We found the perfect power bank for outdoorsy folks. No, really, we have! Because this power bank doesn’t just have a massive capacity, but it also charges by simply being in the sun. The best part is that it’s only $25.90 at Amazon, a good 28% under its MSRP.

Let’s start by saying this power bank has a 42,800mAh capacity. That’s absolutely massive! It’s enough to recharge your phone fully about eight times. This power bank has two USB-A and one USB-C port, so you can charge multiple devices at once.

Since durability will obviously be a concern when you’re out and about in nature, you shouldn’t worry about this power bank. It’s not only IP67 waterproof but also drop-proof and dust-proof. However, we’d probably be careful with that solar panel.

You can hook the power bank to your backpack so it’s always exposed to the sun and, thus, always recharging. Otherwise, at that capacity, you’d need quite a bit of time to get back to 100% if it drops to zero.

As a bonus, the power bank also comes with a built-in 200-lumen flashlight that will come in handy at night.

So there you have it — the Mregb solar power bank with 42800mAh is only $25.90 right now, an absolute Cyber Monday bargain that you need to get your hands on.
