Charmast Power Bank Quick Charge 10400mAh USB C Power Bank Ultra Slim Portable Charger LED Display Power Pack Compatible with Smartphone iPhone Huawei and MoreCarbonfree Certified

Excellent back up power for my phone I haven't use it for very long to give it a fair review but I can say it's worth it when you have revy low battery on your phone while out and about its half the size of my phone and it's very light small and compact it has a on and off switch with display and build quality is really good for a plastic device the cable that come with is you basic USB types a to USB type c and it charges all small mobile devices such as phones and head phones and ear phones not included laptops they have there own chargers functionality really good and I'm pleased with this purchase

Really impressed with this. It takes a while to reach full charge but once it does it goes on to charge items quite quickly. Looks expensive too.

Wasn’t sure quite what people meant by slow charging, but it took 36 hours to charge 30%. Thankfully it arrived 70% charged already and I will only be using it for topping up my phone while on a trip, but definitely the slowest charging power bank I have ever seen

A sturdy product that can charge my IPhone 11 Pro Max 2x over from flat battery.Has a digital display to keep track of drain. Has 2 c usb a flat and 1 x USB c connector.

This has been a godsend. I now have to get a bus to work and the first bus app drains my phone's battery sooo much despite turning it off once I am at work or home. Cannot turn it off whilst on the bus as wifi is sketchy and we now have bus police who will kick you off if you cannot show them your e - ticket.I love the display with how much power is left and I have not had to recharge this unit since purchasing it despite using it regularly. It charges my phone extremely quickly.Compared to my husband's power bank this one is smaller and lighter but has the same power output.Also love the little dust cover as it protects the unit and is a safe place to store the lead with the unit.Overall I am extremely happy with my purchase.

Its quite light, easy to use and its handy having the two usb points. It does take a whole to charge up, but I do that of a night time, cheaper night time electricity too! I also like the little jacket to keep it safe from knocks. Overall its very good value for the money.

It’s a good portable charger and looks nice but it takes such a long time to charge. I’ve been charging it for 2 hours and it’s only at 50%. Not great for last min situations

Most power banks need a minimum draw of around 50mA to stay 'on'. If you are running very low current projects this is a frustration. The Charmast device has a soft work around. Plug into the USB-C socket, press the power button until the capacity display comes on and then press and hold the power button for a few seconds. The last digit of the capacity display will now cycle round its segments and the unit will remain on with sub 50mA loads.
