Our Take
The Anker 737 is a serious mid-range power bank that sits comfortably between Anker's budget models and their premium range. It's built for people who actually move around a lot – commuters, photographers, remote workers, anyone who needs their devices topped up throughout the day without carrying a brick in their bag. If you've ever found yourself hunting for a socket at 3pm, this is the sort of thing that stops that becoming your life.
You're getting a 24,000mAh battery here, which sounds impressive until you realise what it actually means: enough juice to fully charge most modern phones three times over, or a tablet once with plenty left in the tank. The real headline is the dual USB-C and dual USB-A setup with 140W combined output – that means you can genuinely charge multiple devices at full speed simultaneously, which matters if you've got a phone, tablet, and laptop competing for power. It's got Anker's PowerIQ 3.0 technology built in, so it automatically detects what you've plugged in and delivers the right power to each port. The casing is a mix of plastic and metal, feels solid without being heavy, and it comes in at around 570g – hefty enough to feel substantial, light enough you won't resent carrying it.
Against comparable alternatives like the Baseus 100W models or Anker's own 535 Power Bank, the 737 lands in a sweet spot if you need multi-device charging without the heft of a full 65W laptop charger. Before you order, check the exact cable bundle – Anker occasionally tweaks what comes in the box between regions, and you'll want to confirm USB-C cables are included. It's widely available from UK retailers, and Anker's UK warranty is straightforward, so there's no funny business to worry about on that front.
Key Features
24,000mAh capacity with 140W combined output across four ports (2x USB-C, 2x USB-A)
PowerIQ 3.0 intelligent charging detection with support for fast-charging protocols including USB Power Delivery and Quick Charge
Dimensions approximately 157 × 65 × 32mm; weight around 570g for portability without sacrificing capacity
Input via dual USB-C sockets with 65W maximum input charging speed (recharges the bank itself in roughly 30 minutes with appropriate charger)

Our Verdict
Buy this if you're regularly charging multiple devices and want something genuinely fast that doesn't weigh a ton. Skip it if you only charge one phone occasionally or need something pocket-sized – you'll get better value from a smaller, single-port model.
