Summertime is only weeks away, which means your weekend calendar is filling up with warm weather activities like hiking, bike rides and beach days. While all that fun in the sun is much needed after a long, cold winter, a major drawback to outdoor adventures is that they usually leave your phone battery drained on account of there being no electrical outlets in nature.

That’s why you need the Polanfo 20000M Power Bank. This handy external battery for smartphone and tablets holds as much power as six iPhone 7s combined — that comes out to an additional 84 hours of talk time.

What makes this power bank better than most for outdoor activities is it’s compact size. Roughly the same height and width as your bank card, it slides right in your pocket without bulging. At roughly 20% the size and only 30% the weight of other external batteries, it’s the burden-free way to carry backup power on all your adventures.

The polyner battery is encased in sturdy aluminum alloy with an attractive anodized finish. Plus you’ll always know how much power is left thanks to the digital LED indicator.
