    The USB power bank came packed in standard Banggood shipping bag. Inside this the USB power bank front and rear covers are individually wrapped. They are reasonably well protected from damage but if roughly handled during shipping may take some damage as they were not protected by bubble wrap. This did not occur in this case as they arrived in good condition. The USB power bank consists of front and back covers which clip together after installing 10x 18650 batteries. The batteries I have a cheap generic lithium 18650s which I have had for many years. I made sure that all batteries were charged to roughly the same voltage before installing them as, once installed they are all in parallel with each other. If any very in voltage too greatly installing them may cause them to overheat and or damage the contacts or themselves. Once the batteries are installed the front and back covers just clip together and the small display cover can be attached to protect the display / circuitry and complete the front cover. Very happy with it overall.

    Fast shipping, working great: No over-heating or any other problem. The only issue I have is that it is hard re-open.

    This is a really long 30000mAh DIY battery case that holds 10×18650 batteries. The case fits and locks around the batteries cleanly but there is a bit of wobble, so if you plan to use this in a high-turbulence setting I would recommend adding some vibration dampening before locking the case. The LED is nice and very bright but the 'energy' button used to check the charge of the case is a bit cheesy, and the entire display area looks a bit cheap, unlike the rest of the case, which looks just fine. The case has two charge ports (micro-USB and USB-C) and two USB-A discharge ports, sadly at just 1A and 2.1A — there is no QC support in this case.

    Received, quite quick to arrive. The solder on battery (-) terminal on the board was broken off, probably due to some impact during transportation. Tested with a wire bridge and it works fine it is a matter of soldering the terminal back on. Quite bulky and heavy when fully populated with the 10x 18650 cells. Have yet to test the functionality, trust it will work as advertised.

    Good build quality. Not sure if it can deliver higher currents. Time will tell. 1A it can deliver for sure.
