Solar Charger Power Bank 25000mAh with Flashlight Sendowtek PD 18W Charging 7.5W/10W Wireless Portable Phone Charger 4 Output&2 Input Huge Capacity Backup Battery IP54 Rainproof for Camping Hiking

I was looking for a good heavy-duty power bank, and I am quite impressed with its performance.Pros:1. This is a solid power bank with a huge capacity of 25K mAh. To put that into perspective, an average phone these days has a battery capacity of 3 – 3.5 mAh, which means with one full charge, this battery bank should easily charge well over six average phones to their max limits.2. Has both USB type A and type C outputs. The charging speed for the type C port is pretty fast – as fast as my actual charger.3. Has a solar panel, which automatically detects sunlight, and starts charging itself. (Of course, it does come with a cord to charge it electrically.)4. Has a bright LED light. This, together with the solar panel, makes it a great versatile tool to have while camping and/or during emergency.5. Looks pretty rugged and it should be rainproof. However, I’d minimize direct contact with water as much as possible (put it inside a Ziploc bag while travelling).Cons:1. It is heavy and bulky (which is expected given its 25K mAh capacity, solar panel and features such as LED flashlight), and not the most portable power bank. If you want something light and thin, this is not the power bank for you.2. The USB ports are very close, and if you have thick connectors, you might find it difficult to charge more than one phone simultaneously. That being said, it charges pretty fast (at least with the type C port), so charging multiple phones simultaneously might not be really necessary.

What I was looking for: a rugged high-capacity power bank with Qi fast-charging capability.Pros:- Great capacity, most others on the market were between 10-20,000 mAh.- Inputs are both USB A and C, with quick re-charging. Silicone cover protects against water penetration.- Qi charging is not only convenient but also fast (~1%/min)Pluses:- Battery indicators are fairly accurate. I tested multiple charges of my iPhone 8 and each bar/light faded after about 1-2 charges- Solar panel is nice but very slow; it comes in handy on long backpacking or hiking trips as an emergency source. However, on the positive side, it automatically recognized available solar power even in dim light and began charging.- Hanging hook with carabiner (not very robust but convenient for tent camping). Padding around the device is good enough to withstand drops from reasonable heights. The recessed chamfering of the solar panel is also a good design to prevent unnecessary damage to the panels. Some of the reviews on here noted “jostling” of parts inside the casing, but that’s not the case.Drawbacks (Cons):- The flashlight is pretty dinky, not much better than a dollar-store LED headlamp, but useful to have as an all-in-one tool.- Can get really hot when charging via solar panels in direct sun- The Qi charging is on the opposite side of the solar panels, so it can’t do both at the same time (not a big deal)

-the rubber pads in the corners can come off if you angle it right against another object. Maybe if they used glue to keep it in then that be great! it's not easy to get off tho, for me it came off and it took me around 8 minutes to put it back in.-the solar charging is a treat on the go, but when I charge my Galaxy S9 plus on wireless charging features it warms up the bank and my phone, alarming me a bit. I would recommend taking your phone out when it's 98 - 99% charged. it wasn't that hot but you could feel it for sure vs a phone running a demanding game while in your pocket.- I don't really see the purpose of the flashlight on my bank when my phone has it already, but there are phones that need the app downloaded to make that work. I guess I'll take that as a plus.- not going to complain about the one power button being used to turn flash light on (holding Power button for 2 seconds), turning on the bank (one click), turn off bank (two fast clicks).- given the features I wanted most out weigh my preference of the bank's size being twice that of my wallet, I think I will manage to love it yet.- the bank comes with a little clip with inwards opening clip that works with the small metal bar found in the banks design.

ordered the sendowtek 18w fast charging qi wireless charging solar powered power bank back in beginning of jan and it is TRASH - i wouldn't give it a 1 star review - but that's not allowed. i received my 1st purchase and it had a damaged usb port that was unsalvageable and the battery pack was loose inside the case and rattling - ordered a replacement and it was much better and solidly built but after discharge and full charging conventionally, i realized it produced less than half of it's advertised specs and then i tried to charge it with solar - and it will not charge after over a month in the sunny window it doesn't even have 1/4 charge at all. . the charge indicators show charging but status doesn't update or display progress - maybe because it wasn't charging at all - it was in direct sunlight. - this is a very poorly constructed product at best - do your self a favor and get a "goal zero" or some other NAME BRAND that will have a warranty and actually perform as it's designed and advertised to. if it weren't for amazon's friendly service, i'd be stuck with something that doesn't work.

1. The advertisement says rainproof.But, the 2nd caution bullet says to not leave in the rain.2. It is mostly cheap plastic, not much rubber.3. The charging instructions are confusing, it says two are input and two are output, but which are 2 way? Which output is more powerful, they should be labeled.?4. No instruction on how to turn the unit off (LEDs stay lit after pressing power button a second time).5. Since this is supposedly high volume rechargeable battery, a high volume charging block should have been included, recommending to use a laptop to charge is lame.6. They include a business card to get $20 Amazon gift card if you give a product review. But you send a url/screenshot of the review to an unknown email address... sounds like Chinese government phishing tactics.
