Overview
A 5 foot flat-plug power strip that adds three AC outlets and three USB ports, including one USB-C, in an ultra-thin cube design meant for travel, dorms, and tight spots behind furniture.
At 0.31 inch thick, the plug is built to sit flush against a wall or hide behind a nightstand or sofa, and the listing explicitly notes there is no surge protection, which the seller frames as an advantage since surge protectors are often restricted on cruise ships. The combined USB output is capped at 5V/3A (15W) across all three ports, not per port.
- 0.31 inch ultra-thin flat plug
- 3 AC outlets + 2 USB-A + 1 USB-C
- 5 ft cord length
- No surge protection, by design
Who it's for
Suits travelers, cruise passengers, and dorm or small-office setups needing to charge several devices from one outlet in a tight space. Not a fit for anyone wanting surge protection or fast per-port USB charging, since output is shared and there is no protection circuit.
Strengths and trade-offs
Drawn from this product's published specifications.
- Ultra-thin 0.31 inch flat plug fits tight spaces
- 3 AC outlets plus 3 USB ports including USB-C
- No surge protection, allowed on cruise ships
- 5 ft cord for flexible placement
- USB output is shared at 5V/3A total, not per port
- No surge protection for the AC outlets
Performance notes
The 3 AC outlets and 3 USB ports (2 USB-A, 1 USB-C) share a combined 5V/3A output, so multiple devices charging at once split that 15W rather than each getting full speed. Because it carries no surge protection, it avoids the restriction many cruise lines place on surge protectors, which the listing calls out directly.
