It features a 2300mAh built-in battery (equals an additional 10 hours talk time) and lip to keep your phone safe. Wirecutter thinks it’s one of the best available iPhone 5 battery cases on the planet, in fact the second best behind only the Lenmar Meridian — mostly due to it being a slightly slower charge and usually more expensive.
“Quite frankly, it comes down to price: We consistently find the Meridian for $5-$10 cheaper than the uNu. But if that changes, and you don’t mind the slightly slower charging speed of the uNu, you’ll do just fine picking the DX up instead,” said Wirecutter.
If you don’t mind waiting for shipping, you can still find the red, black and gold option for $50 on Groupon as well.
