Excellent Power Bank
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

Good power bank for those on the go
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.

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.

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!

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.

Charged my s23 ultra 3 times fully with a little more juice to spare
Firstly I didn't have high hopes for this powerbank at all. I wanted to buy an anker powerbank because I know they are the best brand but they're just too expensive so I settled with this. Before this I had a 20,000mah baseus powerbank which used to charge my phone twice but after just a few weeks of use it broke and would only charge my phone once. That cost me 20 quid and baseus wasn't helpful with returns so I was stuck with a heavy rubbish powerbank. I bought this and immediately loved the design. I like how you can charge with almost any cable be it usb c, lightning or even microusb. I like that it was thin and quite light but the weight made me suspect that it might have lied about it's capacity (thankfully this wasn't the case). Fully charged the powerbank up and drained my phone to 1%. Charged my phone up and over the course of 3 days I used this powerbank to charge my s23 ultra from 1% to 100%. It managed 3 full charges! This shows that the capacity of 26800mah is true. You need to remember that the 26800mah doesn't mean you'll get that much power out of it (even on an anker powerbank). You need to take into consideration the power factor and also that the phone charges at 5v, not at the 3.7v needed to achieve 26800mah. So after doing the calculations I was expecting between 3-4 full charges on my s23 ultra and the fact that it was correct proves that the capacity isn't a lie. I also like that it comes with quick charging so I was able to fully charge my phone in just 1 hour and 20 minutes. If you use the slower USB A port to charge your phone then you'll get more energy out of it because you the powerbank sacrifices some mah for speed when you use quick charge. Overall, fantastic product and I'm very happy with it. I hope it keeps it's capacity unlike the baseus powerbank that I got before. If I don't update this review it means that it's still working perfectly. If it dies or gives me any issues I will update this review. Thank you charmast!

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.

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.
