Anker 20W USB C Power Strip with 3 Outlets and USB Charging

In this review of the Anker 20W USB C Power Strip, the bottom line is simple: it is a compact, travel-friendly power cube for people who need multiple AC outlets plus a USB-C fast charge in a very small footprint. The reviewer found it especially useful for dorm rooms, small desks, and travel where space is limited but a mix of wall outlets and USB ports is needed. The single biggest reason to buy is the combination of three AC outlets and a 20W USB-C port in roughly the size of a tennis ball, which keeps a phone and a few devices powered without a bulky strip.

Key Features

• All-in-One Power: Three AC outlets plus two USB-A ports and one 20W USB-C port let you run multiple devices from a single compact cube.
• Compact Size: At roughly 2.2 in by 2.2 in by 2.2 in, the power strip fits easily into luggage or a small bag for travel and dorm use.
• Fast USB-C Charging: The 20W USB-C port supports Power Delivery to charge recent iPhone models significantly faster than a 5W adapter.
• Safe Design: A 7-point safety system with fire-resistant materials, overload and short-circuit protection provides peace of mind when charging multiple devices.
• Long Cord: The included 5 ft extension cord gives flexibility for desktop and bedside placement without crowding the outlet.
• Warranty and Support: Anker includes an 18-month warranty and a connected equipment warranty to protect compatible devices.

Who It's For

This unit is ideal for students, travelers, and home office users who need multiple AC outlets in a small space and want at least one reliable USB-C fast charge option. It works well on a small desk, in a dorm room, or in a hotel where wall outlets are limited and you want to avoid a long traditional power strip.

It is less appropriate for users who need high-power USB-A Quick Charge support for certain phones or who expect full simultaneous USB-C PD speed when multiple ports are used. Some customers reported mixed performance from USB ports, so those requiring guaranteed multi-port high-speed charging should consider a larger unit.
