Charmast Power Bank, Ultra Slim 10400mAh Portable Charger Quick Charge | USB C Battery Pack 3 Outputs 2 Inputs, LED Display, Travel Essentials Powerbank compatible with iPhone 17/Samsung/Tablets

Bought as a gift, comes with a soft carry bag. Holds sufficient charge to keep 12 year old in phone battery when out and about.

Feels and looks like a quality, well made charger. Holds its charge well and when in use has different options for charging different devices and charging more than one at once. Recharging it is simple and efficient and protective sleeve is well made. Instructions useless, you have to work it out.

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.

This power bank charges devices quickly, which is really convenient when you need a fast boost. It’s lightweight and easy to carry around, making it perfect for on-the-go use. The only downside is that its battery doesn’t last very long, so you may need to recharge it frequently. Overall, handy for short-term use but not ideal for extended power needs.

Excellent power bank. Makes charging easy and quick too. Good value and quality.

I got this to charge my phone on the go and it hasn't disappointed. Its slim and small enough to slip in to a small handbag or even a pocket and looks stylish. It charges multiple devices at once and charges them quickly. Only down side is how long the power bank takes to charge up itself. however this wouldn't stop me buying it again as it lasts a long time and i have had multiple charges from this power bank

Works ok but not very fast at charging, for example same cable used in a other results in double the speed.

So happy with my purchase. Slim design and easy to have in your handbag. Build in cable is so helpful. Great product overall.

Ik gebruik de powerbank voor mijn S10 en het werkt prima. Quickcharge functie is ideaal voor onderweg en de powerbank laadt snel op met de usb-c port.

De charmast is zeer scherp geprijsde powerbank die 10400mAp in een zeer strakke en compacte behuizing stopt. Zeer tevreden
