High-Capacity 20,000 mAh Portable Power Bank

Reliable USB-C Power Bank for Phones, Tablets & More

This 20,000 mAh portable charger gives you the power you need when you’re on the go. It’s built with both USB-C and USB-A ports, letting you charge multiple devices—smartphones, tablets, earbuds, even handheld gaming systems—without scrambling for cables or adapters.

Key Features & Everyday Benefits

Triple-Port Charging: With one USB-C and two USB-A outputs, you can power up to three devices at once—great for when you’re traveling with family or managing multiple gadgets.

Fast Charging Support: The USB-C port handles fast charging protocols (5 V, 3 A / 9 V, 2 A / 12 V, 1.5 A), reaching up to 18 W output. That means your phone recovers battery more quickly. The USB-A ports also support up to 12 W each. (Total shared output is also rated for optimal distribution.)

Generous Capacity: At 20,000 mAh, this power bank can provide several full charges for most smartphones. That’s ideal for weekend travel, long commutes, or extended outdoor use.

Compact, Travel-Friendly Design: Despite its high capacity, the charger remains slim enough to slip into a backpack, purse, or carry-on. It also meets TSA airline safety standards for lithium battery packs.

Smart Protection & Reliability: Built-in safeguards guard against overcharging, overcurrent, temperature extremes, and short circuits—keeping your devices safe every time.
