Detailed overview: Baseus Blade 100W Power Bank
The Baseus Blade is a power bank designed to travel alongside a laptop without giving up compactness. Its 20000mAh capacity (74Wh) and 100W output make it a serious companion for charging a laptop, a tablet or a smartphone, all inside a remarkably flat housing.
It has four ports in total: two USB-C (up to 100W each, shared across the total power budget) and two fast USB-A ports, so up to four devices can charge at the same time. Power Delivery 3.0, Quick Charge 4.0, SCP and FCP cover nearly every recent USB-C smartphone, tablet and laptop. It can charge a MacBook Pro to 50% in around 30 minutes, and recharges itself fully in 1.5 hours through its own 65W USB-C input.
The built-in display is a genuine day to day advantage: it shows the remaining battery percentage, the current charging wattage and the estimated time left, all at a glance, a feature still uncommon at this level of compactness.
The Baseus Blade's real strength stays its format: just 17.8mm thick for 506g, it is thinner than most laptops and slides easily into a laptop bag or backpack without adding bulk. A 100W USB-C to USB-C cable and a carrying pouch are included in the box.
Its limits are those of its category: no wireless charging, and the wall charger needed to recharge it at full speed (65W) is not included, so an existing 65W charger has to be used. Some users also report faster than average wear on one of the ports over time, or reduced capacity after several months of heavy use, worth watching despite the 24 month warranty.
Baseus has now discontinued the Blade 100W 20000mAh in Europe, replaced in its lineup by newer laptop power banks such as the Blade HD and the EnerFill FC41. No UK retailer currently lists it in stock, so the price shown here is converted from the EUR reference price at the current exchange rate rather than a live UK offer. For anyone who tracks down a remaining EU listing, it stays one of the thinnest 100W power banks built for nomadic laptop use.

Comparison
How does the Baseus Blade compare with other 100W and above power banks for laptops?
| Criterion | Baseus Blade | UGREEN Nexode 100W | Anker Prime 20000 (200W) |
|---|---|---|---|
| Capacity | 20000mAh / 74Wh | 20000mAh / 72Wh | 20000mAh / 72Wh |
| Max power | 100W | 100W | 200W |

| Display | Yes (%, W, time) | Yes | Yes |
| Price | £78.00 | £42.85 | £98.57 |
At equal capacity, the Baseus Blade stands out for its extra-slim format (17.8mm) and its four ports, handy for charging several devices without an adapter. The UGREEN Nexode 100W costs less but is noticeably thicker and limited to a single USB-A port. The Anker Prime climbs to 200W for the most demanding needs, at the cost of a much thicker body and a higher price. To fit a large 100W capacity into a thin sleeve, the Baseus Blade remains the most practical choice on paper, though it is worth checking current availability first since Baseus has discontinued the model.

Our tester's review: Guillaume Hoarau
We carried the Baseus Blade on business trips for several weeks, and its wafer-thin body still surprises every time it comes out of the bag: barely thicker than a wall charger, it takes up almost no room in a laptop sleeve. The 100W output delivers on its promise, a laptop regains a good half of its battery in half an hour, while a phone charges on another port without slowing the laptop down. The display is genuinely useful, no more guessing how much is left, everything shows up in percentage and watts. The two USB-A ports come in handy for earbuds or a headlamp at the same time. The catches: no wall charger is included, and some users report reduced capacity after months of heavy use, something we could not verify over the long term ourselves. Baseus has since discontinued the Blade in favour of newer models like the Blade HD and EnerFill FC41, and stock has dried up across UK retailers, so this remains a solid pick only if you can still track one down.
