Bests & Worsts Reviews from Amazon

This is now my second time leaving this review. I am unsure why. Just yesterday it was up with 12 people voting it useful. I will once more relay my experience, because I will not be silenced. I purchased this product expecting to receive at least a 40,000mAh power bank. That is NOT what I received. I tested this product in three ways, with 3 different charge cycles for redundancy. The current was measured with a power meter and charge controller. When I first received the product, I charged it fully. I was excited. This was meant to be a gift for my son, but I would soon learn that it was not worthy of gifting. One full charge on my iPhone XS Max and 1.5 Apple Watch charges completely killed the power bank. My other 40,000mAh power banks can charge that phone around 8 times from dead easily. So, I investigated. I first drained this power bank, and tested (with my power meter/charge controller) how much charge it took from the wall, which is how capacity is rated. It charged in 7 hours, and took exactly 13,800Ma of charge. I then took my 40,000mAh power bank, and tested how much it would be drained by charging this one. It had exactly 65.55% charge left after charging this power bank from dead. 40,000 x.655= 26,200mAh left on my power bank. 40,000-26,200=13,800mAh. My charge controller reflected the same numbers during this test. Triple confirmation. This is a 13,800mAh power bank, which is a common smaller Chinese capacity. Actually, if you search Amazon for “13,800mAh power bank” clones of this one come up, same wires built in, same inputs and outputs, all exactly the same. The wireless charging charges at 3W, and none of the outputs charge above 5w. The solar panels charge at 4W (400mA) in direct sunlight, which is less than 1/3 the advertised charging rate. It would take 55 hours of direct sunlight to fully charge this power bank. I expect that resistance from the cheaply made motherboard and wiring causes this to prematurely die as well, because even a 13,800mAh power bank should be able to charge an iPhone XS Max 3.5 or so times, as the iPhone XS Max has a 3,174mAh battery. This does not happen, though. It charges it from dead one time, and lasts one full Apple Watch series 6 charge before it is so drained that the flashlight won’t turn on. Which means that it is, in practice, a 4,000mAh output capacity power bank. After posting my initial review, I have been Emailed and harassed with bribery offers to remove or change my negative review. That explains why so many good reviews are on this horrid product. I do not sell out so easily, though. I will repost this review as many times as is necessary to protect future buyers from being scammed as I was. My advice is to absolutely NOT buy this product. Pay attention to the negative reviews. You will be staunchly disappointed if you are aware of what a 40,000mAh power bank is capable of. You will then be harassed and likely bribed to remove or change your honest review, which is extremely sketchy. That is the totality of my review. Dear lord, please do not purchase this. You will not have a good experience at all.
