The 7 best portable power banks on Amazon, ranked
1. Anker 737 Power Bank (PowerCore 24K) — best overall
Best for: heavy users who need to recharge a phone and top off a laptop multiple times
With 24,000mAh of capacity and 140W total output, the PowerCore 24K can recharge a phone several times over or top off a laptop through USB-C. Its smart digital display shows exact battery percentage and real-time charging wattage, which takes the guesswork out of tracking remaining power.
2. Anker MagGo Power Bank — best MagSafe charging
Best for: iPhone owners who want cable-free, snap-on charging
The MagGo attaches magnetically to the back of a Qi2-compatible iPhone for cable-free wireless charging, while still offering a USB-C port for faster wired charging when needed. Its slim profile means it doesn't add much bulk even when left attached during the day.
3. Zendure SuperTank — best high-capacity travel power
Best for: travelers and campers who need to power laptops and multiple devices
At 26,800mAh with 100W USB-C Power Delivery, the SuperTank has enough capacity and output to charge a laptop, not just a phone, making it a solid pick for multi-day trips. Its four ports let you charge several devices simultaneously without juggling cables.
4. Mophie Powerstation Pro AC — best laptops and full-size electronics
Best for: charging laptops and full-size electronics away from an outlet
This power bank includes a built-in AC wall outlet in addition to USB ports, so it can run laptop chargers and other electronics that need a standard plug rather than USB. At 27,000mAh, it holds enough charge for extended use away from a wall outlet.
5. Baseus Blade 2 Ultra-Slim Power Bank — best slim everyday carry
Best for: slipping into a bag or pocket without added bulk
The Blade 2 is built to be carried daily, with a slim profile that fits easily into a laptop bag or even a jacket pocket despite offering 12,000mAh of capacity. It supports 65W fast charging, which is enough to charge a laptop or quickly top off a phone.
6. Anker Nano Power Bank — best built-in cable convenience
Best for: minimalist everyday carry without a separate charging cable
The Nano Power Bank has a built-in USB-C cable that folds into the unit, so there's no separate cord to lose or tangle in a bag. At 10,000mAh with 30W output, it's sized for topping off a phone once or twice rather than heavy multi-device use.
7. INIU Portable Charger — best the price
Best for: shoppers who want reliable charging without spending much
INIU's compact charger offers 22.5W fast charging and 10,000mAh of capacity at one of the more affordable price points in this category. It's a straightforward, no-frills option for anyone who just needs a dependable backup battery for a phone.

Frequently asked questions
Which portable power bank should I buy in 2026?
For most people, the Anker 737 Power Bank (PowerCore 24K) is the best portable power bank to buy, offering enough capacity to recharge a phone multiple times plus a smart display that shows exact battery percentage and charging wattage.
How many mAh do I need in a power bank?
A 10,000mAh power bank typically recharges a phone about two to three times, while a 20,000mAh or larger power bank, like the Anker 737 or Zendure SuperTank, can recharge a phone several times or help top off a laptop.
Can I bring a portable power bank on a plane?
Yes — the TSA allows portable power banks in carry-on luggage as long as they're under 100Wh, which covers every power bank in this list, but they are not permitted in checked bags.
Is a MagSafe power bank worth buying?
A MagSafe (Qi2) power bank like the Anker MagGo is worth it if you own a compatible iPhone and want cable-free charging that snaps securely to the back of your phone, though it typically charges slower than a wired connection.
