2 Technologies to Break Size Limits 
High-Density TinyCell
Same battery capacity as an ordinary one while 20-30% smaller and thinner profile.
HyperStack Architecture
With more compact circuit stacking, the length of the power bank can be reduced by 15mm without sacrificing power or performance.
1 USB-C Output
2 USB-C Input
3 Smaller Yet Stronger
What’s the Difference Between 65W, 100W, and 140W Laptop Power Banks?
65W: Great for lightweight laptops like MacBook Air；100W: Covers most high-performance laptops.；140W: Needed for ultra-high-performance laptops and full-speed PD 3.1 charging.
Choose a power bank based on your laptop’s max input and daily workload.
Can a Laptop Power Bank Damage My Laptop Battery?
No, if you pick a high-quality, compatible power bank with proper voltage regulation and USB-C PD support. Low-quality or unstable power banks can wear the battery over time. Always choose certified power banks with protections.
Why Does My Power Bank Provide Fewer Charges Than Expected?
External batteries typically deliver 60%-70% of their rated capacity.
30%-40% is lost to heat from voltage conversion and circuitry, which reduces the number of full charges for your device.
How to Calculate the Possible Number of Charges?
Formula: (Rated capacity × 65%) ÷ Device battery capacity ≈ Number of Charges.
Example: (20000mAh × 0.65) ÷ 3692mAh ≈ 3.5 charges for iPhone 17.
Does It Support Pass-Through Charging?
Yes. The power bank supports pass-through charging, allowing you to charge the power bank and connected devices at the same time.

Same great quality and convenient USB-C cable
Smaller but just over 1” thick. Nice display showing % charging and remaining. It powers a MacBook Air M series just fine.I love that it has a built-in lanyard holding a short USB-C cable pretty cool and handy.Only one of the USB-C ports is for charging.USB-C x2 (65watt, 36watt)USB-A x1 (18watt)I have a 100watt INIU power bank that is two of these in length. Great quality and performance so far which is why I bought this smaller one.

Works well, holds a good charge
Charges a lot of things before it runs out, takes a while to recharge but nothing abnormal. It does seem to charge as a fast charger, so I wouldn’t use it every time because that’s not good for your battery. It’s got some weight to it, but it will fit in your purse if it’s at least a medium sized purse. Don’t leave it in your car, I feel like that’s something everybody should know. Just don’t ever leave these things in your car.

Affordable & light
Good power bank. The size is small, handy, and easy to carry. Fast charging is amazing. highly recommended.

Highly recommend, super durable, high capacity, and fast charging!!
Exactly what I wanted. Fully charged, it charges my Samsung Note 20 2-3 times or my Mac M1 once. It takes couple hours to charge, but I just plug it in before I go to bed. Love the design; the screen stays fingerprint-free. I dropped it a couple of times from 4-ish feet but it didn’t break; the side casing popped out but I just pushed it back in – good as new. It is heavy, but that’s understandable given the capacity. With this, I don’t have to worry about finding a wall socket if I want to use my laptop in a cafe, library, or traveling (especially on flights). It charges my phone noticeably faster than my regular phone charger (roughly 30% of battery in 10-20 minutes). It gets warm when you are charging the power bank, but not when its charging your devices. The dongle it comes with is super durable too, I haven’t noticed significant wear with it yet after using for a couple of months. I don’t think it’s compatible with the China’s new power bank regulations though, so don’t bring it on your luggage if you are traveling to China. Overall, highly recommend!!

Works well output not sure..
Cons: 65 watt output is highly questionable. My laptop charger is 65watt and charges it fast while using. This charger using the correct port rated for 65watta barely charges during use. It does keep it at where it is. If it’s at 80% charge it will stay at 80% for the entire time. If I had to guess the actual output I would say 35watts. It is just enough to hold the same charge percentage the laptop was at when plugged in for 4-5hours. I have tried 240 watt rated USB C cables it does seem to charge a hair faster and with this will slowly charge. It is still no where near as fast as the 65watt wall charger that comes with the laptop.Pros: even though it does seem to have enough output to charge it more while using it is just enough to not lose any laptop battery and continue to use the laptop for almost 5 hours! Which is extremely impressive my laptop alone maybe gets 2.5 hours. So this adds about 4.5-5hrs to that giving up to 7 hours of constant use which is awesome.To sum it up this charger with is capacity was almost had the price of Anker and I green. It works great for the price . I am confident Anker and Ugreen do charge at the advertised 65watt. I am confident this one does not do that. It is still fast enough to work fine with you laptop I suggest plugging it in when your laptop is at 80% or higher. It will hold that level for the entire time you use it.

The Best Portable Charger for Every Need!
I’ve tried many power banks before, but INIU has quickly become my go-to brand. Their 20,000 mAh, 65 W power bank is the most powerful, compact, and reliable charger I’ve ever owned.Charging Ability: With 65 W output, it enables me to charge almost all my devices at their maximum charging speed. For my Samsung S22 Ultra, it takes about an hour to charge back to full. I mainly start charging my phone again throughout the day when it’s around 30% and to get up to around 80% again with this portable charger takes about 30 minutes and only takes away around 15 to 20% of the portable charger’s full capacity. I also bought this charger to help charge my Rog Ally, but I haven’t tested it yet. I estimate it could charge the Rog Ally to full again pretty quickly, but use up around 70% of its power. I can confidently say though I can get multiple phone charges no problem without worrying this will run out of battery with 20,000 mAh.Size: I love the size of this mini portable charger. Even with 20,000 mAh, it’s compact enough to meet airline carry-on requirements and fits neatly into my backpack or travel pouch without feeling like dead weight. It is around half the size of my first Inui charger that I’ve bought, which is the normal size. I feel like this one is small enough to also slip into your pocket, no issue.Design: The build feels premium and durable. I like the easy-to-use on-screen display, which works by pressing the power button once. A big thing I like about this one in particular is the cord that is tied to the side of the device. This cord makes it so convenient to charge my phone when I don’t have any wires with me on hand. The cord on the side of the device is USB-C and supports up to 100 watts.If you need one reliable charger for a phone, laptop, or travel emergencies, INIU is where it’s at. I’ve used cheaper brands, but nothing comes close to this perfect balance of speed, capacity, and portability. It’s absolutely the best power bank I’ve ever owned.

Great Little Power Bank
Took this with me on my 27-hour flight. It kept my laptop, tablet, and phone all perfectly charged at 100% the entire time. It’s a great size for a carry-on, and the indicator makes it easy to use. It’s not as heavy as my previous power bank of the same size. I’ll probably get another so that I have a backup since they are a great price.

このモバイルバッテリーのセールスポイントは「65W出力」「20,000mAh」「最小クラス」です。65W出力できる容量20,000mAhのモバイルバッテリーはもっと安価な製品がありますので、ポイントは「最小クラス」かどうかになります。当方で重さを計測した結果、323gでした。持ち歩くことを想定して、これが重いと感じるか、軽いと感じるか意見が分かれるところです。ちなみに複数ポートを同時使用した場合の最大出力について商品紹介には記載がなかったので載せておきます。USB-C1単独使用 : 65WUSB-C2単独使用 : 35WUSB-A 単独使用 : 18WUSB-C1 + USB-C2 : 45W + 20WUSB-C1 + USB-A : 45W + 18WUSB-C2 + USB-A : 合わせて15WUSB-C1 + USB-C2 + USB-A : 45W +15W(C2とA合わせて)このバッテリー購入を検討されている方の参考になれば幸いです。

Idéal pour changer plusieurs appareils en même temps . Je vous conseil d’acquérir le chargeur qui va bien avec

Diese Powerbank gefällt, vor allem durch kompakte Ausmaße und gute Leistungswerte. Zwar kann auch INIU nicht zauberen und das was in der Höhe und Breite gespart wird, findet sich zum Teil als Tiefe wieder, aber vergleicht man das ganze mit älteren 20.000mAh-Powerbanks, dann stellt man schon ein etwas niedrigeres Gewicht und kleineren Platzbedarf fest. Diese Gehäuseform empfinde ich als handlicher und einfacher in Taschen zu verstauen.Ansonsten bewegen wir uns Ausstattungstechnisch auf Standard-Niveau, aber eben auf gutem und zeitgemäßen. Es gibt keine überflüssigen Kinkerlitzchen, sondern ein gut lesbares Display, einen Button um dieses zu aktivieren und 3 Anschlüsse, 2 x USB-C und 1 x USB-A.Hier überzeugen vor allem die auf den heutigen Alltag zugeschnittenen Werte. Der erste USB-C-Anschluss ist der stärkste, er darf bis zu 65W ausgeben und wird mit bis zu 45W geladen. Beide Werte, wie auch die Kapazität, kann ich nach 2 Test-Zyklen erst einmal bestätigen. Am zweiten USB-C-Port gibt es immerhin noch 36W Output und am dritten USB-A Port finden ältere Geräte mit bis zu 18W ihren Strom-Happen. Handy und Tablet gleichzeitig laden geht so problemlos, mit einem QI-Dock Uhr und Handy gleichzeitig laden ebenso.Das Teil ist also voll reisetauglich und das bestätigt auch das robuste und Ecken- und Kanten-lose Gehäuse. Es passt aber auch recht gut in eine Hand- oder Jackentaschen, und die verschiedenen erhältlichen Farbvarianten sind ohnehin ein hübscher Bonus.Im Lieferumfang gibt es noch einen kleinen Pouch und das obligatorische USB-Kabel, beides in brauchbarer aber nicht herausragender Qualität.Diese Powerbank ist eines der Produkte die mit Einfachheit in der Benutzung und der Reduzierung aufs Wesentliche überzeugen, indem sie eben dies kompromisslos und in sehr guter Qualität umsetzen. Kaufen, Auspacken, keine Anleitung lesen, und einfach benutzen eben.

This Iniu Power Bank comes in a range of great colours (I went for the Yellow one), is compact and comes with a drawstring net carrying pouch, a USB ‘C’ to ‘C’ charging cable and small set of instructions.It has an impressive 65W output and 20000mAh capacity which is really useful to have available when you need to charge devices in an emergency or whilst away from any other means of charging them. It has clear display which shows the current percentage charge level and has both USB ‘A’ and ‘C’ power output ports (2 x USB ‘C’ 1 x USB ‘A’ – one of the USB ‘C’ ports is both input – to charge the powerbank itself – and max output to provide the full 65W to one device). Charging multiple devices will divide the output depending on how many devices you need to charge (max. 3 if using all the ports).It isn’t lightweight but not as big (fits in the palm of your hand) or as weighty as many other power banks. It should fit easily fit into a small bag or large pocket e.g. a coat if required. The build quality feels very good and robust and does not feel cheap or poorly made. There is no mention of water resistance (no IP rating is quoted) so it is unlikley to stand exposure to moisture which is a bit odd for something you’re going to carry around, so it’s worth bearing this mind when taking it out and about with you and keep it in a water resistant bag or similar.Overall it’s a great piece of kit for the money when you need to charge device(s) – which includes Laptops – in an emergency and is great value for £48.99 at the time of writing. Definitely recommended.

Buscaba un Powerbank de buena capacidad y con potencia mayor de lo habitual en el mercado, que son 22.5W y que fuera suficiente para cargar un portátil. El producto es una mini batería externa con potencia de 65W y capacidad de 20.000mAh, mucho mayor de lo normal, de la marca INUI. Incluye una bolsa de transporte con tejido en malla transpirable y un cable USB-C a USB-C de carga corto que soporta hasta 100W.Experiencia de uso:Recibo el pedido del modelo mini P62-E1-YE en color amarillo (hay disponibles también colores negro, blanco, naranja y rojo). Es realmente tamaño mini, con longitud de 10,5 cm, anchura de 6,5 cm y grosor de 3 cm. Se anuncia como el más pequeño del mercado y tengo que decir que, hoy día, con esa potencia y capacidad, seguramente lo sea. Tampoco pesa excesivamente. Con la carga al 100% pesa 325,3 gramos.Proporciona 3 puertos de salida, un USB-A a un máximo de 12V/1.5A~18W, un USB-C a un máximo de 12V/3A~36W, y otro USB-C doble, de entrada y salida, con un máximo de salida 20V/3.25A~65W y máximo de 20V/2.25A~45W de entrada.Dispone de una pantalla con información del % de carga en la frontal y en la trasera lleva la tabla de salidas de los puertos cuando se usan conjuntamente:- USB-C1 + USB-C2 dan 45W y 20W respectivamente para una potencia máxima acumulada de 65W.- USB-C1 + USB-A3 dan 45W y 18W respectivamente para una potencia máxima acumulada de 63W.- USB-C2 + USB-A3 está limitados A 15W compartidos.- USB-C1 + USB-C2 + USB-A3 dan 45W el primero y 15W los otros dos, para una potencia máxima acumulada de 60W.¿Qué significa esto?Esencialmente, que solo se puede usar el puerto USB-C1 para cargas de portátiles o carga rápida en móviles (limitadas a 45W con USB-C) y que conviene usar los puertos USB-A3 Y USB-C2 para cargar dispositivos pequeños que no necesiten gran potencia.El powerbank se carga a buena velocidad, usando la máxima potencia de un adaptador de corriente de 200W que soporta PD 3.0 con PPS con máximo de salida por puerto USB-C de 63W (21V/3A). La carga de la mini batería se realiza con 20.2V/2.37A a unos 48W constantes, sin sobrecalentamiento en ninguno de los dos extremos. Se carga el 100% en menos de dos horas en estas condiciones. Si no disponemos de un cargador de potencia, tardará más tiempo.Respecto a las pruebas de uso del powerbank, utilizo un Xiaomi Redmi Note 12 5G Pro+ y el powerbank carga mejor que varios cargadores de 30-40W que ya he probado, alcanzando cargas rápidas en torno a los 30W constantes. Lo pruebo cargando un portátil moderno con puerto de entrada USB-C y funciona muy bien, con carga media en torno a los 40W. Muy buen resultado, perfecto para lo que quiero.Sobre la portabilidad; es comodísimo. Se puede llevar en casi cualquier bolsillo de una mochila y, si disponemos de puerto USB integrado en la mochila, permitirá cargar cualquier dispositivo sin problema, dependiendo de la calidad del cable que lleve la mochila. No pesa excesivamente y el tamaño es ideal para el transporte.Consejos de uso:- Si se guarda en una mochila para usarlo para cargar, escoger un bolsillo en que vaya bien sujeto y que tenga buena transpiración.- Si ves que se calienta mucho al cargarlo, recomiendo utilizar para la carga un adaptador de corriente de menor potencia, como 30W-40W, aunque tarde más en cargar la mini batería. La temperatura es el gran enemigo de la duración de las baterías de litio.- Asegúrate de disponer de cables USB-C o USB-A que soporten las potencias que necesita el powerbank.Puntos fuertes:- Alta potencia y capacidad de batería.- Admite Samsung super fast charging 2.0.- Soporta PD3.0.- Garantía iNiu Care de 3 años, además de soporte técnico de por vida.Puntos débiles:- El único puerto de entrada de energía para cargar el powerbank es USB-C.Resumiendo: Mini batería/powerbank de alta calidad con capacidad para varias cargas de teléfono móvil y potencia suficiente para cargar un portátil moderno. Muy recomendable.
