Anker 737 Power Bank Review (2026)
Anker 737 review: 120W output, 24,000mAh capacity, and a smart display. Strengths, limitations, and who should buy it.
Anker 737 Power Bank (PowerCore 24K)
A 24,000mAh high-wattage bank with a smart display for laptops and phones.
Our verdict
The Anker 737 is the best all-around power bank for people who charge laptops on the go. 120 W output covers nearly any portable computer, 24,000 mAh lasts for days of mixed use, and the smart display finally answers the eternal question of how much charge is actually left. It is heavy and expensive, and overkill if you only charge a phone. Buy it if your bag regularly carries a laptop.
What we like
- 120 W total output charges most laptops
- Smart display shows real-time wattage and time estimates
- 24,000 mAh capacity covers multiple devices
- Two USB-C ports plus USB-A for legacy devices
What to watch out for
- Heavy and bulky for pocket carry
- Premium price tier
- Takes a long time to recharge itself at full capacity
Who it is for
Remote workers, travelers, and students who need one bank that can charge a laptop, tablet, and phone.
Power and capacity
The headline numbers are 120 W total output and 24,000 mAh capacity. In practice that means most ultrabooks charge at full speed and larger laptops charge well, while phones and tablets barely dent the reserve. Two USB-C ports plus USB-A mean the laptop, phone, and earbuds can all charge at once, though total output is shared across ports.
The smart display
The small display shows input and output wattage in real time plus estimated time to full or empty. It sounds like a gimmick until you use it: knowing a laptop is actually drawing 65 W, or that the bank needs three more hours on the charger, removes the guesswork that plagues every other power bank. This is the 737's most underrated feature.
Size, weight, and tradeoffs
There is no way around it: this is a brick. It lives in a backpack or laptop bag, not a pocket, and it takes hours to recharge itself fully even with a high-wattage wall charger. You are trading portability for capability. If your trips are phone-only, the Nitecore NB10000 Gen 3 gives you the essential capacity at a fraction of the weight.

Questions, answered
Can the Anker 737 charge a MacBook Pro?
Yes, for most models. 120 W output covers 14-inch MacBook Pro charging at full speed and charges larger models well. Check your specific model's adapter wattage to be sure.
How long does the 737 take to recharge?
It depends on your wall charger. With a 65 W or higher PD charger it recharges in a few hours; with a basic phone charger it takes much longer. The display shows the input wattage and estimated time remaining.
Can I take it on a plane?
In carry-on baggage, yes. Its capacity sits below the common 100 Wh airline threshold, but always check the Wh rating printed on your unit and your airline's current policy. Never put power banks in checked baggage.
