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.

| 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.
