Charmast 26800mAh Power Bank USB C Battery Pack Portable Charger USB C Slim Type C Battery Bank with 3 Input & 4 iSmart Output compatible with Smartphones Tablets and More (Black)

The Charmast Power Bank arrived in a no-frills, practical package. The delivery was prompt, and the box, though simple, was sturdy and did an excellent job of protecting the product. Unboxing revealed a sleek, slim device that felt both professional and durable. The look of this power bank is minimalist and sophisticated. The slim, black design is understated, with a smooth, matte finish that gives it a high-end feel. It’s a very clean and modern aesthetic that won't look out of place in a business meeting or a casual coffee shop. The multitude of ports—three inputs and four outputs—are neatly arranged and well-labeled, a testament to the product’s focus on versatility and user-friendliness. When you pick it up, the power bank has a solid and surprisingly lightweight feel for its large 26800mAh capacity. It's thin enough to slip into a bag or a large pocket, and the smooth surface feels comfortable in your hand. The ports are securely fitted, and the cables plug in with a reassuring click. It feels like a device that's built to withstand the rigors of travel and daily use, and its build quality inspires confidence. I’ve used this power bank for a wide range of tasks, and it has become an indispensable travel companion. Its colossal capacity has been a lifesaver on long flights and multi-day trips where power outlets are scarce. It’s perfect for charging my smartphone and tablet simultaneously, and I've even used it to keep a small portable speaker or headphones running during an outdoor event. Most recently, I've discovered its perfect use for powering my Lego lighting kits, giving me a reliable and long-lasting power source without having to rely on multiple batteries. The ability to charge up to four devices at once is a fantastic feature, making it the central hub for all my electronics. This power bank is a powerful and reliable solution for anyone who needs to keep their devices charged and ready to go, no matter where their day takes them.

I’m really impressed with this power bank. The 26800mAh capacity is a total game-changer for keeping my devices charged throughout the day without needing to hunt for a wall outlet. It’s well-built, charges my gear quickly, and is honestly essential for travel or long days out. Definitely worth the purchase!

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

One of the best powerbanks I've ever owned. The slim design is perfect to slip into my tackle box for fishing. It charges all devices in no time. Absolutely fantastic

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.

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!

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!)

Charged it to full, and when I plugged in my phone it indicated it’s a ‘Slow’ charger. I have yet to use it to get my phone to full because it was so slow that after waiting an hour with barely any change I stopped trying. Despite this, its battery has already gone down to 2 bars out of 4. So I haven’t even managed one full charge out of it before it has gone down to 2 bars, it’s worthless.

Franchement , agréablement surpris .. bonne autonomie , peut d’encombrement là où d’autres ont la diminuions d’une brique .. et le prix ne gâche pas le plaisir ..

2019年購入、7年目です。 3年目くらいで表面のベタつきや汚れが目立つようになりましたが、アルコールで拭いてベビーパウダーを振ることで復活しました。年1回くらいお手入れしています。 今年に入って残量のランプがつかなくなひましたが、充電自体は問題なくできます。残量が分からないのは不便ですが容量、スリムさ共に使い勝手がすごく良く、壊れるまで愛用したいと思います。

Ich habe diese Powerbank jetzt schon gute 2 Jahre in Benutzung und liebe sie. Bisher hat sie mich nicht im Stich gelassen und mir sogar mehrere Tage autark im Wanderurlaub ermöglicht. Sie hält extrem lange, im besagten Wanderurlaub für Handy und Apple Watch gute 4 Tage, darf gerade noch so im Flugzeug mitgenommen werden und ist auch ziemlich schmal. Für eine Powerbank ist sie natürlich ziemlich schwer, aber wenn man die Leistung berücksichtigt, dann ist dieser Nachteil auch hinzunehmen. In Zukunft wären vermutlich mehrere USB-C-Eingänge anstatt USB-A besser, wenn man dem Trend mit USB-C folgt. Sehr praktisch ist aber auch, dass sich die Powerbank mit USB-C, Lightning und Micro-USB aufladen lässt, das gibt einem, gerade wenn man unterwegs ist, viel Flexibilität. Fürs Wiederaufladen braucht sie sehr lange, aber 26700mAh sind ja auch nicht gerade wenig Kapazität. Eine absolute Kaufempfehlung für jeden, der für längere Zeit ohne eine Steckdose auskommen muss oder nicht jeden Tag nachladen will. Kleiner Bonus: Das Rosa ist wirklich schön!

Es una maravilla, en mi familia la usamos todos, he comprado como 4 de estas porque dura muchísimo sin usar (no se descarga), se pueden cargar varios dispositivos, viene con el cable de carga y una bolsa protectora muy útil, y aun a pesar de ser grande, al ser fina es cómoda para llevarla en el bolso o mochila. Nunca viajo sin ella!! Quizás la única pega que le pondría es que una vez descargada, tarda mucho en cargarse al 100% (toda la noche), pero bueno, es normal para esta capacidad. Buenísima relación calidad-precio

大容量タイプの中では群を抜いて質とコスパが良い商品でした！ デザインに安っぽさは無くマットな手触りで清潔感があります。 4本それぞれの出力で同時にMAX充電が可能の様なのでとても便利です。 ・実容量 満タンから残り充電10％のiPadpro10.5(約10000mAh)を充電してみました。 結果はランプ4つから一つ消えただけでした。 充電可能な実容量は20000は軽く超えている事が伺えます。 ・発熱 驚いたのは発熱の少なさ！ 同じく18WのPD対応のアンカー製品ではバッテリー本体の端(基盤部分？)がカイロ並みに熱くなってましたがこちらの製品はほんわか熱くなっている程度でした。 無駄な電気抵抗が無いと言うことなので素晴らしいです。 ・携帯性 容量が容量なだけになかなか重たいですがこの容量だったら軽い方です！ 薄いので鞄に入れる際に勝手が良くてすごく気に入りました。 ・充電速度 これは記載通りの出力なので満足です。 同時充電でも4ポート各々最大出力で充電出来て文句なしです！ ただ、PD30Wだったらもっと最高でした！
