There are a lot of reviews saying solar panel doesn’t work, can only charge phone a couple of times ect…
It’s all about reading the specks and math.
Solar charging:
This device is small. It’s length and width is smaller than my galaxy s22 and only slightly thicker. I can easily carry it in my pocket. Putting an led in line between the Solar panel and the battery to indicate current flow is a very basic circuit. If the led that indicates the Solar panel is charging is on, there is current flowing to the battery and it is charging. There are excellent explanations in the question section which do a great job of explaining the math and why it would take probably over a week to fully charge this device. One review I read said the device would not fully charge with Solar. I “capped off” my phone from about 50% battery to 85% which used about one “bar” or one of the indicator let’s. I then put it outside in the South Florida sun, in direct sunlight to see if I could fully charge it with the Solar panel. It took 3 days. It finally got back to a full charge. Am I disappointed, NO, that’s about what I would expect. If you wanted to fully charge your phone, then recharge using Solar, the Solar panel would have to produce the same watage over a few hours that you used to charge your phone. You can do this with one of the folding Solar panels Amazon sells. These panels are huge in comparison to the tiny panel on this unit. It’s all math and physics. Hurricane Andrew back in the day, we were without power for a little over a week. Thus device would have charged my phone once or twice, then it would probably take a week to recharge. Not what this device was designed for.
“I can only charge my phone a couple of times before recharging”
Thus battery is small and easy to carry. If you are comparing power banks using the same technology, same type of battery, more capacity equals larger battery. Again math and physics. If the battery bank is about the same size as your phone, you are only going to get around 2 or 3 full charges with it. A power bank is basically all battery, so if the device is about the size of your phone the battery size inside is probably 2 or 3 times larger than the one in your phone. Thus expect 2 or 3 charges. Again math and physics. In an emergency situation, I would use this as a Solar flashlight. I have a larger power bank that is about the size of a lunchbox with a large folding Solar panel to charge it. Under perfect conditions I can recharge that device in about a day to day and a half. I recommend this device as long as you understand it’s limitations. Remember it can fit in your pocket, It has wireless charging, and is inexpensive.
BTW, the compass is just a novelty. If you are putting yourself in a situation where you need a compass for navigation, carry a real compass.

Wireless Charging or QI charging does NOT work with a Samsung Z-Fold 3
Overall not bad, I had a problem with the included charging cable , would not work, but I have other type C cables laying around so I asked if they would send me a new cable? We will have to wait and see what they do or do not do???
*** Side note, the compass is absolutely junk nonsense, and will not work whatsoever. I did not buy the unit for the compass so i really do not care about that.***
I purchased this if I am stuck on planes flying around for too long, and I realize most planes these days have USB outlets in every seat but just in case I am in a plane or spot that has NOT been fitted or retrofitted with USB outlets then I have access to a method to charge my hardware and peace of mind I have a contingency plan with me at all times.
The QI or wireless charge method does not work with my Samsung Z-Fold 3 phone, why I do not know, my powered car clamp charges the phone wirelessly through the back and through the sup-case Pro without any issues but this does not work that way. This does not have any way to clamp or connect the backup power unit to the back of a phone either. So when you use it, you will have to lay the unit next to your phone and let it charge via the cable. I cannot answer if the wireless/QI charging works with other phones or not or if case thickness have anything to do with it or not. But using the cable to charge my fold 3 is sufficient. Compass in the trash cause its crap, and I am happy with the charging performance and I should be able to charge my fold 3 about 3 or 3 1/2 charges to 100% before I have to charge the backup unit again so I should be able to go about 5-6-7 days based on usage without needing a power outlet so camping or long offshore deep salt water fishing trips, vacations where power might be difficult to get to, you are covered and do not need to worry about that and the Solar charging even though they warn you its not a 100% fool proof and high performance method, its slow it still is a backup method to charge your machines in the worst case scenarios. For the cost, it is difficult to beat this or a product like it. Would be nice if there was a way to connect/clamp/snap it to the back of phones. Somehow piggy back it to a phone and if it would QI charge a phone with a Sup-Case or Otterbox thick rubber case but protecting a $2200.00 phone is more important than charging it wirelessly to me even though my auto car clamp charges it through the case with no issues. Perhaps a better more $ model would be able to do these things but this model does not in my circumstance.
It seems fairly well protected with a poly rubber on the back and corners of it in case you drop it the unit wont shatter into 20000 pieces on the floor. Solar panel is recessed a little bit to prevent damage when on flat surfaces. For the cost you really could not expect much more. The flash light seems fairly bright up to a few feet. Not good for any distances but 2-3 feet to find something in a dark room its adequate and its weight seems okay for what it is. My Fold 3 is relatively heavy for a phone so adding about the same weight as a fold 3 or 4 is what it is. If you mind weight, you might want to look for a smaller backup charger not this. Its the size of a typical cell phone and twice the thickness. I think its nice to have this as peace of mind/contingency plan for power in case of an emergency or issue and for the $22 ish dollar price tag its difficult to get anything better
Hopefully this review will help spell out what you get, expectations, how it will work and perform.
Good Luck to all!!!
