I’m a fanatic about keeping my cellphone charged up, but some days I still come up short. No wonder I’m impressed with this slick little device-- an emergency battery small enough to fit into a wallet.
The ChargeCard comes in two flavors. One version has a built-in micro-USB cable that fits most Android smartphones, while the other has the correct cable for plugging into an Apple iPhone. For some reason, the iPhone version isn’t listed on the company’s website, but they sent me one of each to try out.
Operation couldn’t be simpler. You power up the ChargeCard with a separate USB cable that taps into your personal computer. Once fully charged, the device is supposed to give up to two hours of talk time. You just push the clear button on the edge of the device, plug it into the phone, and start dialing.
There are plenty of backup phone batteries out there, but its unusually compact design makes the ChargeCard a particularly attractive option.
