Overview
This is Anker's 20,000mAh power bank with a built-in USB-C cable and 87W of total output split across three ports, model A1383. It is aimed at travelers who want to charge a phone, tablet, and laptop from one unit without packing a separate cord.
The built-in cable is the feature that shows up most in how people actually use this bank: it removes the need to carry a spare cord for Android devices and for recharging the bank itself. Anker splits the 87W across three ports rather than dedicating it to one, so charging three devices at once means each gets less than the peak 65W a single device can pull.
- 20,000mAh capacity, model A1383
- Built-in USB-C cable, no separate cord needed for many devices
- 87W total output across three ports, up to 65W to one device
- Approved for airline travel
Who it's for
Frequent travelers, backpackers, and anyone charging a laptop, phone, and camera gear away from outlets for a full day or more. It is not the pick for someone who wants a light, pocket-sized bank for a single phone.
Pros and cons
- Built-in USB-C cable means one less cord to pack
- Charges a laptop, phone, and tablet from one unit across three ports
- 20,000mAh capacity covers multiple full phone charges on one trip
- Noticeably heavier than smaller banks, a tradeoff buyers repeatedly flagged
- Splitting power across three ports at once lowers what each device receives
- Recharging the bank itself takes real time without a fast charger
Performance notes
The built-in USB-C cable can recharge the bank itself or charge an Android phone directly, while a separate certified cable is recommended for Apple devices given differing charging specifications. A single device can draw up to 65W, a 14-inch MacBook Pro reaches roughly 50% in under 40 minutes, and the bank itself recharges in about 1.5 hours from a 65W charger. It is rated for airline travel.
