Home/Universal/Power Banks/Anker 737 Power Bank (140W 24K)
The Anker 737 is a portable laptop charger, not a phone battery. 140W over USB-C fast-charges a MacBook Pro, 24,000mAh covers a full laptop charge plus phone top-ups, and a smart display shows exactly where you stand. It weighs around 630g — a deliberate carry.

Version reviewed: Anker 737 Power Bank (PowerCore 24K), 140W 24,000mAh 3-port with smart display · ASIN B09VPHVT2Z · Amazon US listing · Anker model A1289.
One-sentence verdict: Buy it if you genuinely need to charge a laptop away from an outlet and will carry a heavy bank to do it — skip it if you only charge a phone, want something light, or expect a $110 bank to last a decade.
140W and 24,000mAh — a genuine laptop bank, and it weighs like one.

A dense black brick with a small screen, two USB-C ports and a USB-A port. It feels serious — the weight is all battery and GaN electronics. The display is small but readable and shows real numbers. Build quality is good; the main concern is a pattern of owner reports of the bank degrading or failing after somewhat over a year, which is short for a $110 device even if it is a minority.
Plug a laptop or phone into a USB-C port. The screen shows the wattage and an estimated time. Recharge through USB-C with a capable adapter for the fast ~70%-in-30-minutes refill.
For a power bank, performance is usable capacity, charge speed, heat, recharge time and multi-device behaviour. Capacity is a full laptop charge plus extras. Charge speed at 140W is the headline — it genuinely fast-charges a MacBook Pro. Heat is actively monitored and shown. Recharge time is fast for the capacity. Running three devices splits the total budget across them.
Works with:
Not compatible:
Most units perform for years. A recurring minority report degradation or failure after roughly 16 months, which is the main durability caveat and is more painful at this price. Anker’s 24-month warranty covers that window, and Anker support is generally responsive.
At $109.99 on Amazon (checked August 26, 2026), it is priced as a premium laptop bank, which is what it is. Compared with buying a lesser bank plus a wall charger, it is not unreasonable for the capability.
The value case rests entirely on whether you need 140W laptop charging away from an outlet. If you do, few banks do it as cleanly. If you do not, you are paying triple for capability you will not use, and the reports of failure after ~16 months sting more at this price. We would call it a fair buy under about $90.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| Anker 737 Power Bank (140W 24K) (this bank) | Fast-charging a laptop away from an outlet | 140W, 24,000mAh, smart display, 24-month warranty | Heavy, ~$110, some failures after ~16 months | $109.99 |
| UGREEN Nexode 20,000mAh 45W | Most people who touch a laptop occasionally | Keeps a MacBook Air alive; built-in cable; half the price | 45W not 140W; will not fast-charge a MacBook Pro | $45.99 |
| Anker 10,000mAh 30W Power Bank | Phone-only everyday carry | Pocketable, built-in cable, ~$30 | No laptop charging | $29.99 |
Unless you need to fast-charge a power-hungry laptop, the UGREEN Nexode 20K covers laptop-alive duty for half the price and weight. For phone-only carry, the Anker 10K is the pick. Prices are Amazon figures from August 26, 2026.
The Anker 737 is a genuine portable laptop charger. 140W over USB-C fast-charges a MacBook Pro rather than just trickling it, 24,000mAh covers a full laptop charge plus phone top-ups, and the smart display tells you exactly where you stand on a long trip. It refills itself fast and carries a 24-month warranty. Its 4.4-star average across more than 17,000 buyers reflects a capable bank.
The costs are weight, price and a durability question mark. It is around 630 g, it is $110, and a recurring minority of owners report it degrading after somewhat over a year — short for the money. If you truly need 140W laptop charging on the move, it earns its place. If you do not, a 45W bank does laptop-alive duty for half the price and half the weight.
