All-in-One Travel Charger

This 3-in-1 device combines a 10000mAh power bank, a foldable wall plug and a built-in USB-C cable. It suits travellers who want one compact unit instead of carrying separate chargers and cables. The integrated design reduces the number of items to pack for short trips.

Thermals and Power

The unit delivers up to 30W two-way fast charging whether plugged in or running on battery. An iPhone 15 Pro reaches 50% in about 25 minutes. Slight warmth during use is normal and stays within IEC62368 limits. Conversion losses mean the usable capacity is roughly 5500mAh to 7000mAh.

Connectors and Daily Use

A built-in USB-C cable handles most modern phones and laptops, while the USB-C port allows a second device to charge at the same time. Older iPhones before the 15 series need a separate USB-C to Lightning cable. The foldable plug stores flat, keeping the 4.25 × 2.01 × 1.22" form factor pocketable at 8.82 oz.

Questions about this item

How do I plug the Anker Nano A1637 into a wall outlet to charge it?

Unfold the built-in plug on the back of the unit and insert it directly into an AC socket; the 10,000mAh battery recharges at up to 30W without any extra cable.

What capacity loss should I expect over time with the 10,000mAh cell?

The supplier notes a 30% to 45% energy loss during conversion, so a fully charged pack delivers an estimated 5,500mAh to 7,000mAh to devices.

How hot does the power bank get during sustained 30W output?

Slight warming is normal from conversion losses; the unit meets IEC 62368 temperature limits under load.
