Gear review: ToughTested Solar 15 Powered Battery Pack
At 15,000mAh, it’s intended to power your smartphone 10 full charges, as well as tablets (2½ charges), portable games (17½ charges), GPS units (7½ charges) and “action cameras” (10 charges).
The Solar 15 also is equipped with a 200mAh solar panel, although there was nothing in the product material that says how long solar charging takes.
The dual USB ports allow charging your iPhone and GoPro at the same time, and a digital chip helps identify the kind of gadget and deliver the appropriate charge.
Another plus is the rugged exterior, although it’s unclear how much abuse it can take.
There’s a clip holder that allows attaching it to a pack or belt (although the loop isn’t quite large enough to fit well on a full-size climbing carabiner).
