Price and rating as shown on Amazon when we collected them. Both change.
Number 8 in this guide is the Baseus Qpow3, a 20,000mAh pack with two USB-C cables built into the body, a claimed 45W PD3.0/PPS output, and a price of £29.98. It carries a 4.5 rating from 1,210 ratings. It is also one of the heaviest packs in the list: the listing gives 361 g for both Item Weight and Battery Weight, which is roughly what a genuine 20,000mAh cell weighs — put that beside the 40 g battery weight quoted elsewhere in this guide and you can see which listing is doing the work.
What makes this entry interesting is the direction its numbers run. Most 20,000mAh listings here claim six or seven full phone charges; Baseus claims 3.4 for an iPhone 16, the lowest figure in the guide. And while the copy calls the pack a "2000mAh Powerbank" in several bullets and in the what's-in-the-box line, the Battery Capacity field says 20,000 and the 361 g weight sits with the larger number, not the smaller one. Everything on this page comes from the Amazon listing for this model, not from testing by us.

Questions people ask
How many times will the Baseus Qpow3 charge my phone?
The listing says the 20,000mAh Baseus Qpow3 charges an iPhone 16 about 3.4 times, an iPad Pro 1.9 times and a Mate 60 about 2.4 times.
How heavy is the Baseus 45W power bank?
The listing gives 361 g for both Item Weight and Battery Weight; buyers describe it as a little heavy or a wee bit weighty.
Does the copy really call it a 2,000mAh power bank?
Yes. Several bullets and the what's-in-the-box line call it a "2000mAh Powerbank", while the Battery Capacity field says 20,000.
How long is the warranty?
The bullet promises a 24 month warranty, while the Warranty Type spec field says "Lifetime" — the two figures do not agree.
How many devices can it charge at once?
The listing says four ports: two built-in USB-C cables plus a USB-C port and a USB-A port, and claims you can charge up to four devices at a time.
What does the spec block say about voltage?
It lists 5 Volts, while the headline claims 45W PD3.0/PPS — 45W at 5V would need 9A, and the listing never reconciles the two.
