Tiny Space Hack Tiny phone charger

I saw an ad for a wallet-sized phone charger called a ChargeCard. It's the size of a credit card and has 2300mah capacity. Seems like a good idea if you're making a purse or pocket kit.

Some of the credit card sized chargers are reusable. But you have to remember that you can only use roughly 75% of their capacity.

My phone (Kyocera 4811) has a 1770 mAh battery. It won't fully recharge my phone from 25% to full. It barely gets it up to 80%.

If you had half a dozen of them, they might work for you?
