Anker Power Bank, 347 Portable Charger (PowerCore 40K), 40,000mAh Battery Pack with USB-C High-Speed Charging, For iPhone 13 / Pro/Pro Max/mini, Samsung Galaxy, iPad, AirPods, and More

This charger holds an incredible amount of power and can charge phones / laptops quickly. It is very heavy like a brick so has limited portability. Fine in a backpack but not a pocket. Overall, very pleased with this purchase.

This power bank is great, but please be aware that it is too large to be allowed onto aircraft. There was also a delay caused by UPS due to having to fill out a hazardous cargo form (the limit for aircraft is 100Wh = 20,000mAh at 5v). I'd strongly recommend this for festivals / camping / etc.

These do take a considerable time to charge even with a 120 watt rated Anker charger and cable. I tried using the charger for my internal battery powered, high wattage portable speaker on an overnight charging, as it is a USB C charger; strangely it actually discharged from half capacity to zero even though the charger was plugged in! There is clearly a very high threshold supply wattage needed for charging to commence and this is something anyone considering one of these should be aware of; as it means the purchase of a high output USB mains charger along with a cable equally capable of allowing high value currents to flow. Therefore it is not just the price of the powerbank itself you have to consider but also the additional cost of a suitable charger. Word of advice regarding all Lithium battery powered items: The deeper the level of discharge IE between 40% the less recharge cycles you have, therefore you will end up replacing such items more quickly. As these power banks have a twelve LED status indicator it is best to start recharging around 5 or 4 LEDs as 3 is about 25% remaining and at that you are life limiting the cells in this product.

I bought this primarily to use in with my digital sheet music setup. It charges 2* 12.9" iPad Pros, as well as charging my phone and powering a usb fan. This setup I use to display sheet music whilst playing in a concert band. So far, I've managed to run it out once. Charged it up fully, then used it to run the power for both iPads for 3 * 2 hour playing sessions, which both screens on all the time, and both iPads needing to be charged. When the power bank ran out, 1/2 way through the 3rd session, it had already charged both iPads enough to last for the rest of the evening with ease. I would not recommend for charging a laptop, but two iPads a Phone and something else, it can take in it's stride easily. Not sure if you can take this on a plane, so that will limit the travel opportunities. Other than that question, it works like a charm.

Works well, charging devices quickly. It’s built very well, but is susceptible to scratches. The battery life is impressive and I find it a great value for money.

I have this and also an anker 20,000mah power bank. Comparing them side by side to power devices they are almost identical in their capacity. Both charge my z fold 3 only 3 times. Id expect the 40,000 power bank to have twice the capacity as the 20,000. This cant be returned for a refund ( 3 weeks old) as its a power bank and the seller is just saying its down to the internal components and how they are inefficient. Personally i wouldnt spend 3x the amount on this one and opt for a 20,000 power bank instead

An amazing product. Powerful; quickly charges my phone. Lasts a very long time before I have to recharge the power bank itself, and only takes overnight when empty.

The product itself charges devices quickly but it is big and heavy and not really suitable to be carried round as a portable device. Tried to return it but the product comes with a no returns policy which was disappointing.

Works great as a brick! It is heavy! It also charges your devices... many, many times!

It’s good product using since 1 year now.

Biraz yavaş şarj ediyor sanırım kapsamlı olarak deneyemedim ancak anker her zaman iyidir şaşırtmaz :)

Diese Powerbank ist einfach super. Die Tablets der Kinder, plus alle Handys im Haushalt, können mit dieser Powerbank eine Woche geladen werden.
