The UGREEN Nexode 45W 20000mAh Power Bank is the third pick in this guide. It is a 20,000mAh pack with a USB-C cable built into the body, three ways to charge at once (the built-in cable, a USB-C port and a USB-A port) and an LED screen showing what is left in the tank. It is listed at £23.98 with 4.4 stars from 4,379 ratings.

On the question this guide keeps coming back to — what a 20,000mAh claim actually delivers — UGREEN puts itself mid-table: 3 full charges for a Galaxy S25 Ultra, or 4.2 for an iPhone 16. That sits below the 7 iPhone 17 charges Riapow claims and above the 3.4 iPhone 16 charges Baseus claims. Its weight field says 468 g, which is heavier than the 425 g that is the highest battery weight quoted anywhere else in this guide — and the same listing also lists "lightweight" among its special features. Everything on this page comes from the Amazon listing, not from testing by us.

## Questions people ask

**How many times can the UGREEN Nexode 45W charge a phone?**

The listing claims 3 full charges for a Galaxy S25 Ultra or 4.2 charges for an iPhone 16.

**How heavy is the UGREEN Nexode PB536?**

The item weight field says 468 g, while the special features field in the same listing lists "lightweight". Both figures sit in the same Amazon entry.

**How fast does it charge?**

UGREEN claims 45W output, enough to take a Galaxy S25 Ultra to 61% in 30 minutes with Super Fast Charging 2.0, and the same 45W on input to refill the pack.

**Can the UGREEN Nexode charge three devices at once?**

Yes. The listing describes a built-in USB-C cable, a USB-C port and a USB-A port, with an LED screen showing the remaining battery level.

**Do I need to bring a cable?**

The USB-C cable is built into the NGREEN unit and doubles as a lanyard for a bag, so it handles both charging out and recharging in.

**What do the voltage and amperage figures mean?**

The spec block lists 7.4 volts and 3 amps alongside a 45W maximum output claim. The listing does not explain how those two sets of numbers relate to each other.
