Anker 737 Power Bank: Quick Specs
Key Features: What Makes the Anker 737 Stand Out?
1. 140W Total Output — Charges Laptops at Full Speed
The Anker 737’s biggest selling point is its 140W maximum output via USB-C. This is the highest output available in any consumer power bank, and it means you can charge a MacBook Pro 14″ or a Dell XPS at their rated speeds — not the slow trickle you get from most power banks. Even power-hungry laptops see meaningful charge progress within 30 minutes. If you’re working remotely from cafes or co-working spaces (check our list of best remote job tools for 2026), this is a game-changer.
2. 24,000mAh — Truly Massive Capacity
24,000mAh is enough to charge an iPhone 15 approximately 5 times, a Samsung Galaxy S24 about 4 times, or a MacBook Air M3 nearly 1.5 times. That’s a full day of work without ever needing a wall outlet — ideal for long flights, remote work sessions, or travel days where outlets are scarce.
3. Charge 3 Devices Simultaneously
With 2 USB-C ports and 1 USB-A port, you can charge your laptop, phone, and earbuds all at the same time. The power bank intelligently distributes wattage across ports based on what’s connected — so your MacBook gets priority power while your phone gets a top-up on the side. Pair it with wireless earbuds like the smart home tech for a complete mobile workspace.
4. Smart Digital Display
Unlike most power banks that use vague LED dot indicators, the Anker 737 has a precise digital display showing exact battery percentage. You’ll always know exactly how much charge is left — no guessing whether those 2 dots mean 40% or 60%. It’s a small feature that makes a huge practical difference.
5. Ultra-Fast Self-Recharge
Using a 140W USB-C charger, the Anker 737 recharges itself in just ~1.6 hours. That’s faster than many smaller power banks. Even at 65W input, it recharges in about 2.5 hours — so overnight charging easily keeps it topped up and ready.
6. Airline Carry-On Approved
At 87Wh, the Anker 737 falls under the FAA’s 100Wh limit for carry-on batteries, making it fully approved for flights. This is a deliberate design decision by Anker — maximum capacity within airline regulations. No checked baggage required.

- Content creators & AI enthusiasts — power your AI gadgets and devices all day without a wall outlet
- Power users with multiple devices — laptop + phone + earbuds charging together
- Emergency backup power — enough capacity to last through power outages for critical devices
Real-World Experience
In daily use, the Anker 737 earns its premium reputation. The digital percentage display is genuinely useful — it’s one of those features you don’t realize you needed until you have it. No more guessing if you have enough charge for the day; just check the display and know instantly.
The 140W charging is noticeably faster than typical USB-C power banks. Plugging in a MacBook Pro that’s at 20% sees real progress within 20–30 minutes — around 30–40% charge added. For a power bank, that’s remarkable.
The weight (771g) is the main trade-off. This is not an ultralight travel accessory — it’s a serious power station in a portable form. If you primarily need a lightweight phone charger, a smaller 10,000mAh bank might serve you better. But if you need laptop-level power in a carry-on, nothing else comes close.
Frequently Asked Questions
Can the Anker 737 charge a MacBook Pro?
Yes — the Anker 737 outputs up to 140W from its primary USB-C port, which is sufficient to fully power and charge the MacBook Pro 14″ (96W) and MacBook Pro 16″ (140W) at rated speeds. It will charge the MacBook Air M3 (67W) even faster.
Is the Anker 737 allowed on planes?
Yes. At 87Wh, the Anker 737 is below the FAA’s 100Wh carry-on limit for lithium batteries. It can be carried in your hand luggage on all major airlines without restrictions.
How many times can the Anker 737 charge an iPhone?
Approximately 5 full charges of an iPhone 15, or 4 full charges of an iPhone 15 Pro Max. For Android, expect about 4–5 charges for most flagship phones.
Does the Anker 737 support wireless charging?
No — the Anker 737 does not support wireless (Qi) charging. All charging is via the USB-C and USB-A ports. If wireless charging is a priority, consider the Anker 622 Magnetic Battery (MagSafe compatible) though it has much lower capacity.
What charger should I use to recharge the Anker 737?
For fastest recharging, use a 140W USB-C GaN charger. Anker makes the 747 GaN charger (140W) that pairs perfectly with the 737. Standard 65W USB-C chargers also work but will take ~2.5 hours to fully charge it instead of ~1.6 hours.
Is the Anker 737 worth it vs cheaper alternatives?
If you need to charge a laptop on the go, yes — absolutely. Cheaper 20,000mAh power banks top out at 65W, which trickle-charges most laptops. The 140W output is the Anker 737’s defining feature and justifies the premium price for laptop-dependent users.

The Anker 737 Power Bank is the best high-capacity portable charger for professionals who need laptop-level power in their bag. The 140W output, 24,000mAh capacity, precise digital display, and airline approval make it an unmatched choice for anyone who works on the go.
It’s not cheap and it’s not light — but it delivers on every promise. For remote workers, frequent travelers, and power users with multiple devices, this is the power bank you buy and never look back from.
