This wireless smartphone battery is the most compact of its kind. Designed and conceived by Shaun Teblum and Rob Gold, the pocket sized bKey is currently seeking finances through Kickstarter, a crowdfunding site.
The emergency iPhone charger is especially handy as it attaches to your key chain. The small white device does not require any charging cables because the connectors are located on either end of the smartphone battery. The built-in USB tip makes it extremely easy to use and makes charging on the go more portable than ever.
It is intended for a backup charge, however, rather than a full powering up. The bKey will give you enough juice for a 30 minute conversation and will hold its charge for up to 30 days.
