Is the Anker 737 Power Bank Still Worth Buying?
For most people, yes, if you can find it discounted. It packs 24,000mAh and 140W of output into one bank, enough to charge a phone five times over or top up a PD 3.1 laptop. It is heavier than newer Anker banks and lacks a built-in cable, so check the price against the Anker Prime 200W and the Anker Laptop Power Bank (A1695) before you buy.
The one-line verdict
The Anker 737 is a 24,000mAh, 140W power bank that can top up a phone five times or put a real dent into charging a laptop. It is a solid choice for most people who need serious portable power, but it is a few years old now, so it is worth cross-shopping against Anker’s newer banks before you buy at full price.
Who this is for
- Frequent travelers who want one bank that covers a phone, tablet, and laptop
- Remote workers who need backup power for a laptop during outages or travel days
- Anyone charging multiple devices at once and tired of power banks that throttle when you do
Skip it if you only ever top up a phone once a day. A $25 to $30 power bank does that job without the extra weight and cost.
What 24,000mAh actually gets you
Based on Anker’s published specs and third-party testing from outlets like TechRadar and StorageReview, the 737 provides roughly:
- iPhone 15/16-class phone: around 5 full charges
- iPad Air: around 2 full charges
- MacBook Pro 14-inch: roughly 1 full charge, depending on the laptop’s own battery size
- AirPods case: 20-plus charges
These are estimates based on the battery’s rated capacity, not a lab measurement we ran ourselves, so treat them as a useful ballpark rather than an exact promise.
Design and output
The 737 has two USB-C ports and one USB-A port, and Anker rates the USB-C ports for up to 140W combined, enough to fast-charge devices that support USB-C Power Delivery 3.1, including recent 14-inch and 16-inch MacBook Pro models. To actually hit 140W you need both a PD 3.1-capable cable and a PD 3.1-capable device; a generic USB-C cable will still charge, just more slowly.
The onboard display shows an exact percentage rather than the usual four-LED guess, which is a small but genuinely useful upgrade over cheaper banks.
At 86.4Wh, it sits just under the FAA’s 100Wh carry-on limit, so it is fine to bring on a flight in carry-on luggage.
The trade-offs
- Weight. At about 1.4 lbs (630g), this is not a bank you forget is in your bag. If pocketability matters more than capacity, look elsewhere.
- No built-in cable. Anker’s newer Laptop Power Bank (A1695) ships with an integrated USB-C cable; the 737 does not, so you are carrying a separate cable.
- It is not the newest option. The 737 has been on the market since 2022. Anker has since released the Anker Prime 200W Power Bank, reviewed separately on grimtech, and the Anker Laptop Power Bank (A1695), which trades some peak wattage for a lighter build and a built-in cable.
How it compares
| Anker 737 | Anker Laptop Power Bank (A1695) | Anker Prime 200W | |
|---|---|---|---|
| Capacity | 24,000mAh | 25,000mAh | ~20,000 to 27,650mAh (model-dependent) |
| Max output | 140W (USB-C) | 165W total, 100W per port | Up to 200W+ |
| Built-in cable | No | Yes | Varies by model |
| Best for | Buyers who find it discounted | Travelers who want less bulk | Buyers who want the newest, highest-output option |
See our Anker Prime 200W Power Bank review for the newer, higher-output alternative, and our best portable chargers guide for how it stacks up against banks from other brands. If you are buying this specifically to keep a laptop like the Framework Laptop 16 topped up on the road, confirm your laptop supports PD 3.1 before assuming you will hit the full 140W.
Verdict: Buy it if the price is right, otherwise compare first
The Anker 737 still does its core job well: high capacity, real laptop-charging headroom, and a useful display, in a bank that regularly sells below its original list price. Buy it when you find it discounted to $90 to $110 and you genuinely need laptop-level output on the go.
If you want the lightest possible carry with a built-in cable, get the newer Anker Laptop Power Bank (A1695) instead. If raw capacity and output matter more than price, the Anker Prime 200W is the newer flagship. For most people who just want a proven, high-output bank at a fair price, the 737 remains a reasonable buy.

The Verdict
The Anker 737 is still a capable high-output power bank: 24,000mAh, 140W across its USB-C ports, and enough headroom to top up a laptop. It is not Anker's newest design, so most buyers should compare it against the Anker Prime 200W and the newer Anker Laptop Power Bank (A1695) before buying.
