Anker Wall Charger 300J Surge Protector 10-in-1 Outlet Extender - Slim

In this review of the Anker Wall Charger 300J Surge Protector, the bottom line is simple: this is a compact, reliable outlet extender built for people who need to charge multiple devices from a single wall location without bulk. It combines a slim 1.19 in profile with a thoughtful 10-in-1 layout that keeps chargers flush to the wall and reduces cable clutter. The single biggest reason to buy is the combination of wide-spaced AC outlets and four USB ports, including a 20W USB-C PD port that delivers genuinely fast charging for modern phones.

Key Features

• Slim low-profile design: The 1.19 in thickness keeps the unit close to the wall so it stays securely fastened and avoids sticking out into tight spaces.
• 10-in-1 charging: Six AC outlets plus two USB-A and two USB-C ports let you power a mix of laptops, chargers, and USB devices simultaneously without a bulky power strip.
• 20W USB-C fast charge: The USB-C1 port supports 20W PD charging capable of taking an iPhone 15 from 0 to around 53% in 30 minutes for quick top-ups.
• Wide-spaced and angled outlets: Angled and well-spaced AC outlets make it easier to fit larger power bricks and keep adjacent plugs from blocking each other.
• Travel-friendly footprint: The compact, slim form factor and integrated surge protection make it a practical desk or dorm charging station that is easy to install.

Who It's For

The Anker 300J fits users who need a neat wall-mounted charging hub for a home office, dorm room, or bedside setup and who value a low-profile design that keeps bulky plugs close to the wall. It is especially useful for households with multiple phones, tablets, and accessories that benefit from dedicated USB ports alongside AC outlets.

Those who need a heavy-duty industrial power strip, very long extension cord, or advanced surge suppression beyond basic protection should look elsewhere; likewise users who require more than 6 AC outlets spread across a long reach will want a different product. For typical home and small-office charging needs, this unit strikes a practical balance.

Pros & Cons

Pros

• Compact, ultra-thin profile that sits close to the wall and reduces protrusion.
• Multiple USB ports and six AC outlets let several devices charge at once without adapters.
• 20W USB-C PD delivers noticeably faster phone charging from the USB-C1 port.
• Well-spaced, angled outlets accommodate larger plugs and adapters easily.

Cons

• Limited to six AC outlets; users needing many more AC sockets or extended cord length will need a full power strip.
• Only one USB-C port provides the 20W fast-charge speed; the other ports are useful but not as fast.
