Brewcoat vs Oivo

Coffee Brewer's Ultimate Accessory

Brewcoat is a simple gadget you put on your brewing device, that keeps your brewing chamber closer to your brewing temperature, increasing consistency, and giving better extraction.

The smallest backup charger for iPhone

Oivo lets you recharge your drained battery on-the-go and always stay connected, without having to think about it. This might not happen often, but Oivo is the best solution when it does. No cables, no AC power, no fuss. Just add ordinary AA batteries and charge your phone.
