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

Great power bank.brought it for my son.its a great design small and lightweight,easily fits into my sons school bag.great for a back up incase his phone battery dies.great quality as the phone charges really quick.

Bought this to replace a broken power bank. The clear digital display is great..my previous one had only 4 flashing lights when in use. This is much better and you can see when it needs charging up. Small and neat to pop in my bag when I’m out and about and it charges my phone quite quickly, although not quite so good on my tablet.

Understanding my ratings:Unlike some reviewers I do not grant five stars simply because a product is as advertised. Three stars for meets expectations/adequate. Products lose stars for failing to meet expectations but gain stars for going above and beyond.Purchased in April 2023 for £12.99. For this price the product is good value.The power bank is solidly built.As other reviewers have noted it can take a while to charge the power bank, but that's only to be expected for a 10400 mAh battery with a maximum charge rate of 15W. I have two of these and they take around seven hours to charge from empty to full, when charging at 12W. Sure, that's longer than the superspeed charging some newer phones are capable of but such charging should only be done infrequently, when absolutely necessary, and comes at a price. For this product the charging speed is adequate, and means you can easily charge the power bank overnight. We must also bear in mind that slower charging is better for the health of the power bank's batteries. If you absolutely need a power bank which will charge faster you will need to look elsewhere and be prepared to pay considerably more for it.My primary phone has a 3300 mAh battery. This means I can get three full charges from the power bank, so with the phone fully charged and one power bank I'm looking at four days use without needing to find a way to charge either the phone or power bank. With two power banks that goes up to seven days, which is plenty for a whole week away.Perhaps the key feature of this power bank is the twin seven-segment LED display showing the current charge in the power bank. This is far superior to the four-part indicators on many other power banks and is what 'sold' the product to be in the first place. The LED display means you can easily judge how much charge remains, how many more charges you can get out of it, and a more accurate estimate of how long it will take to fully charge the power bank than you would get from one of the lesser power banks with just the 25%/50%/75%/100% indicators (like my previous power bank). The display works well and displays in 1% increments.The power bank was supplied with a soft draw-string pouch. This was unexpected and will help keep prevent the power bank from being scratched, although the pouch isn't of a hard-wearing material, so will have its limitations. The pouch is large enough to accommodate both a power bank and a small charging cable, keeping everything neat.The thing which led me to seek a replacement for my previous power bank was that the charging socket had become damaged. Because this power bank has two sockets to charge from, if one becomes unreliable you will still have the other available.

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.

Definitely recommend this to anyone looking for long lasting power, this is a life saver when we go on road trips don’t buy cheap buy this!

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.

Good portable charger lost charge quickly from the charge it came with but once we charged it up again it held charge well. Charged my phone from 0% - 100% once which isn’t too bad

It does what it says! Very good value for the money & a good design & functional size.
