Totally agree, though something which could run off disposables has a bit of appeal also - if only for those 9+ hour flights... so in the gogol spirit of "try 'em all" I went ahead and ordered the boxwave unit - should arrive in a week or so and will report here :)

[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
If you're after a disposable battery solution (or presumably a rechargeable AA battery solution - though I've not tested that mode), then the Boxwave looks like a viable choice!

http://www.boxwave.com/products/batteryadapter/index.htm

I repeated the same test as with the APC: ran Kaiser down to 48% and began charging with phone in standby mode, but doing direct push on 3G.

After 1hr it was up to 57%.

After 2hrs up to 71%.

Then I went to sleep :(

The next morning the phone was still running on external power and sitting happily at 100%!

The Boxwave unit has no on/off switch, no battery meter, and no provision for charging - should you choose to use rechargeable batteries. For that matter it comes with no instructions. It's about the same size as the Kaiser in all dimensions, and finished with a nice soft-touch surface much like the Kaiser battery door. The sticker on the bottom of the unit says:

Input: 4x AA Batteries

Output: 5.2V / 800mA

I've not tested the unit with the Kaiser running, for some reason I have my doubts about that 800mA number - but some experimentation might convince me otherwise. (Ok, while I was typing I was running the Kaiser off the battery pack and the power light went out - so one set of fairly cheap AA batteries might be good only for this much recharge. Turning the Kaiser back off puts the charge light back on - so either the batteries are too dead to provide that much current or this unit isn't able to do so.)

Given the much lower price, and ability to use standard AA batteries, I can see this unit being attractive for some people. Personally I much prefer the APC battery for it's recharge capability, battery meter, and more compact size. If you intend to carry rechargeable AA batteries and a charger anyway then this could be a viable solution.
[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
I just measured the disposables at 1.27V each, so they were definitely nearing the end of their life by this point.

I went ahead a threw in a set of 1600mAh NiMHs that I'd charged up the other day - just to see if rechargeables work at all - and whether they'd be able to run the Kaiser and charge it simultaneously.

Richard
[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
Fresh NiMHs did charge the running but idle Kaiser up from 92% to 100% sometime during the last half hour or so.

Richard
[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
Ran phone down to 56% or so, tossed on the charger overnight and it got only up to about 76% :( :( :(

I think the Boxwave unit has only a voltage regulator and not a charge pump - so NiCd or NiMH batteries aren't very useful. (4x1.2V nominal charged voltage is barely enough to charge a 5V device - vs 4x1.6V nomial charged voltage on alkalines.)

I'm changing my recommendation on this unit to "Buy only as an emergency charger or if you have an unlimited supply of Alkaline batteries." :(

iGo powerXtender™ battery operated charger

My iGo powerXtender works wonders. It uses 2 AA batteries and has exchangeable tips for charging other devices without having to carry the devices cables around (I HATE cables). I use Sony rechargeable Ni-MH batteries that are rated at 2700mAh each (website states 2500mAh, but label on battery says 2700mAh). These batteries charge in about 4-8 hours in their charger.

I like this more than the APC charger since I can just throw in fresh batteries at any time and not have to recharge my charger. This comes in handy on 12 or 13 hour flights or camping trips. It also has an on/off switch with a power on indicator.

I just did a test with 25% battery power remaining on my Tilt, and here are the stats:

8:25am - 25%

9:25am - 49-50% (1 hour later)

9:40am - 55% (15 minutes later)

9:55am - 60% (15 minutes later)

10:31am - 66% (36 minutes later)

10:41am - 100% (what?!)

Now, I have no idea how my Tilt charged 34% in the last 10 minutes of the test, but thats what it said! I even did a soft reset to make sure. I will have to retest again later tonight and repost. I just wanted to share this info with you guys right now.
[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
Interesting - definitely looking forward to your retest data! Would also be interested in a review run with disposable Alkalines if you could. I think a number of these charge-pump type devices may work much better with rechargeables than with disposables due to their higher current capability.

Thanks!

I'm a big fan of the Power Monkey

[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
Can you post some Kaiser charge times? The specs look a lot like the Keomo, and Newegg has it priced about the same as the APC. My guess is it performs like the Keomo, which coupled with needing a custom charger would make it undesirable in my opinion - but I'd want to know how well it works before deciding.

Thanks,

Richard
[Tilt, TyTN II, MDA Vario III Accessories] Jim_R:
Help me understand here. Why get a power pack over a second battery? Seems to me that the purchase price of these packs is much higher than a second battery, charging time is as long or longer, the size and weight are much greater than a replacement battery, and from what I'm reading here, the power packs only partially recharge the stock battery - I don't get it. :confused:
[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
1) You can use it for more than just the device in question. My APC has run my Hermes and my Kaiser - I'd have been out the cost of multiple extra batteries and multiple external chargers as the two take different batteries.

2) You can work uninterrupted. Replacing the main battery requires rebooting the Kaiser.

3) If you compare to a no-name Chinese knockoff battery, sure, but not if you compare to an OEM battery.

4) If you want the equivalent functionality - i.e. can recharge both the main and the backup battery simultaneously, you have to buy an external charger for the backup battery - which adds cost and risk, as there are no OEM external chargers as far as I know. Worse, using only the Kaiser itself for charging both your main and backup batteries requires yet another device reboot as you switch them out again to recharge.

5) Neither the APC nor the Keomo is in practical terms *much* greater size/weight IMO. I'd want some kind of protective cover for the backup OEM battery to prevent shorts and mechanical damage - the external packs are already protected.

6) My tests of the APC suggest it could completely recharge the main battery at least while the unit is in standby mode.

7) You do raise an interesting point of trying to compare the runtime of a fully charged Kaiser + fully charged APC to the runtime of a fully charged Kaiser alone. I'm not sure when I could be without my device long enough to do a reasonable test on this. As mentioned before I recharged my Kaiser from some unknown level (85-90%?) to 100% and then read ebooks for at least a couple of hours or so plus watched 3hrs of MPEG4 video before fully exhausting my APC battery on a recent flight.

My gut feeling is that amount of usage would have more than exhausted a stock battery, so I suspect the APC has more capacity than a stock battery - so you need to compare the price of 1x APC to at least 2x stock batteries. Arguably 2x external chargers too.... that makes the $ uncompelling, and the amount of extra crap you're carrying around is highly unattractive vs the APC and a stock charger....

Has anyone tried this from The Pocket Solution? http://www.thepocketsolution.com/Me...een=PROD&Store_Code=PS&Product_Code=PSI-42555

From the description:

The AT&T Tilt Battery Extender is an ingenious device powered by 4AA batteries. Its proprietary technology draws a charge from the AA batteries and transfers it to your device, thus providing it with the electric power that is its required sustenance. Even if your device is 100% drained – stone cold device d-e-a-d – the AT&T Tilt Battery Extender can bring it back to life not once, not twice, but, in fact, 2.5 times. That’s right: You get two-and-a-half complete charges from one set of AA batteries. And it’s fast too: the Battery Extender takes your device from zero to 45% charged in just 20 minutes!
[Tilt, TyTN II, MDA Vario III Accessories] Jim_R:
Too funny! They seem to think that TILT owners have money to burn - do a search there under AT&T 8925 and the same product is only $12.95! :p

Also laughable is the fact that they have a version with the same charging claims that only requires 4 AAA's, for only $9.95! Amazing that they can get the same output from smaller batteries!!! (Not sure if they charge TILT owners $2 more for this one) :D

http://www.thepocketsolution.com/PSI-42763.html
[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
Yeah, 2.5 full charges is a pretty rediculous claim based on the numbers posted here! It's possible that with a charge pump they could extract a bit more power than the Boxwave unit does with just a regulator - but not THAT much more, IMO.

I won't be the guinea pig on this one! If someone else wishes to be, feel free. Almost as entertaining (and cheaper) would be to e-mail them and ask how they can get 2.5 full charges on a 1300mAh battery from batteries with <700mAh capacity (AAA).

Richard
[Tilt, TyTN II, MDA Vario III Accessories] met3ora:
I'm up to email them. Give me all the technical numbers and I'll craft an email!
[Tilt, TyTN II, MDA Vario III Accessories] rsolomon:
Here's a link to a set of AAA alkaline batteries which claims they're good for 1150mAh:

http://www.superwarehouse.com/Monster_Cables_AAA_Alkaline_Battery_(4_Pack)/MB_AAA_ALKA-4/p/718360

It's simple math:

4x1.5V = 6V

6V * 1150 mAh = 6900 mWh capacity in the 4 AAA batteries.

Kaiser Battery is rated 3.7V @ 1350mAh

3.7V * 1350 mAh = 4995 mWh capacity in the Kaiser battery.

6900 mWh / 4995 mWh = 1.38 times.

So even with 100% perfect energy conversion you'd get at MAXIMUM 1.38 Kaiser charges out of that pack. In real life, you're converting the 6V -> 5V (losing energy in the process) then the Kaiser converts 5V to ~4.2V to charge the battery (losing energy in the process), plus the actual charging is nowhere near 100% efficient, so even more energy is lost... I bet you can't even get ONE full Kaiser charge out of that pack.

I think no-name alkalines are more like 700mAh capacity, so unless you're using $$$$ batteries, you're even worse off.

Ask them if they have a perpetual motion machine on pre-Christmas sale too.

I'm astounded by how many of these devices are out there, and how FEW of them actually work at all.

Richard

P.S. The really interesting question would simply be "Does your battery pack use a voltage regulator or a charge pump? What is the maximum current output?"

The PocketPCTechs unit appears to use neither! It has a resistor to drop the 6V from alkalines down to 5V, and a switch to remove that for using NiCd/NiMHs (where the typical voltage is more like 1.2V vs 1.5V for alkalines).

The Boxwave unit appears to have a regulator, so it limits the 6V battery output to 5V, but NiCd/NiMHs work poorly because they drop below 4.5V too quickly and the output follows.

The APC and Keomo units have a charge pump which turns their battery's 3.7V into 5V.

A charge pump could run down to 1.xx volts and still produce 5V on the output, so it could extract a lot more energy from an alkaline than a regulator could, but it's a relatively expensive piece...an alkaline or NiCd/NiMH using pack with a charge pump would be ideal - but I've never seen one myself.

I might only give the company a B, because they SHOULD know the answer to how the charger works. I'm impressed she followed up with you, but I'd bet money the charger does NOT provide even one full Kaiser charge.

Ask if they'll refund your money including shipping both ways if it won't do the 2 charges on a Kaiser.... :D

Brando USB Solar Chargers

Brando sells a couple of USB chargers that might be of interest to this crowd.

2-USB-Ports Multi-Solar Charger

http://usb.brando.com.hk/prod_detail.php?prod_id=00314&dept_id=015&cat_id=035

Universal Solar Charger

http://usb.brando.com.hk/prod_detail.php?prod_id=00304&dept_id=015&cat_id=035

I have the 2 port version. I like the fact that the solar panel allows me to keep my kaiser juiced up even when I've forgotten to charge both my phone and the battery pack.

I don't have any statistics like the other chargers, but I'm not sure it would be a fair comparison since the solar panels give this charger a virtually unlimited power capacity. It may take a while though, since a full charge of the battery pack via the solar panels may take many hours of sunlight. I have used it many times to trickle charge my phone while in transit in a cab or flying in on a plane. On the plane I'll typically turn off my phone so it takes less power to charge the kaiser.
[Tilt, TyTN II, MDA Vario III Accessories] RemE:
Hi all, I thought I'd weigh in on this subject as I've been a long time portable video user while flying on trips. I have the APC, the Boxwave, and the Semsons "Power Bank" units.

1st Batteries, Lithiums are 3.7v per cell and packs like the APC have 2 cells in series with a regulator to 5V output. Lithiums don't need any cycling and when charged, they have a low self discharge meaning that they can sit for a while and still be ready to go. NickelMetalHydrides also don't really need cycling but have the worst self discharge so they really need to be charged just before travelling.

The APC unit really is an excellent unit. On my Kaiser I started with a charged battery and with the APC connected to it the Kaiser played video 7 1/2 hours straight. At that point the APC shuts down cleanly because the regulated output (measured at 5.2v) keeps the Kaiser full to the very end. The Kaiser's green charge light then goes out at which it's still at full charge and could run another 3+ hours if needed to watch another movie. For it's size, it's really nice, very sleek and light design, feels good to hold.

The Boxwave unit really is designed for 4 alkaline AA's, but suprisingly it does NOT have a regulator as I measured the output and it matched the battery's output (5.8v for the 4 I had in) . I put in four 2400ma NiHi's and it would power the kaiser for about 3-4 hours but the phone's charge light goes out fairly early because the voltage of 4 NiHi's starts at around 5.2 volts and drops from there so the phone stops charging. After 4-5 hours of use I found that the phone's power level had begun to drop so if the charge lite is out, the phone is beginning to discharge. In a pinch the Boxwave would be good though with Alkalines which can easily supply lots of power in situations where chargers were not available, plus it's a flashlight. But I do wonder if it's pushing the phone to give it almost 6V with fresh batteries. Nice "rubberized" finish like the Kaiser's back cover.

The last unit is the Semsons SEM-B003 Power Bank. It's bigger than the APC and Boxwave units, but, it is both power supply AND charger, with a flip out A/C Plug. It's designed for NiHi's and can cycle the batteries if desired with a switch on the back. I haven't had a chance to do the long run test, but I suspect that it will be the same as the Boxwave with the same limitations. When I get a chance I'll post the run time.

Edit - after about 8 days of non use, I found that the fully charged SEM-B003 pack had it's Red LED lit up indicating low battery. This means that you simply can't leave batteries in this unit when not in use.

After 22 days I just checked the APC's check button and it's LED gauge shows full bars so it's very good at sitting on the shelf in standby mode. My vote is for the APC battery, small, light, and long lasting.

Great APC customer service

I bought the APC unit about a month ago, and used it maybe 10 times. The other day, I was using it to charge my Tilt, and it stopped working. The top and bottom indicators lights only came on. Connecting to a charger changed nothing. I called the 800 number on the back of the unit yesterday afternoon, and described the problem. By noon today a complete new unit was delivered to my door. I strongly recommend the APC.

Another thought / question: Since there seems to be some risk with using AA battery solutions described in this thread to charge our phones, what about using AAs to somehow charge the APC, and then use the APC or the passthru function to charge the phone?
[Tilt, TyTN II, MDA Vario III Accessories] RemE:
I thought of that as well, but I'd just use the Boxwave directly, the voltage will pull down to the mid 5V range fairly quickly and is probably just fine with the phone. I carried both the APC and Boxwave on my last trip. With 2 legs and 15 hours of travel time each way I went thru 4 1/2 movies just using the APC. Never had to pull out the backup Boxwave.
[Tilt, TyTN II, MDA Vario III Accessories] axeman:
HI, i picked up this APC Unit, by mistake http://www.apc.com/resource/include/techspec_index.cfm?base_sku=PNOTEBX which needs 4 AAA batteries. I used 4 Energizer AAA 1.2v 900 ma batteries fully charged. It could only charge up a bit of my almost empty phone, but after that it seemed as if the charger was drawing back power from the phone (if thats possible) because the phone got hot and discharged faster than normal.

I am not sure if i should try this again, so will wait for commenst before going for it again.

With Kingroot you can uninstall bloatware and so kinguser normally...

Do a Google search for:

You'll have to flash the stock firmware if it is available to the public. Root the device again and then try using the Supersu-me app to convert to SuperSU.

If the stock firmware isn't available, try using adb to remove kingroot.
