Dear Customer,

We're sad to say we have discontinued new sales of CoBattery products.

The goal of CoBattery was to replace conventional battery charging with fast battery swapping. We're incredibly grateful to the thousands of customers who purchased our cases and supported us in that mission. Phones have changed since we first started making cases over 3 years ago, and we'll be taking some time to reevaluate native battery performance. We hope that one day we can rely on our devices without needing battery accessories. If we find that day has not yet come, we may release a new product.

If you'd like to check on an outstanding order, receive replacement parts or a refund, or have anything else to share please email us at

Thanks again for your support.

CoBattery with Battery

Never plug in your iPhone again.

CoBattery is a case with a swappable battery that keeps your phone charged, no matter what you get up to.

Two batteries included.

While you use your phone, your second battery is charging at home.

Swapping takes seconds and each battery has enough charge for a full day.

Heavier than a feather, barely, CoBattery weighs under 5 oz.
Raised edges protect your phone from dings, divots and drops.
Your extra battery has a friend. We call it the buddy system.
Custom designed connector for power without the bulge.
You'll love CoBattery. If you don't? Send it back before 30 days.
Sometimes life happens. We include a one year warranty.

The world's sexiest connector.

Our custom designed lightning connector snugly fits your phone.

Just push.

Lightning Connector

Protect your phone's internal battery.

Lithium-ion batteries degrade as you use them. After 300 charge cycles, your iPhone battery will be at 80% capacity.

CoBattery takes this wear and tear instead of your iPhone battery.
