Zendure A5 power bank review (second-generation)

Zendure's A5 is big brother to the best power bank on the market, the Zendure A2. It's bigger and it's better, but a little more expensive and a tad less portable. An excellent choice for longer trips away from home comforts such as mains electricity, we review the 16,750mAh Zendure A5 power bank.
