2200mAh

Since late last year, the best iPhone 6 battery cases have generally included two things that iPhone 6 users now take for granted: enough spare power for at least one complete recharge, plus adequate coverage for the iPhone’s top, bottom, and back, if not its sides. PowerSkin has gone in a somewhat different direction with Spare for iPhone 6 ($80), a battery sled that caters to iPhone users who want less of everything. With a small 2200mAh cell inside, it’s the lowest-capacity battery case I’ve seen for the iPhone 6, and also offers the least body coverage, but sells for about the same price as more capacious and protective rivals.

Lightweight and marginally easier to pack in some bags than some rival battery cases, Spare is here for users who want a partial iPhone 6 recharge and anti-drop protection, but no anti-scratch safety. It’s offered in silver, gold, or space gray, currently ranging from $70-$72 based on your color preference. PowerSkin claims that it will deliver a 100% iPhone 6 recharge, but our testing found otherwise…
