Solar Power Bank 30000mAh, Solar Charger PD18W QC3.0+6 Outputs+Type-C+Wireless Charging, Portable Fast Charger Power Bank with Bright LED Flashlight and Waterproof IPX6 for Outdoor Activities

When I found this in July 2021, there were two options on the listing; i9 and i11. Since the listing was not clear on any differences (and I posted the question, but no one answered), I simply ordered both. And guess what I got?: Two of the exact same model. The only difference was the price. ($5 then, $7 as of this writing.) So the more expensive one went back.Otherwise, yes it is a bit on the large and heavy side (check the specs in the listing!), but it lasts a long time and wireless charging works great. Although, I did have to fool with it a bit to find my phone's optimal placement. But now that I have, it connects right away and registers as "Fast Wireless Charging".

This battery is quite the scam, I regret this purchase since the first day I received it. It offers wireless charging but if you try to use it, the wireless charging turns off after 10-20 minutes and you have to push the button to turn it on again. This could probably work if you are sitting right next to it watching it constantly to turn it back on every time it turns off. This was the main reason I purchased this and with it turning itself off constantly it makes this feature useless. I tried using 3 different devices with wireless charging and this issue occurs every time so this is not a problem with the device being charged.After almost 90 days of use the battery will no longer turn on. I tried charging with USB-C and Micro USB, none of the lights turn on anymore. Tried solar charging but the solar charging light also does not turn on in direct bright sunlight. Even when the Solar feature worked, it was so incredibly slow to charge I did not even get a single extra pip from sitting in the sun all day.I immediately contacted seller when this failed, hopefully before it falls out of warranty. Will update this review if the seller responds. If there is no update then the seller never replied to me.Update 09/21/2021:Two days after the battery stopped working, I heard creaking and popping coming from the battery. I investigate to see this battery is now bulging on both sides and stressing the case, making soft cracking noises like the case is about to break open. See attached pictures showing this product bulging. This is an extremely dangerous situation and I don't know what to do. This is a large battery with a lot of energy and I'm scared it is going to explode any moment now. I have placed it outside so at least when it does explode it won't burn my house down. STAY AWAY FROM THIS PRODUCT!!! Unless you too want to take a gamble with your life and property.

Was excited to revive this and put it in the sun right away to charge it. Had it out for about 8 hours of full sun and the charge indicator never went past 50%. I tested some the features (wireless charge and lights) and they seemed to work fine. Tried one more day to charge it to 100% and gave it another 8 hours in full sunlight and same thing. 50%. I am very disappointed so this is going back. Also included are a mini carabiner but not sure why as this will rip a pant belt loop right off it's so heavy and also a very short (like 3 inch) USB cord that is almost useless.

What can't I say about this? I use it so often I forgot to write a product review because I assumed everyone knew it was that great and it just works! After spending a month or so of power going out at home, I was thinking of just getting a power bank for my phone. But then i realized something, what if my phone dies meanwhile i'm waiting for the power bank to kick in and give me light as im in the crawl space in the dark... guess what happened? Just that! Well after getting this I was impressed and surprised of how F-ing well this works! I used it to charge my phone and my Nintendo Switch and PSVita, so I had battery and gamed in the dark as I waited for my stuff to charge! BTW leave this out in a well lit area because it will charge do to the sun! I forgot to recharge it on the cord and left by the window on a hook in case I need it on my walking trips, and it was fully charged! I forgot it was also solar powered! I can go on forever, but get yourself one!

It is very heavy and difficult to lug around. The wireless charging part doesn't work. The directions were obviously written by someone who was translating from a Chinese/English dictionary . The two languages have very different grammar, syntax and idiosyncrasies and do not translate word for word. Even though the words were English they were not put together so that they were understandable to someone who actually speaks English.

I have a small garage that is not connected to power. I have been using this solar charged battery pack to power several led lights and a security camera on that box. So far, it has been working great and I have yet to try to use the lights and found the pack discharged.For it's intended purpose, it would probably be a little big for most people to carry daily. But for someone who is expecting to spend some time off grid this is good insurance that you will be able to charge your phone, radio, and/or camera when you need to.

We bought two of these for a camping trip. When we got them they were only at a 50% percent charge. We left them out in direct sunlight for the entire day and they still stayed at 50%. Obviously we had to use them. We drained them both and left out all from a Friday to a Sunday in the sun and they wont even charge to 25%. The 25% blue light is still just flashing after 3 days. Complete waste of money as we are outside of our return window. We got home and pugged them in to a wall out for about 4 hours and guess what, the 25% blue light is still flashing. 100% complete and utter garbage.

So it came well packed, had 3/4 charge out of the box, but the light and the wireless charger do not work. Also went to fast charging for the first 30 seconds with wire charger, then dropped back to regular. Can't get a hold of the seller either.
