Customer Reviews

I'm really impressed with this solar charger. VERY impressed. I've taken it with me now on one trip, and it came in super handy. I forgot the block for charging my phone and needed to charge up using the battery pack. But after about 4 charges, I was left with a dead battery and no way to charge either the battery OR the battery pack....but luckily, this is a SOLAR charger, with four panels and not one....so sitting in the sun I was able to get enough to charge my phone once a day for four days. All told this powered my phone for the entire week! I'm really happy about this!!! The sun powers it quite well and with four panels, it charges a lot quicker than a single-panel charger. The four chargers are nicely held in place by a snap! Very nice and neat. Also, it holds 25000mAH, the most that any of my batteries hold. I'm confident in saying that this is the best battery charger I've ever owned as far as how fast it charges and how many times I can charge my phone, and how many mAH it has. I know it's not a "portable" charger as such, due to its capacity and weight...but I will be taking this charger with me on trips from now on to be sure!

I have to say I LOVE this charger. It is sleek and powerful which are both of the things I need. It is just over a pound so it is too heavy for pockets but I carry it around all day for my tablet and phone for use at work and school and when I am on the go. I love how long the charge lasts and how much juice I get out of this battery pack. I love being able to charge it with the 4 solar panels if I need and it works great. This is a great everyday back up battery if you are busy and can’t always stop to charge your phone or tablet. I would recommend this to all the people in my class.

In terms of charging, I left the battery out on a table for few days for it to get fully charged. I have no previous experience in solar-powered portable chargers; however, this unit had survived through some harsher conditions. In the days I had left it out to charge, it had rained - the waterproofed battery still works as intended.
The battery charging via a wall plug is a welcome alternative if I am impatient, as it is quicker than solar-powered.
When testing the output of the battery with a phone, I found that it can recharge the phone multiple times in succession without a recharge. What is also welcoming is the speed of how fast the phone is charged. I compared its charging time with a regular wall plug, and the results show that the phone uses the same time with either charge source to be fully charged. That's a win in my book.
The flashlight (bright/SOS/strobe mod) may not have an immediate use for me, but the light the battery produces is very strong. Always nice to have a backup flashlight.
My sole gripe with the batter is its Micro USB cable as the input. I would have loved it if it used a USB type C cable.

I was really pleasantly surprised when I received this product. It's very attractive and well build. It's hefty, which I really like, and the leather case is durable. When I got the charger, I read through the instructions and it says to charge via the mains the first time you use it, then every 6 months thereafter to maintain battery life. I immediately charged it with the mains, and when it was finished, I used it to charge my phone. Everything works as advertised, and I was pleased with the charge time.

Another small thing is that there are 5 holes on the side where you can see how much battery the thing has left, and whether it's charging, but the LEDs are pushed back into the case, so it can be hard to see which lights are actually lit up and which aren't. Not impossible or anything, but definitely not ideal.

The flashlight is bright and all of the features (like solar charging) work as intended, and I am actually still really happy with the product and am continuing to use it.

I was expecting this solar power battery pack to be a little bigger lol, but I like it for the portability. It has four solar panels, each panel is about adult palm size. 2 USB for output, and 1 micro USB for input charging. I would have hope for usb-c, but alot of these chargers are still using m-usb. Although it's not as fast as my Samsung's fast charger, it still charges fairly fast for my Samsung S10. I hike with friends in the mountain trails often, this is a great gadget to include in my hiking equipment list and it has ability to charge 2 device at the same time, plus it includes a flash light with SOS signals. I recommend this.
