A Fantastic Power Solution for Older Homes with Limited Outlets ⚡🏡🔌
Size: 5FT, Color: White 2prong
Living in an older home often means dealing with outdated two-prong outlets and a frustrating lack of convenient charging options. This 2-prong extension cord and outlet adapter solves that problem beautifully by converting a polarized two-prong outlet into an incredibly versatile charging station with 11 AC outlets and 6 USB ports. 🏠✨📱 I have been using this type of power strip in areas where only older two-prong outlets are available, and it makes a tremendous difference. Instead of relying on multiple adapters and extension cords, everything can be plugged into one compact unit. 🔌💻📺 Whether charging phones, tablets, laptops, lamps, and other electronics, this power strip keeps everything organized and easy to access. The standout feature is the impressive 17-in-1 design. With 11 AC outlets and 6 USB ports, including 3 USB-C ports, it can power and charge a large number of devices simultaneously. 📱💻⌚🎮 The USB-C ports provide fast charging for many modern devices, which reduces the need for separate charging bricks and helps minimize clutter. I especially appreciate the thoughtful outlet layout. The three-row design provides generous spacing so larger power adapters do not block neighboring outlets. 🧠🔌👌 This makes it easy to use nearly every outlet at once, which is extremely useful for office setups, entertainment centers, and bedside charging stations. The five-foot extension cord offers excellent flexibility, and the flat angled plug fits neatly behind furniture without protruding too far from the wall. 🛋️📏✨ This is particularly helpful in tight spaces such as behind bookcases, sofas, and nightstands. The built-in mounting holes are another nice touch, allowing the unit to be securely attached to a wall or desk if desired. Safety features are also reassuring. With surge protection, overload protection, short-circuit protection, and fire-resistant construction, this power strip is designed to handle daily use with confidence. 🛡️⚡🔥 Knowing that connected electronics are protected adds significant peace of mind. For anyone living in an older house with two-prong outlets, this adapter offers a practical and highly efficient solution. It instantly modernizes outdated electrical access and provides abundant outlets and charging ports in one organized unit. 🏡🔌📱 Overall, this is an exceptionally useful power strip that combines convenience, charging versatility, and robust safety features. With 11 outlets, 6 USB ports, fast USB-C charging, and compatibility with older two-prong outlets, it is an excellent addition to any home, office, dorm room, or gaming setup. ⚡🏡🔌💻📱✨

2 prong to 3 prong power strip. Devices share common ground bus. Green light on switch. Compact plug
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
This power strip has no ground. It allows you to plug a 3 prong device into the strip which has a 2-prong plug going into your outlet. You'll want to make sure you understand the implications of that if you use this. For my use I'm using the power strip to have the convenience of using my 3 prong extension cords for ungrounded devices. The power strip is composed of the main body with 11 outlets plus 3 USB and 3 USB-C ports. There's a switch to turn on or off the power switch and the switch has a green light when turned on. On the back side are holes for optional surface mounting as well as the power ratings. The USB ports are all standard 5V ports. While the ground plug on the 3-prong outlets is not connected through the power cord the outlets on each side share a common bus on the power strip itself. Thus if any device plugged in on that side has power going into the ground prong it will energize the ground on all devices connected with a ground prong on that side. The body measures approximately 8.125" by 4.125" by 1.25" thick. I weighed the power strip with cord at 15.38 ounces. The power cord is approximately 4.9' long with a compact right angle plug. The plug is polarized meaning you cannot plug it in inside down. Looking at a 3-prong plug if the ground prong is at the bottom the cord goes down to the right at about a 45 degree angle. The plug is compact and you can plug 2 of these in on the same 2 outlet wall outlet. The cord is printed with the wire information and contains 2 16 AWG conductors. The rated power seems appropriate for the size of the power cord. The outlet looks and feels nice and handles a lot of devices.

Good value for a high quality product with some possible safety compromises
Size: 5FT, Color: White 2prong, Size: 5FT, Color: White 2prong
This power strip is a practical solution for anyone living in an older home that still has two‑prong outlets. Many older houses were built long before grounded wiring became standard, so finding a way to expand your available outlets without rewiring the entire room can be a challenge. This adapter is designed specifically for those situations, and it provides a surprising amount of capability in a compact unit. Before using it, I wanted to be sure it was safe to plug a three‑prong device into a two‑prong outlet. It is legal to use an adapter like this in the United States, but only when you understand its limitations. A two‑to‑three‑prong adapter does not create a true ground. The product page notes that this model is built to UL 1363 standards and includes surge and overload protection, which helps add a layer of safety for older outlets. Still, it is not a substitute for proper grounding, and anyone who wants full protection should eventually have an electrician install grounded outlets. As for the device itself, it is well designed and easy to use. The main body includes 11 outlets, along with 3 USB ports and 3 USB‑C ports for charging phones, tablets, and other small electronics. All USB ports are standard 5V. There is a power switch with a green indicator light, and the back of the unit includes mounting holes if you want to secure it to a wall or desk. The size is compact—about 8 inches long, 4 inches wide, and just over an inch thick—so it fits neatly in tight spaces. Overall, this is a good value for anyone who needs more outlets and charging options in a home with older two‑prong receptacles. It offers convenience, versatility, and thoughtful safety features in one organized unit.
