Where’s your iPhone 5 charger just when you needed one? The ChargeCard fits in your pocket so you’ll always have a back-up on hand. The idea started as a project over at KickStarter and was completely funded by August last year.
There’s one for Android phones as well (using microUSB) and even the older iPhone 4. Each ChargeCard costs $25. International shipment costs $35 so I decided to just use GCash AMEX card and have it shipped to the California drop-off address (got charged an additional 9% state tax).
