65W Power Bank, 20000mAh Portable Charger, High Capacity USB C *2 + USB A External Battery Pack, Travel Powerbank for MacBook Pro iPad Steam Deck iPhone 17 16 Samsung S25 etc

Great power bank Huge capacity and handy I use this to charge my drone and batteries as well as my phone and other gadgets. Rapid charging, great value for money, well designed handy easy to read percentage indicator and all round solid power bank It is heavy and bigger than my phone but that's a trade off due to how much portable power I require. Charging rate obviously decrease with the amount of stuff on charge but it can get my phone full in under an hour! Pair with decent rated cables and it's a winner. If you need a large capacity, cheapish, quick charging power bank this may be the one.

This powerbank is relatively big and bulky compared to others, but I think thats a sign of a genuine 20,000mAh capacity and possibly the ability to deliver 65W charging current. I bought this for a foreign family holiday. Using a smart phone all day to research local attractions; navigation; translation, etc drains the battery quickly. This powerbank can satisfy my Samsung phone for a 'Super Fast Charge', for a quick recharge before sharing it with someone else. Four of us could use it in a day and still not go flat. I recharged it using a 65W USB-C AC adaptor so it recharges quickly too. On the days where I don't expect to need this much battery, I'll take a lighter pack with me. But if you need a big pack and/or need 65W charging, then 100% recommended

I just got my INIU BI-B62 power bank and I've been really impressed so far. Here's what I like: + Fast Charging: It charged my phone super quickly! I plugged it in nearly dead and within an hour it was already at a good percentage. No more waiting around for hours for a full charge. Compact and Portable: It's surprisingly small and lightweight for its capacity. Perfect for carrying around all day. + Multiple Ports: Having both a USB-C and a USB-A port is great. I can charge my phone and another device simultaneously, which is a lifesaver when I'm out and about. + Built Quality: It feels really sturdy and well-made. The fabric mesh cover adds a nice touch and seems like it will protect the power bank from scratches. + Digital Display: The digital display is a great feature. It shows the remaining battery level clearly, so I always know how much juice I have left. I've only had it for a short while, so I can't speak to its long-term durability or how many full charges it actually delivers. But based on my first impressions, I'm really happy with this purchase. It seems like a great option for anyone who needs a reliable and portable way to keep their devices charged on the go.

After several technical tests with a USB multimeter, I can confirm the battery cells are high quality and hold their capacity very well. However, you might notice some 'erratic' behavior with the percentage display. For example, it might jump from 85% to 100% suddenly during a 20V charge, or stay at 1% for over 30 minutes while still outputting 25W. This isn't a battery failure; it’s a 'drift' in the Fuel Gauge/BMS software. The cells have more energy than the counter thinks! Tip: If your percentage seems off, do a full discharge until it shuts down and then a full 100% charge. This recalibrates the internal counter. Great hardware, just keep an eye on the software calibration. Keep in mind: often calibrations worn battery's cells faster. Technical Review: Excellent Cells, Conservative BMS Calibration I am uploading these photos to show a specific behavior of the Power Bank's charging curve. In the images, you can see the unit at 84% SoC (State of Charge), yet it is already behaving as if it were nearing 100%. Technical observations: Voltage/Current: The unit is negotiating 20V but the current is being throttled. Saturation Phase (CV): At 84%, the BMS (Battery Management System) is already forcing the transition from Constant Current (CC) to Constant Voltage (CV). Normally, this 'saturation' phase happens much later (around 90-95%). Thermal Management vs. Fuel Gauge: This suggests that either the internal Fuel Gauge has a significant drift (reporting 84% when the cells are actually closer to full) or the BMS is being extremely conservative with thermal management to protect the SOH (State of Health) of the cells. Conclusion: The fact that it can sustain high power delivery even at a reported 1% (sometimes for 30+ minutes) proves the cells are high-quality and have a massive energy reserve. However, the software calibration is a bit 'jumpy'. If you see it slowing down at 80% or jumping from 85% to 100%, it's just the BMS syncing with the actual cell voltage. Highly recommended for hardware quality, just be aware of the software's quirks.

I travel around the world a lot for work, honestly do not know how I lived without a power bank for so long. I bought one in 2025, and it has received constant use even when I have been at home. Going to the gym, but forgot to charge your headphones? That’s okay, this Powerbank will do that whilst you’re driving there. This particular powerbank holds enough charge to power numerous devices, and it does so at great speed. I have travelled from one side of the world to the other using this.

Just to add to my review below, after contacting the company I was given a full refund straight away along with a replacement power bank that works perfectly, thanks for the amazing service and assistance ! Arrived totally flat with no charge, upon charging it went from 0 to 99 % in 2 mins but would not charge any devices, left it on charge for another couple of hours but just shows 0% still, when connected to my phone the display just flickered showing 188%

Kupiłem powerbank Iniu, bo wcześniejszy model BI-B5 jest super. Mimo tej samej pojemności na etykiecie, efektywnie pojemność jest o połowę mniejsza.

The power bank did not charge according to specifications so I returned it. Was contacted relatively immediately by inui's customer service and they sent a new one which arrived the following week. Although I was unhappy with the first one, I am very happy with the new one and very good customer service.

J’ai testé cette batterie INIU avec différents appareils (smartphone, tablette et ordinateur portable), et elle tient toutes ses promesses. La charge rapide en 65 W est un vrai atout : mon ordinateur se recharge sans difficulté, mon téléphone atteint plus de 50 % en une trentaine de minutes et ma montre se charge également. La capacité de 20 000 mAh permet plusieurs cycles de charge, ce qui la rend pratique pour les déplacements ou les journées sans accès à une prise secteur. La présence d’un port USB-C en entrée et en sortie la rend très polyvalente, et la compatibilité avec de nombreux appareils est un vrai plus. Côté design, le format reste compact pour une batterie de cette capacité, et la finition est correcte. Après plusieurs utilisations, je n’ai pour le moment pas noté de surchauffe. En résumé, c’est une batterie fiable, performante et bien pensée, idéale pour ceux qui cherchent une solution de charge rapide et durable.

Buena duración y potencia suficiente para cargar un ipad o macbook. Funciona a la perfección después de más de un año de uso constante y varias caidas al suelo.

Erg blij met deze aanschaf. Laad erg snel op, en doet wat je van een powerbank verwacht.
