AuskangPower Bank USB C 5000mAh Super Mini External Battery only 98g Lightweight with USB C Input & Output, Small Portable Charger for Smartphone, Bluetooth Earbuds, Camera, etc. (Black)

Almost gives an entire charge for a Samsung A40 so ideal for a top up if out for the day. Small and has tiny LED power indicators, comes in neat bag with short lead, very pleased as even if small a 10000 power bank us too heavy for a pocket, but this at 5000 is really very useful.

This power bank has a very useful form factor, sturdy build, and some clever design features. The capacity is somewhat less than stated though.Construction-wise, the device feels fairly solid. The case is made of plastic with a subtle texture but it's still quite slippery. The form factor is slightly unusual, being shorter but thicker that most similar power banks. The four LEDs that indicate remaining capacity are small and unobtrusive but easy enough to read. The USB-A and USB-C sockets are at opposite ends of the power bank; if using both at the same time, the design may make it a little difficult to fit the device in a pocket.I can confirm that the power bank supports pass-through charging; in other words, you can power a device from the USB-A socket while simultaneously charging the power bank itself through the USB-C socket.To determine the capacity, after a couple of full charge cycles I tested the output of the power bank by connecting a USB power meter to the USB-A port of the power bank, set for 1A draw. The battery was empty after 30456mWh or 6028mAh, which is somewhat less than the stated 6900mAh "rated capacity" indicated on the power bank. (Note that the stated 10,000mAh refers to the battery capacity at 3.7V, not the USB output capacity at 5V.) The capacity is enough for about two full charges on most larger smartphones.Overall, the power bank is a decent compromise between size and weight and capacity. I wish it could deliver the full stated capacity, but even if it overpromises slightly on that front, it's a good device.

Very small and easy to use. Great value and ideal to take out and keep handy. Highly recommendedUpdate review - bought this charger in September 2023 and already it not lasting very long. I use it to top up my iPhone 12 but it won’t even complete a full charge to 100%. It’s slower than it used to be and needs charging more often. Disappointed

I needed a portable charger for my iPhone to fit in my pocket for a gig, and this did the job exactly. Looks chunkier than other ones, but its so small and light that it fits really nicely in a pocket, or bag, and if you get a short cable to connect to a phone, charger and cable and phone can fit neatly in a pocket (well, man's pocket, not those women's pockets which fit exactly 6 atoms in them).It lasts for 1-2 good charges, so not for long term use without recharging the battery, but completely fine for emergency use or if your phones old and runs down halfway through the day. The little mesh bag it comes in is nice for keeping it from bashing against your phone or leg. However, you do probably need to get a cable to connect to your desired device, as this only has a cable to charge the battery from (to USB).

This powerbank is as small as i wanted it to be, and it stores enough charge to top up my iphone but the one i got seems to put out very little power and so takes much longer than i would like to deliver that charge. I find this offsets the advantage of the small size.

… of light use then it stopped working. Not worth the money.

I just got this small battery bank. It's a nice size and form factor. I can't speak to the capacity as I don't have the tools to measure that.Losing one star because the power button is small and concealed. It should be larger, raised, and a different colour.

Bought for using while out and about on the go. It is compact and easy to use. My only concern is that it is so small that the chances of me misplacing it are quite high! A nice problem to have!
