This thing is a life saver. Charges pretty quickly. Love that it has a type C & apple charger built in.

Nice thst cords are attached. Takes a bit to charge though.

Works great and last long but bulky. I carry it in my car not convenient to put in pocket or heavy to put in purse. I use it for emergencies. LED flashlight is very good also . It helps that cables are connected to battery.

Fast charge....able to charge more than one device at a time due to different cord attach...perfect in size and weight and it is very lasting.

New, out of the box, I let it charge overnight with the same charger I use for my Samsung phone. This morning when I checked it, the battery had swelled up to the point where the entire case had completely opened up!!! And, it was hot, so I'm scared thinking this thing could eventually catch fire! I suspect I received a bad one because during the first hour or so of charging the charging indicator never showed a readable percentage, it was too dim to read.I really needed this thing and was tempted to order another one but afraid of doing so because Amazon credited me (since I can't ship it back with a very swollen battery. I really needed the way this one was designed (large capacity; built in cords!) I tried to reach out to the company to see if they could send another but there appears to be no way to contact them.

I love this block. Can definitely charge 3 phones completely. A little on the heavy side but with taking with you.

I've got a few PD (Power Delivery) tools to measure the input/output to chargers and I absolutely cannot get 15V or 30W out of this thing. Using several PD chargers, the best I get is 12V and 20W both input and output. I can get 5, 9, and 12V. When I program 15V I get an error.So far, it's not close to 40,000 maH. That would be 148 wH (3.7v * 40,000maH). I do see about 100wH when charging and maybe 88 wH charging my devices (Pixel phone and tablet).Edit: I decided to send it back and get a replacement. Only took 2 days so that was nice. However, as I'm charging it from 84%, it's still clamped at 12V and 19.5 Watts. I tried my programmable PD cable and it won't go to 15V. Looks exactly the same. Once I get to 100% I'll trying charging my phone and tablet again. I honestly don't expect to get more than 20,000maH.Edit2: I decided to send it back. Amazon needs to quit selling these 'high capacity' banks that don't even close to meet specifications.
