Portable Charger Solar Charger 26800mAh Solar Power Bank Detachable Solar Panel For Outdoor, 2 Inputs 2 USB Outputs, Water-Resistant Charger Pack with LED Flashlight Compatible Most Phones, Tablets

The product itself looks like others. But the charging capability whether on spec or real life, is good. So far I'm satisfied with it and would recommend it to anyone that needs the USB charging device when hiking or traveling.

4 solar cells with 5.25" x 2.5" (6.4mm x 13.4cm) effective area each (52 sq in, 340 sq. cm total) gives this charger a great rate of solar charge capabilityCharging this massive battery will take time. That being said,the blue light indicators aren't a great gauge like most vehicle gas gauges. I have used it used it five times now.The first use I inadvertently I used the Type-C (input) to try and charge my Google Pixel 2 with the Type-C cable. I did not pre-charge the battery. Don't laugh I read the instructions after. What I found: My phones 2700 mAh battery was @ 83% and it drained to 0% (2240 mAh if discharge is perfectly linear + the suns power 05/23/20 @ latitude42.7284° N, 73.6918° W) in one hour. It may have taken less time but I checked it at an hour assuming I was charging. This produced a charge "indicator" status of 2/5 blue lights on the case. So theoretical max number of lights with just the pixel charge alone should be 1, donating only 2240 mAh from the phone ( 20% of 26800 = 5360). The sun must have been effective. Producing 2 lights 10720 mAh max and 5360 minimum minus the 2240 from pixel that equates to between 8480 and 3120 mAh/hour coming from the sun. Min charge time extrapolated is 3.2 hours (unlikely) and max charge time from empty to 26800 is around 8.6 hours(assuming direct overhead unimpeded sun). I will experiment more after 3 charges. I will also experiment with the "time to no charge" based solely on a google pixel 2 consumption.I then realized my mistake when my pixel 2 wouldn't even turn on. So next I charged my Galaxy S4 2600 mAh battery from 34% to 70% in 1 hour (the charger now indicated 1/5 blue lights) This also took place in bright sunlight. This used 936 mAh of charge. The sun provided an estimated 3120 mAH/hr thus meaning the phone had at minimum 4426 mAh charge left.The next day on a perfectly sunny afternoon I tested the solar charging capacity with no device attached. I tested between 2 and 4 pm at the same latitude listed above on 05/25. In 2 hours the charge indicator went from 1 to 3 blue lights. Assuming 3120 mAh/hour the charge should be 10,666 mAh charge remaining - this could make 3 blue lights indicate (rounding up to assume just above 40% triggers the 3rd blue light) It seems about as accurate as a gas gauge)The charge ability of 2 amps @ 5 volts is amazing. The battery is great.The 2.4mm phillips head screws on the detachable panel are nice, but I doubt I will ever remove them. I expect dirt, debris and repeated friction for removing and installing will shorten the life of this device.I already had a 5 year old spray water all over it with a hose (on jet) and it was fine.Good product. Take care with the folding cells and you will have a good product last a while I suspect.I will update with more info.

It took forever to charge. More than a week.

My best frend bought me this power bank. when it is full charge it has a lot of power. can charge my a9 samaung 7 times.But when the power bank is empty the solar panel( in full sun) do not have the power to charge the phone!!!!What is the point to have solar panel if it is not working when you need it!!!If i whated only power bank ther is beter options.Summary: as a power bank only it is good and have lot of power, as a emergency divase it is usless.the big pro is the panel are detachable.

I received this power bank as a gift. It didn’t charge properly, so I contacted customer support. They asked me to try a different charging cord; I did, but it didn’t work. When I contacted them again, they immediately shipped another unit to me. This one worked perfectly. It really holds a powerful charge, and quickly recharges phones and pads. The solar panels are a definite plus, giving you a charging option when you don’t have access to power. Very handy product, I’m glad I have it.

I wanted a power bank with a LOT of juice and quick charging power for camping, school, work, etc. without worrying about getting one charge out of it. I need my phone and iPad charged daily for work, and this thing delivers! I love this thing and look forward to many years of use!

Great idea but couldn’t get the battery to charge with solar power. Tried a sunny window for a week, tried outside in the direct sunlight for a week. Lights indicated it was charging sometimes but remained on one blue light (low battery). Would only charge while plugged in so I returned it. Will try another.

Be-charming solar power bank with plug in charge abilityModel : TN4ANOTHER ONE BITES THE DUST AGAIN"!!! Bought this about a month ago. Lasted about a month. Everytime I buy a solar /wall charger battery pack for my phone I have to buy another one shortly after. They are not made to last. They are made to keep you buying them. People need to wait a month or two before giving a review instead of giving good reviews right after getting the device. These solar chargers are crap!!! Not buying any more.
