Purpose and User

The Ugreen PB536 Nexode is a 20000mAh power bank designed for travellers and commuters who need to keep a phone, tablet and accessories charged without carrying separate cables. Its integrated USB-C braided cable handles both input and output, reducing clutter in a bag. The 45W maximum output suits smartphones and tablets rather than high-power laptops.

Sustained Load Behaviour

The 20000mAh lithium-ion cell delivers multiple full charges, approximately 3.7 times for an iPhone 16 Pro or two times for an iPad Pro, before the bank itself needs recharging. When three devices draw power simultaneously through the built-in cable, USB-C port and USB-A port, the 45W total budget is shared across all outputs. Auto-grade battery management and multiple protection circuits maintain stable voltage during extended sessions.

Deciding Specification

The single figure that determines suitability is the 45W maximum output, which covers fast charging for current iPhone and Samsung flagships but will not drive larger laptops at their peak rates. Buyers who need 65W or higher for a notebook should look at the 100W, 130W or 145W models in the same range.

Questions about this item

How much heat or power draw should I expect from the 45W output when the bank runs all day?

The unit delivers up to 45W through its built-in USB-C cable or ports; with a 20000mAh lithium-ion cell at 7.4V it will warm slightly under sustained load but has no active cooling.

What cables or chargers must I already own to recharge the bank itself at 45W?

You need a USB-C charger capable of 45W input and a USB-C-to-C cable unless you use the integrated braided cable, which handles both input and output.

Will the USB-A port and 45W USB-C outputs charge my older iPhone and iPad models at the same time?

Yes, the bank provides three simultaneous outputs — built-in USB-C cable, USB-C port and USB-A port — so legacy Lightning devices via USB-A and newer USB-C devices can charge together.
