Anker 737 Power Bank Review
The Anker 737 is a 24,000mAh power bank that delivers genuine 140W laptop-class charging — territory most portable chargers simply can’t touch at under $100. It trades pocketability for raw capability, making it a power-user tool rather than an everyday-carry accessory.

Our Take
The first thing you notice is the weight — at 630 grams, the 737 feels less like a phone accessory and more like a small brick of stored energy, which is exactly what it is. Plug in a MacBook and watch the smart display report real-time wattage flowing out, and the heft suddenly makes sense: this thing replaces a wall outlet, not a keychain charger. It’s the rare power bank that makes you stop guessing whether your devices are actually fast-charging.
Why It’s Useful
| FEATURE | WHAT YOU GET | REAL-WORLD IMPACT |
|---|---|---|
| Battery Capacity | 24,000mAh lithium polymer | Up to 4.13 full charges for an iPhone 16 Pro, or 1.33 charges for a 2024 13″ iPad Pro |
| Max Output | 140W total (USB-C up to 140W, USB-A up to 18W) | Fast-charges USB-C laptops like a MacBook — not just phones and earbuds |
| Ports | 2× USB-C + 1× USB-A | Charge a laptop, phone, and earbuds simultaneously from one bank |
| Recharge Speed | 140W USB-C input | Refills from empty in about 1 hour with a 140W PD wall charger (not included) |
Key Highlights
Pros and Limitations
✓ What We Like
- Serious power reserve — strong enough for phones, tablets, laptops, gaming laptops, and multi-day trips, not just top-ups.
- The display removes guesswork. Real-time wattage and recharge estimates are the most-praised feature after capacity itself.
- One bank replaces several chargers — MacBook, phone, tablet, and earbuds from a single unit.
— Limitations
- It’s heavy and bulky. At 630g and over six inches long, this lives in a bag, not a pocket.
- Some units develop charging faults — a minority of buyers report units that stop charging or shut off unexpectedly.
Who It’s For
- 🏠 Remote workers, students, and frequent travelers who need to keep a USB-C laptop and a phone alive away from outlets — and who’d rather carry one capable bank than a charger for each device.
- ✈️ Power users with USB-C gaming handhelds or laptops who want verified fast charging at under $100, with the display to prove it’s working.
Who Should Skip It
- ⚡ Anyone who wants a light, pocketable charger for emergency phone top-ups — at 630g, this is overkill in both capacity and bulk.
- ⚙️ Buyers who need guaranteed set-and-forget reliability and have zero patience for potential troubleshooting down the road.
