First it does not have batteries in it. It unfolds and u place it in the direct sunlight if u have it. Plug the appropriate addaptor in (not included) and charge your device. I let my smart phone go to 5% and plugged it in with full sun and it charged up. Slower but it did charge......A laptop or tablit??? Then a power bank such as an Anker charger I don't know. Well try. In an emergency its certainly better than nothing

This solar panel works great when camping or hiking as you can charge power banks or usb compatible devices like iphones or android smartphones without a power bank. I prefer to use this in combination with a small power bank though to keep my devices topped up when camping for multi-day trips.
While it's built well and provides a good bit of trickle power when in direct sunlight, it is a bit heavy. Size wise it's comparable to an ultrabook or large tablet so ultralight backpackers will want to get a smaller version. I'd recommend getting a longer usb cable so you can keep your phone or tablet in your backpack or in the shade when charging.
Overall I have no complaints really, works great so far.

Perfect for charging cellphone or rechargeable flashlight! Easy to pack and easy to use. Works even with indirect light.

I wouldn’t call myself a hiker but I occasionally like to hike and camp. I usually take a bunch of battery packs without a way of recharging them. This was super handy; it's powerful and built tough. It did get into the water a bit, but there was no issue as its waterproof. I also like to prepare for emergencies, like the last ice freeze that hit the Texas area in 2021, when we lost power and couldn’t recharge our phones or listen to the radio. When not in use, this will be kept in my prepping bin. Really no complaints, worth the money.

Finally decided to add a solar charging option to my EDC kit by picking up this foldable solar panel and I'm glad I did. It's simple with no exposed wires, reasonably sized when in use or folded up, performed well out of the box and the material feels durable. My phone charged about 20% in 15 minutes which is more than enough for me. Now I just wish I had two.

I recently bought one for myself and my brother in law for emergencies and for hiking and have been very very happy with the product I’ve tested it several times and it’s worked perfect! I would recommend to add to your emergency kit!

This is a very powerful solar charger and works like a champ. You can feel that it is well built and sturdy. For sure it will last long time. It can quickly charge my Iphone and tablet at same time. One time it even charged my phone in a couple of hours in cloudy weather. Love it! Highly recommended.
One thing, I'd like to point out is that it is a little bit heavy for serious backpack campers.

I fly a few different UMX micro planes and they take the tiny 1s 3.7mah lipo batteries. By the time I'm done using the 2nd battery it charges 1 full battery. Takes about 40 minutes, but that isn't a problem for me while I chat it up with other RC pilots. I usually head out to the field with 6 batteries anyways. I di keep the charging and battery in the shade, while the solar panel is in full sun. Some of the guys charge 2s batteries with these, so it does work. I like that I can hang this off a backpack, and it doesn't seem too fragile to me. I haven't went lately, but I do go camping and it is nice to take a solar charger for emergencies which trust me can happen easily, if your not careful (leaving your phone on while in the deep woods, and battery drains). Overall happy with it, and works fine for my situation.
