Review on 🔋 LHIABNN DIY Power Bank: Build Your Own External Battery Pack with 2 Output and 3 Input (Micro, Type C, Lightning) - 18650 Battery Not Included by Mark Toth

Update: Please don't waste your money on this junk piece of counterfeit device. I have a battery full of 18650s and it doesn't even charge my tablet to 100%. My tablet with a very low battery (i.e. doesn't take long to charge) went down to 60% and battery down to 10%. 90% of the battery charged my dead battery on the tablet to 60%. This is an outrageous and counterfeit device! There is too much loss in the circuit or something. It was also charged for FOREVER and discharged even faster. As. It just doesn't make sense. Save your batteries and make your own battery pack. Don't use that crap. Pretty cool device. It has two bad USB outputs, but all available inputs - micro-USB, iPhone and even USB-C for battery charging. I think you can even charge with multiple inputs. Not sure if it actually charges faster, but I used USB-C and Micro-USB to charge together. Micro USB and iPhone input is too close for my cables but it depends on your cables. Cons: Poor USB output. I don't know why but it charges my phone at half the power it can handle. It charges my device at 2.5W with the ChargerMaster app and at 5.6W with my Bluetti portable solar generator. So it's definitely charging slowly and I'm not sure how fast it charges the batteries. I worry that the batteries will take forever to charge.
