Anker 737 Power Bank Review: One Battery, Every Device

Anker 737 Power Bank review banner with category label and star rating

Quick verdict

The Anker 737 is the power bank to get when one battery has to run everything: phones, tablets, and even laptops that charge over USB-C. Its 140-watt maximum output is the headline, but the small digital display – showing exact input and output wattage in real time – is the feature you end up using every day. It is heavy and priced like a small laptop charger, so casual phone top-ups have better options.

Key specs

Capacity 24,000 mAh (86 Wh)
Max output 140 W (single USB-C port)
Ports 2 × USB-C, 1 × USB-A
Display Smart digital display: remaining charge, in/out wattage, time to full
Weight About 625 g (1.4 lb)
Flight-safe Yes – 86 Wh, under the 100 Wh carry-on limit

What we like

  • One port charges a 16-inch laptop at full speed while the other two handle a phone and earbuds case.
  • The wattage display makes it obvious whether a cable or charger is actually delivering what the box promises.
  • Recharges itself surprisingly fast on a 100 W wall charger – a coffee break is enough for most of a day of use.
  • Build quality feels like Anker’s best: dense, tight tolerances, no rattling ports.

What could be better

  • At roughly 1.4 pounds it is a real weight decision in a daypack; this is not a pocket power bank.
  • Street price usually sits near the hundred-dollar mark, several times what a phone-only battery costs.
  • Sustained high-draw charging (a laptop plus a phone together) makes the case noticeably warm.

Who it is for – and who should skip it

Buy it if you travel with a USB-C laptop, shoot on mirrorless cameras, or simply want one charger to replace three. Skip it if you only need two or three emergency phone recharges per week: a 10,000 mAh bank a third of the price does that job with none of the weight.

How it compares

  • Anker Prime 27,650 mAh (250 W) – more capacity and power for notably more money and weight; the better pick for desktop-remote workers.
  • Ugreen 145 W banks – very close on specs, often a little cheaper, with a plainer display and slightly looser build.
  • Mophie Powerstation Pro – nicer fabric finish, lower peak output, and usually less value per watt.

Price and where to buy

Expect a street price of roughly $95–$130 depending on sales – Anker discounts it often, so a launch-week purchase is rarely the cheapest one. Check the current price on Amazon (affiliate link – see our affiliate disclosure).

I have spent the last twelve years pulling consumer tech apart – sometimes literally – to find out what is actually worth your money. Before starting Freakin Review, I ran product QA and return-rate analysis for a Dallas-based electronics retailer, where thousands of returned devices a month taught me one lesson: spec sheets lie more often than reviewers do. I lead our testing bench in Austin, where every power bank, pair of earbuds, and computer peripheral goes through a standardized 10-point routine – real measurements, weeks of daily use, and no free sample we are afraid to criticize. When a product fails, I say so, even when the affiliate link pays less.
