CoolTech - iPhone Emergency Solution

How many times have you been without a much-needed recharging solution with your non-battery-swapable iPhone? For me, it is all to often, and I just can't risk losing a call because of a dead iPhone. So, friend and colleague, virginia corporate headshots photographer Mark Finkenstaedt had a solution. Mark did all the hard work doing this testing, and here are the results.

This battery, by ebay seller scr-boya (other listings here) lists the following features:

-Capacity:1900mAh
-100% Brand New
-Dimension:67mm X 62mm X 15mm
-Input:5V 0.8A
-Output: 5V 0.5A
-Charge time: About 4 hours
-Colour: Black only

At right is one of the four of mine that I won, on eBay, for $0.99 each, plus $8.99 shipping (each!) from China. So how long does it take for the battery charge to fully charge?



When the 10% battery warning indicator came on, the battery was installed, and below is the timeline for it to charge:

At $10 per unit (including shipping, and I tried getting more, but no response), I can justify buying several (which I did) and now I have a backup in my car, camera bag, and two rotating on chargers in the office. The seller shipped both to Mark and I (from China) without any problems, so if you're looking for a great solution, this one one gem that has already saved me from a dead iPhone battery. There are other sellers on eBay with variations on this item, so you might find others that work just as well, but so far so good with this seller!
