POWERFUL and works great

BeeNovember 13, 2025✓ Verified purchase

I recently purchased this solar power bank, and I’m extremely impressed with its performance.it can charge my phone multiple times before the power bank itself needs recharging. The built-in LED flashlight is very bright and incredibly useful for camping, hiking, or power outages. I also love that it’s water-resistant and dust-proof, making it perfect for outdoor use. The included carabiner is a great bonus, allowing me to clip it onto my backpack while it charges in the sun. The solar panel is a reliable backup when there’s no outlet around. The design is sturdy and modern, all the USB ports work flawlessly, and the USB-C fast charging is a huge plus. Overall, it’s a well-made, dependable power bank with excellent value for the price. Highly recommended for travel, emergencies, or everyday use Read more

You Must Buy It

ShavelFebruary 3, 2026✓ Verified purchase

Best thing since slice bread. lol 😆 loving this device a bit heavier than I would like but no biggie. The power holds up for long hrs its very functional and really good value for money. Takes a bit too long to charge. I was out of power for months as Hurricane Melissa did a number on Jamaica but this... this kept my power on my phone and tablet going. I will buy another just because. it's a great product. Read more

Great power bank.

Anthony DelPercioFebruary 1, 2026✓ Verified purchase

A very nice power bank, has everything you need to keep all your devices charged up and the solar panel on it works better than expected. Also has an emergency flashlight built in with several modes. Seems to be made very well. Everyone should have one available to charge your devices when no other power source is available. I plan on getting a few more so everyone in my family has one. Definitely a must have nowadays…!!! Read more

Great product, one disappointing flaw

SywenJanuary 29, 2026✓ Verified purchase

This power bank is pretty great. A little heavy, but i kind of expected that. The charge lasted for over a week with frequent use, the flashlight isn't amazing but it's definitely serviceable and it doesn't drain the power quickly. The solar charge works - it is slower than the cable charge but that was also expected. Ultimately I'm really happy with the product in general, my only complaint is that the post that the caribiner attaches to isn't strong enough to leave it hanging from a bag or backpack when teying to allow it to charge. The second time I used it this way the plastic snapped and I was only able to use the solar charger when I had the chance to lay it flat for the rest of my trip. Read more

Isn’t holding a charge

S. VanburenJanuary 24, 2026✓ Verified purchase

UPDATE: after posting my initial review below, it took an additional 48 hours to fully charge this battery pack for the second time, without having used it . It simply sat on the shelf overnight and required a full recharge. I don’t know if this works or not. The troubleshooting guide here on Amazon says initial charge time should be 9 to 10 hours. Mine took 48 for all LED indicator lights to stop blinking. I unplugged it and made sure it was off, it sat overnight unused. This morning since the sun came out I wanted to see if charging via solar panel also showed that it was fully charged. Not only did it begin charging via a solar indicating that it was not fully charged, I then plugged it in to my adapter and it has now been charging for an additional four hours, that last LED indicator is still blinking. I’m not sure there’s any point in having a power bank for emergency backup if it can’t hold its own charge. Read more

Good power, bulky, nice light, slow solar

Mr. GreenMarch 5, 2026✓ Verified purchase

So far it works well to keep my iPad and ADSB powered throughout 6-7hr flights. Usually never uses more than 40% Seems like the solar is pretty NOVELTY but if you leave it in the sun for a week or 2 it could fully charge it Read more

Works Great

DemetriaMarch 5, 2026✓ Verified purchase

I keep it in my window to charge daily. It's great for traveling long distance. Flashlight. The best because you don't need electricity to charge it. Read more
