10400mAh Power Bank USB C Battery Pack with LED Display Type C Powerbank Portable Charger Compatible with Smartphones Tablets and More (Blue)

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.

Works and does the job and I love that it tells you how much battery life it has.Slight downside is that it is quite heavy and charging time does take a while (or maybe I’m just used to my fast charger)

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.

Does what it says and brilliant for the price. I’ve charged it and it charged my iPhone quickly without using too much energy. The indicator shows how much power is left and will probably charge my phone many times before needing tool re- charge it. It comes with a nice holder so you can keep phone protected. With 2-3 outlets cold probably charge all our phones at same time and maybe run iPad.

Light weight, works well , good size , easy to use

Its good for traveling but takes lot of time for it to charge

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.
