Power banks have somehow become part of our pat-down—phone, keys, wallet, and battery. But what do you do when you go camping or hiking? You get a power bank that recharges by sitting in the sun, of course. This solar-charged magnetic power bank is only $24 right now after a 40 percent discount ahead of Amazon Prime Day.

For starters, this power bank has a 10,000mAh capacity, which should be enough to recharge your iPhone more than twice over—and more since there are three ports available: one USB-C, one USB-A, and a Lightning port. So, you can wirelessly top off your iPhone via the charging pad and give your iPad a boost at the same time.

This power bank also has a solar panel on the back so you don’t need to plug it in to recharge its battery. There’s an LED indicator so you can check how much charge it has, and it even comes with an attached compass so you don’t get lost. And what’s more, the corners are covered in rubber, which makes it shockproof in case you drop it. Another cool feature of this power bank is that it features a pair of LED lights, so you can also use it as a flashlight in a pinch.

Frankly, this power bank is the ideal solution to keep your phone charged while you’re spending a day outdoors, and for $24 it’s an absolute bargain! So go grab one for your summer adventures!
