Rank #9 in Best Power Bank 2026: 10 Ranked on Real Delivered Capacity
Power Bank 27000mAh with 4 Built-in Cables, 22.5W
Price and rating as shown on Amazon when we collected them. Both change.
This is the unbranded high-capacity option, and like the Charmast it leads with built-in cables: four of them, alongside a 27000mAh battery and fast charging. The combination of a large cell and no cable to remember is the pitch.
The listing does not carry a brand name, which means the evidence has to do the work instead. It carried 5,795 ratings at 4.5 stars at the time of collection, a small but solid sample. As always, the rated capacity is measured at the cell rather than at the port. Everything here comes from the Amazon listing rather than our own testing.
How those 5,795 ratings break down
An average hides its own shape. This is the spread behind the 4.5 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Very good product and good price (bought on offer) for the quality and performance. Easy to charge and use - would recommend.Does take a few hours to fully charge but from a single full charge this power bank offers 3 or 4 full charges for devices - charging speed is reasonably fast with option to plug in your own fast charging wire.Good option of charging points (have only used usb-c and iPhone so far). Compact design making it easy to carry with a little carry handle - can be a little awkward hold if you don’t want to rest your device on top but that is more about preference than design or performance.”
Verified purchase“This power bank is so handy, especially when I’m out and about. I love that it has different connectors built in, so I can easily charge my phone or Kindle without having to carry around lots of different cables. The charge lasts for ages and I really like that it shows the percentage remaining, so you always know how much power you have left.My daughter is always robbing it off me, so I’ll probably have to get another one for her! The fast charging is a real bonus too, and it’s great to have something so convenient and reliable when you’re out for the day. Definitely one of those gadgets I didn’t realise how much I needed until I had one!”
