Choosing the Right Power Bank
Power banks range from lipstick-sized emergency chargers to briefcase-sized beasts that can charge a laptop multiple times. The right one depends on what devices you charge, how much power you need, and how portable it must be.
We tested ten power banks and narrowed it down to the five best across different use cases.
1. Anker Prime 27,650mAh — Best Overall
Price: $129 | Capacity: 27,650mAh | Rating: 9.4/10
The Anker Prime is the most versatile power bank you can buy. 250W total output charges a MacBook Pro, iPhone, and Apple Watch simultaneously. The smart display shows real-time wattage, remaining capacity, and estimated charge time for each connected device.
What makes it special: 140W USB-C output charges a MacBook Air from 0-50% in 30 minutes — the same speed as Apple's wall charger. Two USB-C ports and one USB-A port handle three devices at once. The 170W USB-C input recharges the power bank itself in just 35 minutes.
For travel: TSA-approved at 99.54Wh (just under the 100Wh limit). Weighs 1.4 lbs — comparable to a can of soda.
Best for: Laptop users, multi-device chargers, and frequent travelers who need serious portable power.
2. Ugreen Nexode 25,000mAh — Best Value
Price: $69 | Capacity: 25,000mAh | Rating: 9.0/10
Ugreen delivers 85% of the Anker Prime's capability at 53% of the price. 200W total output with 140W max single-port, two USB-C and one USB-A port, and a clear display showing charge status.
Performance: Charged an iPhone 16 from 0-50% in 18 minutes (matching Apple's fastest charger). Charged a MacBook Air from 0-50% in 33 minutes. The difference from the Anker Prime is minimal in real-world use.
Build quality: GaN technology keeps it compact and cool during high-power charging. The matte finish resists fingerprints and provides a secure grip.
Best for: Budget-conscious users who want laptop-charging capability without paying premium prices.
3. Anker Nano Power Bank 10,000mAh — Best Compact
Price: $29 | Capacity: 10,000mAh | Rating: 8.8/10
The Anker Nano is barely larger than a credit card but packs enough power to charge most phones twice. The built-in foldable USB-C connector means no cables needed — just plug it directly into your phone.
Portability: At 7.4 oz and pocket-sized dimensions, you will actually carry this every day. The foldable connector design eliminates the need to carry a separate cable.
Charging speed: 30W USB-C output charges modern phones at near-maximum speed. The built-in connector charges the connected device while the USB-C port charges a second device.
Best for: Daily carry. The power bank you actually have with you when you need it.
4. Baseus Blade 20,000mAh — Thinnest Laptop Charger
Price: $89 | Capacity: 20,000mAh | Rating: 8.7/10
At just 0.7 inches thick, the Baseus Blade slides into a laptop sleeve alongside your MacBook. Despite the thin profile, it delivers 100W USB-C output — enough to charge any laptop.
Design: The slim form factor is the entire selling point, and it delivers. At 0.7 inches thin and weighing 1.1 lbs, it is the most backpack-friendly laptop power bank available.
Performance: 100W output charges a MacBook Air at full speed. 65W charges most Windows ultrabooks. The LED display shows exact percentage and charging wattage.
Trade-off: 20,000mAh provides about 70% charge for a MacBook Air or one full charge for most phones with power to spare. Not as much capacity as the Anker Prime, but significantly more portable.
Best for: Minimalists and ultrabook users who want the thinnest possible laptop power bank.
5. Anker MagGo 6,600mAh — Best for iPhone (MagSafe)
Price: $32 | Capacity: 6,600mAh | Rating: 8.5/10
The MagGo magnetically snaps onto the back of any iPhone 12 or later and wirelessly charges at 15W while you use your phone. No cables, no plugging — just snap it on and go.
MagSafe experience: The magnetic alignment is strong enough to hold during normal use (texting, browsing, taking photos) but releases cleanly when you pull. The built-in kickstand props your phone at a comfortable angle while charging.
Capacity: 6,600mAh provides about 1.2 full charges for an iPhone 16. Not enough for a full day of heavy use, but perfect as an afternoon boost or emergency backup.
Charging speed: 15W wireless is slower than wired charging, but the convenience of cable-free magnetic charging is worth the trade-off for most iPhone users.
Best for: iPhone users who want the most convenient portable charging experience possible.
Comparison
| Power Bank | Price | Capacity | Max Output | Weight | Best For | |-----------|-------|----------|-----------|--------|----------| | Anker Prime | $129 | 27,650mAh | 250W | 1.4 lbs | Overall | | Ugreen Nexode | $69 | 25,000mAh | 200W | 1.3 lbs | Value | | Anker Nano | $29 | 10,000mAh | 30W | 0.46 lbs | Compact | | Baseus Blade | $89 | 20,000mAh | 100W | 1.1 lbs | Thin laptop | | Anker MagGo | $32 | 6,600mAh | 15W | 0.37 lbs | iPhone MagSafe |
How to Choose
Phone only: Anker Nano 10,000mAh ($29) — small, affordable, cable-free.
Phone + tablet: Ugreen Nexode 25,000mAh ($69) — plenty of power at a great price.
Laptop charging: Anker Prime ($129) or Baseus Blade ($89) depending on whether you prioritize capacity or thinness.
iPhone MagSafe: Anker MagGo ($32) — magnetic convenience is addictive.
The best power bank is the one you carry. A massive power bank left at home is useless. Choose based on what you will realistically bring with you every day.
