Fab! Wide! But Fab
love this! had to return my original one after a year as the fast charge port stopped working, amazon happily refunded me and i bought another as it is so convenient and comes wit me everywhere. highly recommend, veyr nice quality, it is wider than your phone, think 1 and a half size of your phone lenght and width and youll be on the right track, but it does fit in my bags and pockets so it works for me. i take it everywhere i go!, can normally charge my Redmi Android at least 3 times. keeps my phone going all day through to next morning!

A Portable Powerhouse, Fully Charged
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.

The Charmast 26800mAh Power Bank is a superb compromise of price, capacity, power and recharge speed
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.

Better than Anker! 3 months review
I'll be bold and say this is much better than my (as of writing) £50 on Amazon Anker portable charger which I've had for a number of years. It's really easy and simple to use. Has all the ports you want although it does lack one USB c port which is a shame since that's the most common one in 2024! It charges relatively quickly (6 hours I had for a full charge from being flat), performs amazingly well and charged my Google Pixel 7 Pro real quickly. Sadly, the main drawback is it doesn't say what the percentage of charge is for the power bank, just a few bars here and there. To know it's charging the phone, there is a small display indicator thing on the top left of the charger which will basically be on to say it's charging. It's a simple display in truth and the lighting could definitely be improved. But that's me being picky, the bolts and the nuts of it all is this is a great portable charger. Doesn't feel heavy to me at all (like a normal phone) far from being able to just slot into your pocket due to its width, but slim to make it feel easy on your hands. Can easily take it with you in the hand luggage in the airports too without much concerns. Highly recommended, and without doubt value for money (£20)! Pictures included.

Brilliant power bank. Highly recommended
Excellent way to ensure you’re always charged. It has Micro in, Lightning in, USB C, and 3 USB type A. Charging of the power bank is very fast. Charging of your devices when you need to transfer some juice is also very fast. The MOST important thing for me when I was looking for a power bank was the reassurance that I was buying something that I didn’t have to worry about exploding when being used. I have 100% confidence that this power bank is safe. It’s worth paying for this piece of kit because not only does it hold an incredible amount of charge, it’s extremely versatile and has a good, solid build. The unit displays all the safety standards that it has met for sale in the UK/EU.

Technische Daten Also, auf dem Papier klingt die Charmast Power Bank schon nach Königsklasse: satte 26 800 mAh, drei Eingänge (Micro-USB, Lightning, USB-C) zum Auftanken und vier Ausgänge für eure Geräte. Schlanke 14 Millimeter dick und trotzdem mit Power-Delivery-Unterstützung für blitzschnelles Laden. Vollgeladen braucht das Dickschiff allerdings einige Stunden mit 5 V/2 A – da hört man schon mal das leise Surren. Gewicht? nicht federleicht, aber hey, Kapazität hat nun mal ihren Preis. Design und Haptik Wenn man sie aus der Tasche zieht, fühlt sich das Teil an wie ein kleines Tablet – kantig, aber mit abgerundeten Ecken, die angenehm in der Hand liegen. Die matte Oberfläche verzeiht Fingerabdrücke und rutscht nicht sofort durch die Ritze eurer Couch. Die Status-LEDs blinken dezent, nicht zu grell, so dass man nicht nachts vom Leuchten gestört wird. In meinen drei Farben (Schwarz, Weiß, Pink) sieht sie immer noch stylish aus, kein billiges Plastik-Gefliege. Manchmal hat man fast das Gefühl, sie sei ein rebellischer Kamerad, der sich weigert, langweilig zu sein. Alltagstauglichkeit Ob auf Festival, Wochenendtrip oder im Büro-Marathon: Die Charmast lagert drei volle Smartphone-Ladungen und eine halbe Tablet-Füllung. Ich habe sie versehentlich in der Hosentasche gedrückt – ups – und trotzdem ist nichts kaputtgegangen. Mal schnell fünf Minuten angeschlossen und schon kriegt das Handy genug Saft für ein Insta-Video. Pass-through-Charging funktioniert wie ein Schweizer Taschenmesser: Während sie selbst geladen wird, kann man zwei Geräte gleichzeitig betanken – perfekt, wenn eure Kumpels rumschnorren. Kleinere Macken: die Kabel-Stecker sind manchmal fummelig, aber das ist Jammern auf hohem Niveau. Ladeleistung und Geschwindigkeit Hier merkt man, dass nicht alle Powerbanks gleich sind. Die Charmast haut mit 15 W raus, bei USB-C sogar mit Quick-Charge-Tech und 9 Volt-Strom. Klar, man kann kein Wunder erwarten, aber im Vergleich zu Winzlingen mit 10 000 mAh ist das schon ’ne Ansage. Einmal vom Sonnenuntergang bis zum Frühstück angeschlossen, ist sie randvoll. Wenn’s eilt, reichen 30 Minuten für 20 Prozent extra – nicht übel, oder? Kurz und knapp ✅ Beeindruckende 26 800 mAh Kapazität für mehrere Full-Ladungen ✅ Vier Ausgänge und drei Eingänge für maximale Flexibilität ✅ Schlankes Design mit nur 14 mm Dicke trotz Power-Delivery ✅ Bis zu 15 W Ladeleistung, USB-C mit Quick-Charge ✅ Pass-through-Charging zum gleichzeitigen Laden ✅ Robuste Bauweise, griffige Oberfläche, wenig Fingerabdrücke Fazit Am Ende des Tages hat mich die Charmast Power Bank echt überzeugt. Sie vereint massiv viel Kapazität mit einem überraschend schlanken Profil und quetscht trotzdem ein Schnelllade-Feuerwerk hinein. Klar, ein paar Gramm mehr auf der Waage, aber wer unterwegs nicht ständig nach Steckdosen suchen will, nimmt das gerne in Kauf. Die praktische Pass-through-Funktion reiht sich nahtlos in meinen Gadget-Alltag ein wie der perfekte Dreh im Film. Einzig das Fummeln beim Kabeleinstecken nervt manchmal, aber hey, nobody’s perfect. Wer also einen treuen Energielieferanten sucht, der nicht sofort schlappmacht, liegt hier goldrichtig. Danke, Charmast, für den Extrakick Saft, der mich nie im Stich lässt.

So I did just pull this out of the box about 20 minutes ago but I am already impressed. I have had many power banks... Many. And this thing is a beast!!!! I have no doubt it will fullfil all my charging needs other than a laptop. I'll have to try it and get back to you. I use power banks for my note nine, Samsung watch, buds and tablet at least 3 times a week. This power bank is double the size of my other ones but still thin and nicely designed. It is heavy but what do you expect when ordering a large capacity power bank? Very nice I'm hand feel. I have connected my phone to it to make sure it works... And it does. The battery indicator light shows fully charged. I can already tell I am only going to be carrying one power bank from now on. If something goes wrong with the device I will update but I don't think that's gonna happen. The battery capacity is also labeled on the device which is another sign that this isn't a knock off! Very impressed just pulling it out of the box! 2 years later ….. I still absolutely love this power bank! It has never let me down. I charge my phone tablets and watch off it!

Excellent power bank. Used it to charge my Google Pixel 2 while traveling. The USB C supports fast charging which is great. The power bank is quite big and will not fit in a pocket so you will need to carry it in your day bag(see picture attached compared to a Google Pixel 2 phone) In terms of weight feels twice as heavy as a Pixel 2 phone. Also, you can use it to charge multiple devices.

重さがけっこうあるのであまり持ち歩きたくないですが、数ヶ月放置してもまだ放電されていません!もう販売されてないのかな。いい物って消えていきますね。

Tengo varias powerbanks de este estilo, pero buscaba una de gran capacidad y que a la vez no ocupara mucho espacio, para llevarla en una bandolera, y me decidí por esta, ya que me llamó la atención su delgadez. Decir que la primera impresión ha sido mucho mejor de lo esperado. Me esperaba una powerbank de plástico, sin más, pero cual ha sido mi sorpresa al tocarla, es plástico, sí, pero un plástico muy muy agradable y suave. Es difícil de explicar, porque no es goma, ni plástico típico de otros aparatos, tiene un acabado suave al tacto que la hacen muy muy suave. Hago hincapié en esto porque realmente no había tocado algo así antes, me ha sorprendido para muy bien. Y tengo experiencia con infinidad de aparatos electrónicos de todo tipo. Por lo demás, nada que no se vea en las fotos. De tamaño es grandecita, y pesa un poco, dada su gran capacidad, pero lo compensa, y mucho, su delgadez. En mi bandolera que llevo siempre de viaje, ni se nota, no abulta nada. También es un puntazo la cantidad de puertos que tiene, y su botón, junto a sus 4 leds para comprobar el nivel de la batería. La he estado probando y he podido cargar al completo un ipad pro y aún me quedaban 3 puntitos de batería de la powerbank. Si buscas una powerbank de gran capacidad y que ocupe poco, no encontrarás muchas más que sean tan delgadas. La recomiendo totalmente.
