting results. With the Nexus 6 charger and cable (QC 2.0) USB power monitor read was about 12V and just a tiny bit above 1A (around 12W), and charging from depleted to full takes about 9 1/2 hours.

With the Google Type C charger, charging took about 7 1/2 hours.

The interesting thing: with the Choetech single-port QC 2.0 charger, the USB monitor readings were about 19W (at just above 10V)! Charging took only 5 1/2 hours.
[Nexus 6P Accessories] kalookakoo:
They told me they it's an "issue" they are trying to resolve by amazon, and their listing was blocked.
[Nexus 6P Accessories] keljai:
i saw choetech had a usb c external battery, but not sure of the brand, anyone can comment?
[Nexus 6P Accessories] DeathmonkeyGTX:
I got the ravpower type C external battery, it came in over a week ago. It works fine, what issue might it have? Hardware defect or some listing error or Amazon being factitious or...?
[Nexus 6P Accessories] pdubcramp:
I don't think there is any reason to jump to the conclusion it's defective but knowing how Amazon operates, I'd think they could fix a listing in minutes, not multiple days. I have no experience as a retailer with Amazon, so I could be completely misguided.
[Nexus 6P Accessories] Pilz:
Mine has started to lose capacity so it seems. I fully charged my 6P from 20% to 100% 2 time using the pack recently. The battery was at 100% when I used it to charge my 6P but after those 2 ~80% charges on my 6P the RavPower dropped to 1 led light out of the 4 it normally has when full. Now let's do the math to see what capacity would have been used charging the 6P: 3480mah * .80 = 2784mah for the dull charge. 2*2784=5568mah. I will assume a efficiency of 70% from the battery which would give a total of 9465.6mah used while charging the phone. The battery pack has a capacity of 20100mah which should leave 10634.4mah left over or 2 led lights reflecting the half dead battery pack now. The issue is that the battery pack is only showing 1 light and after seeing this happen earlier it will likely not charge NY phone again fully. I'm not sure why there is such a large loss of power in the pack, but the issue is certainly concerning to me after only having Jr for a few weeks.
[Nexus 6P Accessories] instadroid:
same, annoying:rolleyes:
[Nexus 6P Accessories] aw1974:
Mine is doing the exact same thing. 2 full charge cycles and it's down to one light. I'm going to try to get a warranty replacement.
[Nexus 6P Accessories] Pilz:
Mine took a while (~7 charge cycles) before this started to happen. I'm getting close to the end of my return window, and I figure if the new one has issues I will be stuck with it. I'm sending it back because of the time frame, but I hope another viable option comes out soon.
[Nexus 6P Accessories] dadoc04:
welp same here... gonna be returning.
[Nexus 6P Accessories] RED ZMAN:
Haven't used mine much but I'll abuse it over the weekend to see if I'm in the same boat. Did anyone try the MonoPrice.com one I posted a few days ago?
[Nexus 6P Accessories] kellybrf:
they reached out to me today to check in and I mentioned the capacity issues some of you were having. she advised you all to email ravpower@support.com and she said they would look into what is going on.
[Nexus 6P Accessories] subhani:
Is it possible to share this thread link to them? If you ain't already done so. Cheers.
[Nexus 6P Accessories] aw1974:
Anybody else contact Ravpower? This is the reply I got.

Thank you for contacting with us.

The voltage of the battery cells is 3.7V, however, the output voltage of the power bank is 5V. You must allow wastage when the voltage increases. And in the market, the average efficient of the power bank is about 75%.

So the actual capacity of the power bank should be:

Labeled capacity *3.7V /5V * Efficient = 20100*3.7/5*75% =11155.5mAh

*

As your phone*is with the battery of*3450mAh*, it can only be charged for 11155.5/3450=3*times.

Could you please make sure that you have fully charged the power bank?

Please try to fully charge it then change another cable to test if the same problem exists?

Please do not worry about it. We will give you a good solution once we assure the problem.

If you have any further questions or concerns, please do not *hesitate to contact us.
[Nexus 6P Accessories] Pilz:
I was close by guessing a 70% efficiency then :) I don't understand why external battery packs aren't made in a way that would allow them to deliver more of the power to phones instead of losing such a large amount due to the inefficiencies of the system. A 80% efficiency would be nice, but that appears to be too much to as for.
[Nexus 6P Accessories] aw1974:
I guess I'm a bit surprised at they're claiming 75% efficiency after the voltage increase of the cells and output. Even if that is the case I'm only getting about 2.25 charges on my 6p when they're claiming I should get 3+. I still think there could be an issue here. I will try what they recommended and even try the lower output ports as well.
[Nexus 6P Accessories] desean:
The Amazon link is back online again. http://www.amazon.com/gp/product/B0156HCJQO
[Nexus 6P Accessories] Gorgtech:
Now let´s do some math. If this unit uses a 20100mAh battery inside at a voltage of about 3,7V, we could expect in theory a power of about 74,37W. Since every battery pack uses a circuit to convert the 3,7V up to 5V ( through a step up convertert ) with a efficiency of about 75%, you should obtain a "real" usable capacity of about 11156mAh.

11156mAh / 3450mAh = 3,23x

You should be able to charge a Nexus 6p about 3x times if everything is ok. Maybe the cells used in this battery pack have large tolerances ?
[Nexus 6P Accessories] Trueglich:
Not sure about that. I am just about to RMA my rav power due to louse ports and i desired to try to run it down before shipping. I put my nearly dead nexus 9 on it and it when from 4 lights on charge meter to 1 by the time the tablet was charged nexus 9 has a 6700 battery so it may be closing to 2 and change for a 6p.
[Nexus 6P Accessories] Pilz:
I returned mine because it's a little misleading when you expect to get more out of such a large battery pack. I don't see why its not possible to have a higher base voltage in the battery pack; they could avoid such a high loss of power when it steps up the voltage.
[Nexus 6P Accessories] RED ZMAN:
I like mine, I find I barely have to use it ever compared to when I had my LG G3.

This does concern me though, for a battery this frigging big, it should charge more.

Has anyone done some testing to see if perhaps it is the 3A charging that has an issue by testing some of the other ports with other devices?
[Nexus 6P Accessories] dadoc04:
you find anything new or maintaining without the battery pack?
[Nexus 6P Accessories] Pilz:
I haven't seen any new ones worth buying as of right now, so I'm managing without one. I really don't need to charge my phone ever during the day it's more of a feel good thing to have as a backup
[Nexus 6P Accessories] kellybrf:
I got an email from them yesterday, they are sending me out a revised version. the main change is the upgrade to qc 3.0, I'll make sure to post a review when I put it through its paces
[Nexus 6P Accessories] RED ZMAN:
Any other noted changes? If they are upgrading it I may contact them too.
[Nexus 6P Accessories] hkhei:
I always wonder if it is the correct way to calculate the efficiency.

Let's say the external battery supports QC3.0 which provide a 20V output. The "real" usable capacity would be 3.7/20 *0.75 = 2788mAh @20V.
[Nexus 6P Accessories] Gorgtech:
It is a close approximation if we consider the input power = output power for the calculations. But you need to consider the fact that we have losses and most the time, step up converters work at a efficiency of about 75%. In theory, this method is good enough to have a good guess about what to expect from a battery pack. Now on the other hand, even the cells used have tolerances.
[Nexus 6P Accessories] kellybrf:
they didn't mention anything notable beyond that
[Nexus 6P Accessories] etreuz:
How

How do you get the discount code? You are in the super user program or something? Let me know how you get it please.

Thank you..
[Nexus 6P Accessories] dadoc04:
that was only for the first 100 units i believed. Deal is done with now.
[Nexus 6P Accessories] a.gu:
I'm sure that as the competition develops, we'll get some better prices soon. We just have to wait for a little while. normal external batteries are in the $20-30 price range nowadays, so it'll just take a little time.
[Nexus 6P Accessories] subhani:
I just wanted to say that I came from the 32c3 CCC conference in Hamburg a couple weeks ago and I solely used this external bank for my 6P and occasionally for a mate's Z3.

1. The pack is just too big and impractical. Better to carry the charger and find a socket when desperate. I understand the advantage and freedom of charging whenever and wherever you like without a wall socket but at this size and wait, it was not a significant enough return for the trouble. Besides, the 6P battery life really is quite reliable so if you know you gonna be away from a wall socket, being thrifty with usage always leaves enough in the 6P's tank.

I just wish there was a middle ground here. A smaller more pocket friendly compromise.

2. It charges really well. Still slower than the wall charger, even when using Google supplied CtoC cable. But still respectable. Gave me only about 4 and a half full charges though. Was expecting more considering its capacity. I only charged the bank twice to full also.
[Nexus 6P Accessories] lanternca:
Totally agree. It bothers me to have to carry a big battery pack when I really want a small slim one to get me through the day, or maybe an overnight trip.

What would be perfect is something with a built in cable (or at least a built in micro usb cable with a storage spot for a type c adapter). Like this, but not a lightning adapter.

Anyone seen anything?
