UGREEN Nexode 100W Power Bank Review: 20,000mAh Laptop Charger

Out of the box, the Nexode 100W reads as a serious laptop bank, not a pocket topper. It’s a dense, square-edged block at 420g, closer to a small hardback than a phone charger.

The matte shell picks up scuffs more readily than the brushed finishes on some rivals, something Trusted Reviews also flagged.

A simple LED readout on the front shows a rough charge level, four dots rather than the precise percentage screen UGREEN reserves for its pricier Nexode models.

What lifts the first impression is the kit in the box. UGREEN bundles a braided 240W USB-C cable rated well beyond anything this bank will draw, plus a soft travel pouch and a manual. There’s no cable built into the body, so that included lead is the one you’ll carry.

The Nexode 100W measures 139 x 80 x 26.5mm and weighs 420g, putting it mid-pack for the 20,000mAh laptop class. UGREEN publishes both figures on its 25188 product page, and the weight there is the product weight rather than a shipping weight.

Inside are 21700 lithium-ion cells, the larger high-density format you want for sustained high-wattage output. UGREEN specifies this on the product page; we have not opened a unit to confirm it.

The port layout is two USB-C and one USB-A along the top edge: USB-C1 is the 100W input and output port, USB-C2 tops out at 30W, and the USB-A handles up to 22.5W. That is the layout that makes the 100W claim possible, and it is also why the USB-A port is best thought of as the phone or earbuds socket rather than a third serious output.

On safety, UGREEN specifies UL94 V-0 flame-retardant housing and a full protection suite covering over-voltage, over-current, over-charge, over-discharge, high temperature and short circuits. Confirm the exact certification marks on the unit and packaging when yours arrives.

In the box

You get the power bank, a 240W USB-C to USB-C cable, a travel pouch and a user manual, on UGREEN’s own list. If you want a sense of what a good 240W cable does for a pack like this, our UGREEN 240W USB-C cable review covers the one in the pouch.

That is genuine laptop-grade output, not the 30W to 45W trickle that many 20,000mAh banks quietly cap at.

MacRumors ran the everyday laptop and phone tests. An iPhone 15 Pro reached about 60% in 30 minutes and full in under an hour, and the remaining capacity could refill that iPhone from near empty more than twice. So the practical picture is one full laptop charge with a little headroom, or two-plus phone refills.

UGREEN does not publish a surface temperature and no independent outlet recorded one, so we are not quoting heat figures we cannot stand behind.

Multi-device behaviour is the main caveat. The moment a second device is connected, the main port eases from 100W to around 60W, with the secondary USB-C and USB-A then sharing roughly 20W between them.

In Trusted Reviews’ all-three-port test, the USB-A delivered about 7W and the second USB-C a little over 14W. It’s a one-fast-device bank that can keep a phone and earbuds topped up on the side, not a true three-device hub.

Darleene’s version: Charge one thing fast, or a few things slowly. Plug the laptop in on its own and it flies; add a phone and earbuds and the power shares out.

The Nexode 100W supports pass-through, meaning it can charge a connected device while the bank itself is being recharged from the wall.

MacRumors confirmed this in use, which makes it handy as an overnight desk hub: leave it plugged in, charge your phone or laptop off it, and the bank tops itself back up in the background.

Because the input is capped at 65W, expect the bank’s own refill to slow while it is also feeding a device, so for the fastest top-up, recharge it on its own.

At 420g and 26.5mm thick, this is a laptop-bag or jacket-pocket power bank, not a jeans-pocket one.

That weight is the trade-off for genuine 100W output and a 20,000mAh cell, and it is in line with rivals in the class rather than unusually heavy.

The included pouch keeps the scuff-prone shell and the 240W cable together in a bag, which is more useful than it sounds on a travel day.

For air travel, the 72Wh rating is the number that matters, and it sits well inside the limits.

At 72Wh, the Nexode 100W is under the 100Wh threshold airlines apply to lithium batteries, so it travels in carry-on hand luggage on the major carriers.

It must go in the cabin, never checked baggage. Always confirm with your airline before you fly.

Our guide to taking a power bank on a plane covers the cabin rules in detail, and you can check any capacity in seconds with our mAh to Wh calculator.

UGREEN specifies UL94 V-0 flame-retardant materials and high-quality 21700 cells, with a protection suite spanning over-voltage, over-current, over-charge, over-discharge, high-temperature and short-circuit protection. Confirm the exact certification marks on the unit and packaging when yours arrives.

The UGREEN Nexode 100W does the hard thing well. It charges a laptop at close to full speed from a 20,000mAh cell that still clears airline carry-on rules, and it backs that up with measured efficiency most rivals cannot match.

You pay for it in bulk and in the lack of a built-in cable, and you give up real speed if you try to charge several devices at once.

For one person who wants a single bank to keep a laptop and a phone going through a travel day, it is an easy recommendation.

The UGREEN Nexode 100W is a focused bank that knows what it is for. It will not win on size or pocketability, but it delivers the genuine laptop-grade charging and airline-friendly capacity that most 20,000mAh banks only hint at, and the measured test data backs that up.

If you want one bank to carry a laptop and a phone through long days and longer journeys, it belongs on your shortlist. See how we test, or see where it ranks against the rest in our best 20000mAh power banks roundup.
