Anker 737 Power Bank Review: Full-Day Capacity, Bulkier Trade-Off

The Anker 737 Power Bank is a higher-capacity option aimed at people who need a real day’s worth of backup charge, not just a top-up — the kind of power bank you reach for when you know you’ll be away from an outlet for a full day of heavy phone and laptop use, not just an emergency 20% boost.

Rating: 4/5
Best for: Frequent travelers and heavy phone-and-laptop users who want genuine multi-device, multi-charge capacity in one power bank.
Bottom line: A bulkier, heavier power bank than slimline alternatives, but the trade-off buys real capacity and a genuinely useful display most competitors skip.

Anker 737 Power Bank key specs

Build and portability: the size trade-off

The case is solid without feeling overbuilt — the digital display showing exact remaining charge percentage and wattage output is more useful day to day than the usual four-LED-light guess most power banks still ship with. That accuracy matters when you’re deciding whether it’s worth grabbing on your way out the door.

It’s noticeably bulkier and heavier than slimline power banks in the same price range — a direct trade-off for the higher capacity. If you mainly need an emergency top-up rather than a full day’s backup, a smaller, lighter power bank will serve you better and take up less bag space.

Charging speed and capacity in real use

The 737 fast-charges phones and laptops via USB-C at a genuinely useful speed, and can charge two or three devices simultaneously without a dramatic drop in any single one’s speed — useful if you’re topping up a phone and a laptop at the same time on a long travel day. Recharging the power bank itself from empty is faster than most competitors in this capacity class thanks to USB-C PD input.

At 24,000mAh, it comfortably covers a full day of heavy phone use with charge to spare, or a couple of full phone charges plus a meaningful laptop top-up. Real-world usable capacity on power banks this size typically runs somewhat below the rated figure due to voltage conversion losses — normal across the category, not specific to this model.

Durability in Kuwait heat

Lithium-ion power banks lose capacity faster with sustained heat exposure — a real consideration given how often a power bank ends up in a car glovebox here. Anker doesn’t publish Kuwait-specific heat data beyond its standard operating range, so the safest approach with any power bank, this one included, is to avoid leaving it in a hot car longer than necessary.

Pros and cons

Pros

• Genuine full-day capacity for heavy phone and laptop use.
• Digital display shows exact charge and wattage, not a rough LED guess.
• Charges up to 3 devices simultaneously without a dramatic speed hit.
• Faster-than-average recharge time via USB-C PD.

Cons

• Noticeably bulkier and heavier than slimline power banks.
• Overkill if you only need an occasional emergency top-up.
• Like all lithium-ion power banks, sustained heat exposure shortens its lifespan.

Who should — and shouldn’t — buy the Anker 737?

You should buy it if…

You travel frequently, work away from outlets for full days, or regularly need to charge a phone and a laptop from the same power bank. The digital display is also a genuine quality-of-life upgrade if you’ve been guessing with LED indicators until now.

You should skip it if…

You just want a small emergency top-up for occasional low-battery moments — a slimmer, lighter, cheaper power bank will serve that use case better and take up less space in a bag or car console.

FAQ

How long does the Anker 737 Power Bank last on a single charge?

At 24,000mAh, it comfortably covers a full day of heavy phone use with charge to spare, or a couple of full phone charges plus a meaningful laptop top-up — real-world figures depend on what you’re charging and how fast.

Can the Anker 737 charge a laptop?

Yes — its up-to-140W output via USB-C PD is enough for most USB-C laptops, though check your specific laptop’s charging requirements against the port’s actual per-port wattage limit.

Is the Anker 737 safe to leave in a hot car?

Not ideal for extended periods — like any lithium-ion power bank, sustained heat exposure shortens its lifespan. Avoid leaving it in a hot car glovebox longer than necessary.

How many devices can the Anker 737 charge at once?

Up to three, across its dual USB-C and single USB-A ports, without a dramatic speed drop on any individual device.

Final verdict

The Anker 737 Power Bank trades portability for genuine capacity, and does it well — the digital display alone is a meaningful upgrade over guess-based LED indicators, and the fast simultaneous charging across three devices makes it a real travel-day companion rather than just an emergency backup.

If you need a slim everyday-carry power bank, look elsewhere — but if you regularly need to keep a phone and laptop running through a full day away from outlets, this is a strong pick, with the usual lithium-ion heat caveat that applies to every power bank in Kuwait’s climate, not just this one.
