This power pack is definitely not about speed charging but it’s good for emergency when you have to keep your phone charged, expect a lengthy charging time for it to charge to about 50%. I tested it on multiple devices with battery capacity ranging from 3000 mA to 6500mA. They all charged at the same rate of speed.

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!!!

just got this solar charger and it is great. Now I’m ready for the next power outage. It came 75% charged and took about 30 mins to fully charge with a wall outlet.
It came ready to charge my phone wireless. I just put my phone on it, pressed the one and only button and it did the rest. Lol , I read the tiny book but didn’t have too. It was plug and play. The flashlight is not that bright but works OK in a pinch. And the little compass is pretty cool if I want to play eagle scout. lol. The price is right on this . Check it out.

I’ve had this item for 5 years now and it’s amazing. NOT glitchy, cheap or easily damaged. It’s a great portable charger! It has a BRIGHT led flash light, 3 different ports for charging different devices. Charges with sunlight. Comes with a durable steel clip and compass. I really highly recommend this item to anyone that wants a reliable, durable power station!
