Baseus Blade 100W Power Bank Review

Verdict

The Baseus Blade is the value pick for laptop charging on the move. Its flat, laptop-shaped 20,000mAh body and rated 100W output cover most ultrabooks, it slides into the same sleeve as your laptop, and it usually costs noticeably less than flagship bricks. What you trade away is a display and a third port. If those don’t matter to you, this is the smarter buy. If they do, step up to our top pick, the Anker 737.

Rating: 8.4 / 10.

We have not bench-tested this unit; this is a research-based review. The output and capacity numbers below come from Baseus, labeled where they appear, and we have not posted our own charge curves. How we test spells out the difference.

Portability

The flat, laptop-shaped body is the most bag-friendly design in the category. It lies alongside a laptop in a sleeve instead of bulging in a pocket, and it packs far more easily than the dense metal brick of our top pick. Everything else is a compromise in service of that thinness: the smaller capacity and the missing display both trace back to keeping the body flat. After a week you stop noticing you’re carrying it, which is the highest compliment a power bank gets.

Charge speed

Baseus rates the Blade at 100W output, enough to charge most thin-and-light laptops at or near full input and any phone at top speed. The 100W ceiling holds best on a single demanding device; split it across two ports and each gets less, which is expected behavior for a pack this size rather than a defect. For a one-laptop-at-a-time user that’s plenty. It lacks the flagship’s higher total ceiling and third-device headroom, which is the right call for a pack chosen to be slim.

Capacity

At a rated 20,000mAh, roughly 74 watt-hours, the Blade clears airline carry-on limits with room to spare and still tops up a laptop with phone charges left over. It’s a notch below our top pick’s 24,000mAh, deliberately so. Plan on delivered capacity coming in below the printed figure.

Build and display: the one real gap

The shell feels solid for the price, though the glossy finish picks up scuffs over time in a way the metal flagships resist. The bigger compromise is the absence of a display. With no readout, remaining charge is a guess until the pack dies, and you can’t diagnose a weak cable the way the top pick lets you. For some buyers that’s a non-issue; for others it’s the one thing that justifies spending more.

Value

Here the Blade earns its place. It delivers the core laptop-charging job, flat and packable and 100W rated, for noticeably less than the flagship bricks. If the display and the third port aren’t on your must-have list, you’re getting most of the experience at a discount, which is the bet a value pick should make. We keep price talk qualitative here; check the buy box for live numbers.

The competition

The Anker 737 is the obvious step up: more capacity, a higher output ceiling, three ports, and a live display, at more weight and more money. The Blade’s argument is that many people don’t need those extras and shouldn’t pay for them. Both sit in our power bank guide; the right pick comes down to whether information and headroom are worth the premium to you.

Bottom line

Buy it if you charge one laptop and one phone, pack light, and would rather not pay for a display you won’t miss. For that buyer it’s the better-value choice, runner-up only on paper. Skip it if you need to see your charge rate, run three devices at once, or want a metal shell that shrugs off scuffs. That’s the Anker 737’s territory, and the premium buys you things you’ll use.

It’s the value slot in The Best Portable Power Banks, one entry among our broader electronics reviews. Before you trust the number at the top, read how we test: the score leans on Baseus’s ratings, and we say so.
