While I’ve had limited use so far, I’m very happy with this product. It charged my phone quickly and well, and had plenty of capacity left over.

Took this on a week long hiking/camping trip. Was able to charge my phone and headlamp when needed. The cold weather didn’t seem to affect the charge. Only downside it’s alittle heavy

This charger is quite hefty (it's about the size of my iPhone 11, but weighs more), but it's so nice for concerts, vacations, and just day-to-day life. Both my friend and I can charge from this charger at once since it has two outputs, and even after charging my phone ~60% and my friend's phone for hours, it still had about 50% of its capacity by the end of the night. It doesn't have a bag/carrying case like some other Anker batteries do, but I think it's worth it regardless and I'm happy with my purchase.

We purchased this to extend the useage of our smart phones and tablets while traveling overseas. Having a 10 hour flight this device worked great to extend the usage of those devices for games,audio books and movies. We also had excursions up to 12 hours a day and this extended the use of an aging cell phone for plenty of picture taking and phone use. Definitely worth every penny and fully met our expectations.
