FEELLE 50,000mAh Solar Power Bank Unfolds Four Panels for Outdoor Device Charging

Four solar panels fold outward from the FEELLE 50000mAh Solar Power Bank, priced at $62.99 today (was $70), spreading across a wider surface than the single flat sheets found on most packs in the same size range. Each panel sits on a hinge that locks into place once opened, so the whole array can face the sun while the main body stays flat on the ground or hangs from a pack.

The panels are covered in monocrystalline solar cells, with lithium polymer batteries inside that the manufacturer claims have a capacity of 50,000 mAh. After accounting for all of the conversion losses and heat generated by the device, the real-world output will be approximately four or five full phone charges. That should be plenty to keep a small group going for the weekend, or to get through a few days of power outages. On top of the unit is a magnetic pad that can deliver up to 15W of wireless power to any phone that supports the standard, such as iPhones. It’s a great feature for anyone interested in wireless power. If you prefer the traditional method, there is a cable slot available.

Four cables pop out of the side: one USB-C, one Lightning, one micro-USB, and one USB-A. You also get three other slots for extra cords, allowing you to power six devices at once, which is useful if no one in your company remembers to bring a charger. The USB-C connector, in particular, supports fancy fast-charging protocols like PD and QC 3.0, and can charge a phone from zero to 60 percent in half an hour when the battery is full.

In case the sun decides to disappear on you, there is a hand crank on the side that you can use to generate a small bit of electricity, as steady rotations at a reasonable pace will keep a light going or provide enough power to make an emergency call. The light itself is on the front, with a little button that allows you to cycle between steady, SOS, and strobe modes with a long press.

One of the nice touches is a small compass on one end, which allows you to find your bearings even after you’ve removed the bank from your pack. The ports are sealed with silicone covers to keep dust and light rain out, and the corners have these small rubber bumpers to keep it from becoming too scuffed up. When folded, it measures approximately 7.24 by 3.54 by 1.97 inches and weighs about half a kilogram, making it tiny enough to fit in a vehicle trunk or daypack while remaining strong enough to resist some harsh handling.

People have noted that the panels charge up on a bright day, but don’t expect to fill them up in a few hours. In fact, it’s usually a good idea to just use the wall charger that comes with the USB-C cable because it’s the quickest method to have it fully charged before heading out. Once you’re out there, the combination of solar input, hand crank, magnetic pad, and cable options ensures you don’t have to bring a different charger for each phone or tablet in the group. The three-year warranty is also a welcome addition.
