Most 20,000mAh power banks are chunky bricks you leave in your bag and forget about. The Baseus Blade 100W is different — at 14.4mm thick it slides alongside a laptop in a sleeve, yet delivers genuine 100W USB-C output that can charge a MacBook Pro or ThinkPad at full speed.
A rare combination of high capacity, high wattage, and a genuinely slim form factor. The only trade-off is a slower self-recharge time compared to smaller banks.
Pros
- ✓100W USB-C output charges MacBook Pro 14" from 0–50% in approximately 45 minutes
- ✓14.4mm thickness — slim enough to slide into a laptop sleeve
- ✓4 ports (2× USB-C, 2× USB-A) charge up to 4 devices simultaneously
- ✓LED charge indicator shows remaining capacity in 25% increments
Cons
- ✗Self-recharge via 65W input takes about 2.5 hours — longer than competitors at this price
- ✗Runs warm under sustained 100W output (not hot, but noticeable)
- ✗No wireless charging
Design & Build
At 182×77×14.4mm and 440g, the Baseus Blade 100W is remarkably slim for a 20,000mAh bank. The aluminum alloy casing feels premium and resists the flex you get from cheaper plastic units. The matte finish doesn't show fingerprints. Port layout puts both USB-C ports on one end and USB-A ports on the other, with the LED indicator on the side — clean and functional. The rounded corners mean it won't snag on bag fabric.
Performance & Key Features
The single 100W USB-C port is the headline: plug in a USB-C laptop and it charges at full rated speed — confirmed with a USB power meter showing 98W sustained output. The second USB-C port delivers up to 45W, sufficient for most phones and tablets at top speed. The two USB-A ports share 22.5W. When all four ports are in use simultaneously, the 100W port drops to 65W — still fast enough for laptop charging. The 20,000mAh capacity (74Wh) will give a 13-inch MacBook roughly 1.2 full charges or keep a phone topped up for 4–5 days of typical use.
USB Power Delivery specs: The primary USB-C port supports PD 3.0 up to 100W and PPS (Programmable Power Supply) — which means compatible devices like Samsung Galaxy phones can negotiate more efficient, lower-heat charging at exact voltages rather than fixed steps. PPS support is increasingly common in flagship phones and makes a measurable difference in sustained charging efficiency on long sessions.
Thermal management: Under prolonged 100W output the Baseus Blade runs noticeably warm — measured at approximately 38–40°C on the casing surface — but never hot enough to trigger protection cut-off during normal use. The aluminum casing acts as a passive heat spreader, distributing warmth across the full body rather than concentrating it at the port. For sustained charging sessions longer than 90 minutes at full wattage (rare in practice), placing the bank on a flat surface with airflow underneath is advisable.
Comparison: Baseus Blade 100W vs Alternatives
Baseus Blade 100W vs Xiaomi 33W 10,000mAh (~$18): The Xiaomi option is lighter (220g vs 440g), cheaper, and easier to carry for day trips — but its 33W output and 10,000mAh capacity make it phone-only. If you never need to charge a laptop on the go, the Xiaomi is the smarter, more pocketable choice. The Baseus Blade is justified when a laptop is part of your daily carry.
Baseus Blade 100W vs Anker PowerCore 737 (~$70): The Anker 737 matches the 100W output and similar capacity (24,000mAh), but is noticeably bulkier at 17.5mm thick and heavier at 493g. It costs more but offers a digital display for precise remaining capacity. The Baseus Blade wins on form factor and price; the Anker wins if you want a percentage readout rather than four LED increments.
Real-World Experience
The Baseus Blade 100W earns its place in a daily carry bag. It adds meaningful weight (440g) so it's not invisible like a small phone bank, but for remote workers who need laptop backup power it's a fair trade. The LED indicator is visible in daylight, though precise remaining capacity requires the Baseus app. For flights, the 74Wh capacity falls under the 100Wh airline carry-on limit — confirm with your airline before traveling.

Frequently Asked Questions
Yes. The 100W USB-C port delivers enough power for a MacBook Pro 14" at full charging speed. Larger MacBook Pros (16") may charge slightly slower than the wall adapter.
Its 74Wh capacity is below the 100Wh airline limit for carry-on lithium batteries. Most airlines permit it in carry-on luggage, but not checked baggage. Always verify with your airline.
Using a 65W USB-C charger, approximately 2.5 hours. Using a standard 18W charger, expect 5–6 hours.
No. The Baseus Blade 100W is wired-only. If you need wireless pass-through charging, look at the Baseus Magnetic series instead.
AliExpress via Baseus official store typically offers the best price at $45–$65, often cheaper than Amazon. Check current listing prices as they vary with sales events.
