Charmast Power Bank, 26800mAh Slim Portable Charger with 4 Outputs & 3 Inputs, 15W USB C Battery Pack Compatible with iPhone 17/16/15/14/13/12 Pro Max Plus, iPad, Samsung, Tablet and more (Pink)

Honestly a niftly lil guy. Doesn't take long for a full charge. Quality finish and charges my ipad (second gen) super so that it extends its life from 45 mins to all day! ( This is what i bought it for). Basically saved me having to pay thousands for a new ipad. Would recommend you buy some port covers, there are a few -which is great! Lightweight and about the size of a standard mobil phone. So very portable and would likely fit a tonne of needs. Honestly well chuffed, i can see why people come back to give an updated positive review many years later. Great value for money and to be honest I'd happily buy this for other people!

Bought for my daughters bedroom in the pink and she loves it. She’s using for a cabinet in her room that has a strip light and no handy plug and it’s perfect. Very slim design and a lovely shade of pink. It’s very lightweight, so quick to charge up and lasts for hours, has a lovely carry pouch and easy to connect cables and looks really durable. Great price, will order another in white

Really handy to have this and is a decent price. Quality is ok and it charges pretty well , just takes a while to recharge. Overall no complaints and pretty satisfied

This power bank is excellent. It charges my devices quickly and holds a charge for a long time, which is very convenient for travel or busy days out. It’s compact, easy to carry, and very reliable. Definitely a great buy for anyone who needs extra battery on the go.

Literally take this everywhere with me! I bought one that I had for years but it accidentally got submersed in water and no longer worked, I have replaced with another one and don’t go anywhere without it! The charge lasts ages and you can charge almost anything on it! Doesn’t over heat and you can see how many bars of battery are left on the side with the lights! Not too heavy that I carry everywhere, also sleek thin design and not bulky.

Being a boomer, I grew up with brands I trusted completely, Sony, Technics, Panasonic etc. And now, all these years later, I am building up a list of new brands that deserve that same confidence. Charmast is one of those brands. I have ended up with a few Charmast products, and they have all proven to be dependable and reliable. No overheating, no battery swelling etc. My go-to high capacity power banks are INIU 140W 27000mAh. So I have a good benchmark, to compare the Charmast 26800mAh Power Bank to, and they are excellent! They cannot match the wattage of the INIUs, but they last just as long on lower wattages. The Charmast 26800mAh Power Bank does not have the fancy information display of the INIU, but the edge lights give you a rough idea on the remaining capacity. They are also oddly lovely devices to hold and use. They are wider and much thinner than the INIUs. They do not have the grunt to power a laptop. But they will certainly keep your iPad running during a transatlantic flight. Which is exactly what I bought the power bank for. And being so thin, it fits into the iPad shoulder case beautifully. I may even buy another, to give me weekend iPad goodness, without the need for any mains power. But once I am close to a convenient power socket, these Charmast 26800mAh Power Banks recharge in about 5 hours. Not super fast. But no slouch either. Highly recommended.

OK, the first thing to say is that this power bank is VAST. Please read the dimensions before you buy it. I confess I didn't and was amazed at how long and wide it is. It's slim, but about 195mm long and about 95mm wide. It's the exact size and shape of an 8" tablet in fact, only thicker and heavier. For me, that makes it awkward. I would have prefered a more chunky shape but not so wide and long. Another power bank I bought, with slightly more capacity and a little bit heavier, was much easier to carry, but this one I can't get my hand round it easily. I do not like the size and shape, although I didn't read the dimensions, so that was my own fault and it loses no stars for that. But despite the awkward shape I'm probably going to keep it because it works very well indeed. I've measured the input and the output voltages and current levels and it performs pretty-much as advertised. Importantly, at maximum current output the voltage doesn't drop much, and always stays above 5.0v Other power bricks I could mention suffer significant voltage drop at high current levels, and that will lead to slower charging. This one however manages tp keep the voltage up, and consequently keeps the Amps flowing at full speed. The other thing is that I wanted a power brick that supports pass-through charging. In fact I'm wanting to occasionally plug a tiny computer, like a Raspberry Pi, into its output, but also have the battery bank charging from the mains at the same time. I read that this one supports that function. Initially I thought that pass-through charging was not working, and in fact it wasn't working to start with, but then I noticed that two of the ports had little lightning synbols next to them, and I wondered if those were for the pass-through power. Turns out they are, although the manual says nothing about that. With a mains charger plugged in via the USB-C port (which has that lightning synbol), and the load - the thing being charged - plugged into the one USB-A port with the lightning symbol, pass-through charging seems to work perfectly. However, if things are plugged in via either of the other two USB-A outlet ports then it all goes haywire: the output voltage drops badly and most of the current from the wall charger just gets sucked into the battery bank, leaving very little left for the phone or whatever plugged in. So I reckon if you're going to use the pass-through power function you should not plug anything else in at the same time I checked this out using a USB power meter, so I could see the voltages at both inputs and outputs, and I am confident that the pass-through function works well. (I'm confident that the whole things worls well in fact. I hear what the manufucturers say in the answered questions here about how pass-through charging will work but it's not really advised because it can shorten the battery life, but it does seem to work perfectly, and I'm happy with that. It's not like I'll be keeping it plugged in like that 24/7. So overall I think this battery bank works very well indeed. I just wish it were not so vastly long and wide. I would have been happier with the same weigth and volume but in a small brick-shape, something you can hold comfortably in one hand. But the thing works so well that I reckon I'll live with the 8" tablet shape. (Now if you actually had an 8" tablet and you wanted to blutak this to the back of it to triple your battery life then that might work well!)

Bought this item in 2022. Since then it has not been subject to any physical damage and its usage has been very light side. So imagine my shock when I heard a noise and on investigating what made it I saw that the case had split. I dismantled the pack and the problem is due to one of the (two) flat battery packs beginning to swell. In order to reduce the risk of fire I have disconnected the batteries and safely disposed of them. Because of this defect and the danger it presents I cannot recommend this product, especially as there are others brands available.
