Rank #7 in Best 20000mAh Power Bank: 10 Ranked by Real Charge Counts
UGREEN Nexode 20W 20,000mAh Power Bank
Price and rating as shown on Amazon when we collected them. Both change.
The UGREEN Nexode is the number 7 entry in this guide: a 20,000mAh power bank at £21.99, rated 4.5 out of 5 from 4,251 ratings. It lists three ports (2x USB-A, 1x USB-C), a 6-hour charge time in the spec field, and a claim of 4.5 full charges for an iPhone 15 Pro and 3 for a Galaxy S24 Ultra — squarely inside the 3.4-to-7 spread this guide keeps running into. The same bullet that gives those charge counts also promises "5-7 days of battery life", a unit that does not match the 4.5 full phone charges offered in the same breath.
Two numbers in this listing do not line up. The first bullet advertises "QC 22.5W and PD 20W", while the spec field for Output Wattage says 20 Watts and the product name says PD 20W; nothing in the listing says which port, or which device, reaches 22.5W. The name also calls it a "Built-in Cable" model, yet the bullets describe only 2 USB-A ports and 1 USB-C port and the spec's Connector Type is USB Type A and USB Type C. Everything on this page comes from the Amazon listing — its bullets, its spec fields and its customer reviews — and not from any test of our own.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“Arrived yesterday so here are my first impressions. Larger and heavier than I expected - replacing a 13000 mAh power bank which is quite small and lightweight. Took all day to charge from c.26% to 100% using a standard Apple charger plug (A1399 which is 5W) - reading through the product details it recommends a 20W charger as a minimum so I ordered a pair of 60W chargers... Once fully charged, used it to charge an iPhone 14 Pro from 20% to 100% which it did relatively quickly - the power bank reduced from 100% to 80%. Have now had it on charge using the new 60W charger and it has got back up to 100% quite quickly. I like the % display of battery level - a big improvement on the 4 lights on my old power bank... Very happy with the purchase for the price paid.”
Verified purchase“Good quality power bank with a clear % contents gauge display. Only issue I didn't pay much attention to is the size & weight, as this is slightly thicker and heavier than my existing belkin of the same capacity. But the belkin is down to only one usable out port hence the purchase. Other than that, it seems to be a good purchase. Maybe need to take a bag rather than keeping it in a jacket or trouser pocket!”
