You’re carrying three chargers and a power bank. One for phone, one for laptop, one for earbuds—plus a battery pack that can only charge phones. Your bag is a cable disaster.
What if one device could charge everything at full speed?
Our verdict: The Anker 737 Power Bank is the best high-capacity portable charger, delivering enough power to charge laptops while remaining TSA-approved for air travel.
Our Pick: Anker 737 Power Bank
Quick take: 24,000mAh capacity, 140W USB-C output that charges MacBook Pro at full speed, smart digital display showing watts and time remaining, and recharges itself in 1.5 hours. The do-everything power bank.
Best for:
- Travelers who charge laptops on the go
- Remote workers at coffee shops
- Anyone wanting to consolidate charging gear
- Power users with multiple devices
Skip if:
- You only charge phones (smaller banks are cheaper)
- Weight matters more than capacity
- Budget is tight ($110 is premium pricing)
Why the Anker 737 Changes the Game
140W USB-C Output
Most power banks max out at 18-30W—enough for phones, useless for laptops. The 737 delivers 140W through USB-C, matching your MacBook’s wall charger speed.
One USB-C port charges your laptop. The other charges your phone. Simultaneously. At speed.
Smart Digital Display
The built-in display shows:
- Exact wattage being delivered
- Time remaining until empty
- Time remaining until full (when recharging)
No guessing. No wondering if it’s actually charging.
TSA-Approved Capacity
At 87.68Wh, the 737 is just under the 100Wh TSA limit for carry-on lithium batteries. You get maximum legal capacity without the airport hassle.
Fast Self-Recharging
With a 140W charger, the 737 goes from empty to full in about 1.5 hours. No more overnight charging—plug it in while you shower and it’s ready.
The Honest Downsides
It’s Heavy
At 1.3 pounds, you’ll notice it in your bag. Physics applies—energy density has limits. If you prioritize weight over capacity, look at the Anker 735 (smaller, lighter).
Premium Price
$110 is expensive for a power bank. You’re paying for the 140W output capability and premium build. Budget-conscious users can find phones-only options for $30-40.
Brick-Like Shape
The rectangular design doesn’t slip into pockets. It’s a bag item, not a pocket item.
Who Should Buy the Anker 737
Perfect for you if:
- You travel with a laptop
- Multiple devices need charging daily
- You value consolidating gear
- Flight-ready capacity matters
Consider alternatives if:
- You only charge phones (Anker 335 at $40)
- Weight is critical (Anker 735 at 12oz)
- Budget is limited
How It Compares
| Feature | Anker 737 | Anker 735 | Apple MagSafe Battery |
|---|---|---|---|
| Capacity | 24,000mAh | 12,000mAh | 1,460mAh |
| Max Output | 140W | 65W | 15W |
| Weight | 1.3 lbs | 0.75 lbs | 0.25 lbs |
| Laptop Charging | Yes | Slow | No |
| Price | $110 | $60 | $99 |
The 737 is the only option for full-speed laptop charging. The 735 is better for phone-only users who want some laptop emergency power. Apple’s option is iPhone-only.
The Bottom Line
The Anker 737 Power Bank is the ultimate portable charging solution for anyone who travels with a laptop. The ability to charge a MacBook Pro at full speed while simultaneously charging a phone eliminates the need for multiple chargers.
It’s heavy and expensive. But if laptop charging matters, nothing else compares.
