Input:
Question: Input rating of this device is 1.2 A. Standard iPhone charger output rating is 1.0 A. Will it charge with this charger, or do I need higher output?
Document: Even using my iPad 3rd gen charger, capable of charging at a 2.1A rate, the current draw was only 0.73A. I suspect the charging IC is just a linear lipo regulator so the charge current to the 18650 cells is 1:1 for the input current. If true, and if one goes by the advertised mAH rating of 11200, then at 0.73A charge, full charge takes 15.5 hours.
I would buy another, charges at A.C. speed. charges my battery about ten times. It is great for emergencies and long car rides. the device is built in all aluminum. I had a problem with one of the usb cables that came with it. But I had the original cord for my device, so i didn't need it.
Bought this for a long flight. To recharge iPad if needed. This battery charges your iPad 1 time, it's very quick and reaches a 100%. It charges iPhone more then 4 times. Only thing you need to calculate is that this battery takes a long time to charge, about 15 hours. Not a big deal, but good to know.
I haven't measure the output (there is a reviewer on Amazon that has), but just by seeing how many times I can charge my tablet and phone with it and their batteries capacities, I'd say it's slightly below the advertised 11200 mAh.BUT, it's wicked fast. It's almost as fast as a wall charger. It charges my phone 2 times and my tablets 2 times over on a single charge. So I'm pretty please regardless of the actual output. For $20, you can't go wrong with this.
I have recharged my ipad about 50% more within an 1 hour or 2 also but it will drain it completely.Flashlight is VERY bright.Charger is pretty heavy and quite bulky. Not something you would want to keep in your pocket or purse too often because of it's weight - that is one con that I don't have it with me much. it's just so stinking heavy. But that is a trade off for having a battery pack with more power.... Overall I'm happy with my purchase.
Used for about a month now. So far we love it. It does take a good 6 hours to recharge completely when I plug it via usb cord into my computer. For some reason I am not able to plug it into my iphone charger block and plug it into the wall like some of my other external battery packs... Anyways, I am able to recharge my iphone in probably 1.5 hours I think.
I saw some other reviews where they measured their output current during the charge. I haven't measured it but I do know that nothing works on it when it is charging. I've tried every USB device I have, short of a USB lamp, and nothing works. As soon as I pull the plug, bingo. Things light up. Plug it in and power is cut.
Ok, who carries a Blackberry nowadays? Well, I carry one for work. For the price, this isn't too bad. It will charge my Samsung Galaxy S3 2-3 times. It will only charge my IPad (from 0%) up to about 50-60%. However, it is just a back up power supply, right.
Great battery. I have a Mophie that cost over $50 which dies after charging an iPhone once. This thing can charge an iPhone from 0-100 and an HTC M8 from 0-100 and still have juice left.
I ordered this battery pack on Friday, July 4th and received it on SUNDAY, July 6 - incredibly fast. Product itself looks and feels great. I've charged my iPhone 5 twice from ~20% to 100%. It charges just as fast as the Apple wall charger. After 2 charges, there's still 80%+ remaining (based on the unit's LED status).Very glad I waited to buy a portable battery pack and very glad I didn't buy from Fry's Electronics.
