Most “baseus power bank” searches end at phone-charger sizes, but this one is aimed one tier up: the Baseus 145W Laptop Power Bank packs a 20,800mAh cell (about 77Wh) behind a 145W USB-C output — enough wattage to actually charge a MacBook, a Dell XPS, or a Steam Deck at meaningful speed, not the trickle that 30W banks deliver. The honest math and the honest limits are both below.

Price is as of writing: $69.99, no coupon.

The MacBook Math (Honest Version)

“Charges a MacBook” needs numbers, not marketing:

• MacBook Air (13″, ~52.6Wh): roughly 1.2–1.3 full charges — a real workday extension
• MacBook Pro 14″ (~72.4Wh): roughly one full charge — but at 145W vs the Pro’s 96–140W charger, expect close-to-full-speed charging with slightly longer top-off time on the highest-draw models
• MacBook Pro 16″ (~100Wh): the bank holds less energy than the laptop — expect a 60–70% top-up, not a full charge
• Phones: ~4–5 iPhone charges; the remaining USB-A/C ports run phone and earbuds while the USB-C handles the laptop

Translation: this is a one-workday insurance policy for a laptop, not a multi-day off-grid solution. That’s what 77Wh in a flight-legal body buys, and no bank at this capacity promises more.

Daily-Carry Reality

The digital display is the feature you’ll use most: exact percentage remaining, so “do I have enough to finish this call” becomes a glance instead of a guess. The ~77Wh rating keeps it under the FAA/airline 100Wh carry-on ceiling — the listing markets it as flight-approved, but always confirm the current policy of your specific airline, as rules and enforcement vary.

Honest trade-offs: this is a heavy bank — the 20,800mAh-plus class weighs north of a pound, and you’ll feel it in a laptop bag. Recharging the bank itself from empty takes real time on a standard charger; pair it with a high-watt wall charger to minimize that. And 145W is the peak single-port figure — split across all four ports simultaneously, per-port output drops.

Who Should Buy It

• MacBook Air / 14″ Pro owners who work from cafés, trains, or airports — the core audience
• Steam Deck / handheld gamers — 145W covers handheld gaming draws comfortably
• One-bag travelers — laptop + two phones + earbuds from a single carry-on-legal brick
• Not for: phone-only users (a 10,000mAh bank at half the price and weight is the honest pick — see our Baseus power bank lineup guide)

Final Verdict

The baseus 145w power bank does one job — laptop-class charging in a flight-legal body — and does it with the two features that actually matter at this tier: enough wattage to be meaningful, and a digital display that removes battery anxiety. The weight is the tax, the 16″ MacBook caveat is the limit, and both are stated plainly. At $69.99 as of writing, it’s a fair price for workday independence from wall sockets.

FAQ

Q: Can this power bank charge a MacBook Pro?
A: Yes — 145W USB-C PD covers MacBook Air and 14″ Pro at close to full charger speed, and tops up a 16″ Pro (100Wh battery) by roughly 60–70% per cycle. The bank’s ~77Wh capacity is the physical limit, not the wattage.

Q: Is it allowed on planes?
A: At ~77Wh it sits under the standard 100Wh carry-on limit that FAA and most airlines use, and the listing markets it as flight-approved. Power banks must go in carry-on, never checked baggage — and confirm your specific airline’s current policy before flying, as rules vary.

Q: How many phones can it charge?
A: Roughly 4–5 full iPhone charges from one cycle, or laptop plus a couple of phone top-ups simultaneously across the four ports — with the caveat that total output is shared when multiple ports run at once.

Q: Does it come with cables?
A: Check the listing box contents for your region before ordering — the core spec is the 4-port output and 145W rating. Budget for a good 100W+ USB-C cable if you don’t own one; it’s required to actually reach laptop-class speeds.
