Even without the app, the screen display is informative and easy to read. Do your homework before buying and I'm sure you will agree with me; it is value for money.
Edit (addition): I noticed that the percent left dropped about 1% per week when not used. My problem was that I didn't realise I had to hold the button down for a few seconds to turn it off. Now it does not lose when not used.

Awesome battery bank for the size.
A small brick but very handy to charge a laptop and other devices at the same time.

I use to import and sell li-ion cells and I would struggle to put together one of these at these specs for the price. I could have a far higher spec'd one manufactured but the retail cost would be substantially more.
These are great bang for buck.

The soft felty bag is a bit of a dirt magnet when you carry it outdoors. But that's not the device itself. Awesome battery bank for the size.

UPDATE: After being stopped at Airport security, I was told it was not legal to take on the plane because the maximum output was 250W . They did not know the difference between Watts and WattHour. The Wh value of 99.54 is calculated using the nominal cell voltage of 3.6 volts x 27,650 mAh Make sure you have the correct information available on how this Powerbank is rated at 99.54 Wh.

After a bit of research and reading reviews, decided on this power bank. As mentioned elsewhere, it's quite hefty but will replace the two 'ordinary' powerbanks I take on holiday.

After a bit of research and reading reviews, decided on this power bank. As mentioned elsewhere, it's quite hefty but will replace the two 'ordinary' powerbanks I take on holiday. I also purchased the charging base and was a little worried when the powerbank didn't turn on or show any signs of life when I put it onto the base. It turns out that if the powerbank is completely flat, you need to use the USB C cable to get a few percent of charge into the power bank. Once that was sorted, I was able to get it fully charged fairly quickly on the 100W base. While that was going on, I tried pairing it with bluetooth, only to find out I needed. to install the app first. From thereon in, it was all go. The app communicates using bluetooth and provides a quick and easy readout of what is happening - the charging rate, how long until it is charged, and when it is used to charge devices, there is a readout of the power and voltage from each of the connected ports.

The first thing I tried was an iPhone 16. No problems. Next was a Macbook Air M4, which was charged much quicker than using a 70W charger.
I have no regrets buying this 27650 mAh Powerbank and 100W Base charger. It's a little pricey but well worth the investment in two high quality products. If you can afford it, I recommend this as a Powerbank for phones and modern laptops. If "She who must be obeyed" allows, I might even buy another one for her.

I first plugged this in and saw that is was going to take 20 hours to charge, so I plugged it into a macbook charger - and still 20 hours, so I tried a ipad air charger and viola! down to 70 minutes.

I guess Anker want you to buy the charging base that the terminals on the bottom are for.

Now that I have the right charger, it's a great device.

The tasty looking display shows you % charged and how much juice is being drawn in watts.

Definitely not a cheap power bank, but it does have a good capacity and it is very fast.
The speed you can charge the devices would depend on the devices themselves, but to me the most useful thing is to be able to recharge the powerbank quickly.
I tested out charging from my very fast USB charger, the Anker Prime power bank reported 140w charging speed. I charged up a couple of devices and got the power bank down to 38%, then I plugged in the charger and saw the reported 140W charging, I checked on it after 25 minutes and the power bank was at 100% charge already. 38% - 100% in less than 25 minutes sure beats the first powerbank that I bough...view more Definitely not a cheap power bank, but it does have a good capacity and it is very fast.

Would I recommend this power bank? Well, only to people that don't mind paying a lot of money to have a top quality device. If the price doesn't put you off then this is a great power bank that can be recharged super fast.

Charging your laptop and your phone was a game changer to me ! Excellent to use on a business trip. Charging your laptop and your phone was a game changer to me ! Excellent to use on a business trip.

Overall, this power bank exceeds my expectations and I highly recommend it to anyone in need of a reliable, high-capacity mobile charger.

Amazing power and very quick charging can even use the two type c port to charge the power bank even faster. Amazing power and very quick charging can even use the two type c port to charge the power bank even faster.
