The Best Specifications & Great Build Quality – Replacement Is Working Great
UPDATE: Now a 5 star rating – due to quick and pro-active customer service from Moskiz, and as expected performance from a new power bank. Congratulations to Moskiz customer service to see my original review and stated problems, proactively reach out to me, and offer to send me a new one.I have had the new power bank for a week and have put it thru a host of different charge and discharge regimens – exercising all (3) of the USB A ports, the USB C port, as well as the wireless inductive charging on a couple of phones, and watch, and the different modes of the built-in flashlight. So far, all have worked flawlessly and my confidence in what I have already noted as the best specifications and great build quality in my 1st review below – is now restored. What do I mean by best specifications? Well, many of the cheaper alternatives out there only have wireless charging of 5 Watts (1 amp at 5 volts), this charger offers up to 2 amps at 5 volts (or 10 Watts) – depending upon if your phone can handle it (my iPhone 11 can handle 7.5 Watts, and the appropriate LED on this wireless charger shows this higher charge rate (vs the slower 5 Watt charging rate that is available on this power supply – depending upon your equipment).It’s nice to have these higher wireless charge rates vs. the 5 Watts that most other devices offer. Many of the other manufacturers also only offer 5 volt 2 amp charging for USB ports – whereas this offers 5 volt 3 amp charging (again, if your equipment has the capacity to charge at these rates).The flashlight on this is crazy powerful, and would truly come in handy if you ended up on the trail later than you hoped, or in an emergency situation.The new power supply when fully charged shows 4 blue LED’s for the first 5 seconds, then the first 0-25% charge LED (adjacent to the green solar LED) has a red LED turn on – which is an indication that it is looking to pair for wireless charging. About 5 seconds before the power indication LED’s turn off, the first LED turns back to full blue. I mention this only because I’m certain the first one I received did not do this in the short time I had tested it before it died. This might explain why it was defective from the start, or that a hardware and/or software fix has been put in place.In terms of the solar panel, all brands seem to be upfront these days saying that they shouldn’t be counted on to charge the battery sufficiently. For me, the carbon fiber on one side, and the solar panel on the other are part of the cool looking packaging. If you want more out of it, your expectations from such a small solar panel are un-realistic. My solar panel LED activates, and the status LED’s show that charging is occurring – but as someone else stated this should be considered more of a maintenance trickle charge than a functional charge. Just as you wouldn’t leave your cell phone in the blazing sun, or a super hot car – this charger should be treated with the same respect.Hope this has been helpful. I will continue to update if I experience any issues over continued use and testing, but at this moment it feels like this is a solid product that I can expect to get significant use out of. Just be sure you don’t try to fly with these larger capacity chargers – as my understanding is that TSA will confiscate this. As with any Li Ion or Li Polymer cells, personally, I will only charge when I am present.I would also suggest you test any new device for defects within the warrantee period. As noted, Moskiz reached out to me to make things right.ORIGINAL REVIEW: I was looking for something that would both survive being bounced around in a college back-pack for my son, as well as survive out in the wilderness on back-packing trips. Although the size and weight were slight negatives – this had all the best specifications in terms of charging rates and flexibility, water ingress ratings, and included a powerful flashlight (including an external heat sink). Upon receipt, the ruggedness and build quality seemed to be very good, with case halves that are actually screwed together (instead of a cheap press fit design like others). I was able to charge fully using the provided cable without any issues, and the solar light even indicated that the solar charger was producing a charge when exposed to sunlight or interior lights.Fast forward to a week after Christmas when it was first used to wirelessly charge. There was good pairing with an iPhone 11, even thru an Otter Box case – and it fully charged the phone that was previously at 75%. Then an iPhone SE was paired wirelessly, and increased the charge by about 15%, until it seemed to disconnect. When the power button was pressed on the unit to try to pair again, nothing happened. Other than hearing the on/off micro switch clicking, there were no charge indicator lights, no solar charge function, and no flashlight function. When we got home and tried to charge the power bank itself, still no function – it was a true brick!Sadly, the reliability of this power bank when charging our phones lasted less than an hour and a half of being brand new and without ever bumping it around in the real world.The good news is that I have to assume the built-in safety of the power bank picked up on a problem and safely shut the power bank off before any damage occurred to property. However, as this was only charging a single device, the unit wasn’t getting hot on its own, and wasn’t in an abusive environment I have to attribute the failure to an infant mortality/reliability issue.

This is my 2nd. One
This thing is so durable and so great that I have ordered another one two years later, I have dropped it stepped on it cracked it and it’s really in bad shape but in everything that has happened to this thing it still works it charges it’s wireless charging and the flashlight I’ll still works, I had to get another one that is in better condition and I will take better care of it than I did my other one but it is durable and I do mean durable LOL this thing is awesome

Worth the price.
This is the second battery I bought. The first one I took a chance on and I was very impressed! Charged it up from the outlet first as suggested, took it to scout summer camp and charged my phone as needed. It lasted about 3 days (with multiple charging users) before I tried using the solar charge option. It did not do well with direct sunlight charging in hotter temperatures (+85*). In cooler temps I would place it in the window sill of my car for emergencies and it charged fully with in a day or two. I would highly recommend this battery because of the other options included as well.
