Clamp N Charge: USB Charging Station with Dual USB-A and USB-C Ports
Clamp N Charge is a cord-mounted USB charger that clamps onto any flat (18/2 SPT-1 or SPT-2) lamp or extension cord to add two USB-A ports (5V, 2A total) without using a wall outlet! It installs in under a minute with a Phillips screwdriver and no rewiring required.
Whether the outlet is behind your bed, or the nightstand is in the way; you're charging your phone inconveniently, or not at all. Clamp N Charge fixes that by turning the lamp cord you already have into a charging station, right where you need it. No outlet. No damage to walls. No landlord conversation.

Our journey starts here.
2021
The Inspiration
Outlets are never where you need them. They hide behind beds, sit blocked by sofas, and run out of room the moment two devices need charging. Florida inventor Garrett Puzzo saw the fix already sitting in plain sight: the lamp cord crossing the nightstand. Shortly after, he created and e-filed the patent application for a cord-mounted USB charger that adds charging ports directly on the cord. No new outlet. No rewiring.
2022
The Patent
On November 8, 2022, the U.S. Patent and Trademark Office granted Patent No. 11,495,980 B1 for the cord-mounted USB charging design. Clamp N Charge became a category of one: the only patented device that clips two USB ports onto a flat lamp or extension cord, turning the cord you already own into a charging station.
2023
The Engineering
A patent is a promise. 2023 was about keeping it. Prototype after prototype refined the clamp until it seated perfectly on flat 18/2 ribbon cords, tightened with a single Phillips screw, and confirmed power with a green LED. One rule guided every revision: if installing USB on a lamp cord takes more than a minute, it is not done.
2024
The Product
With the design locked, 2024 turned Clamp N Charge into a finished product: dual USB-A ports, 5V, 2A total output, and a free USB-C adapter in every box. Retail packaging, instruction inserts, and production tooling came together around one promise printed on every box: Power. Simplified. Anywhere.
2025
The Proof
Before it reached a customer’s cord, Clamp N Charge was ETL certified to UL 62368-1 for the U.S. and CSA C22.2 #62368-1 in Canada. FCC Part 15 compliant. Patent protected. Ready to ship.
Every Unit Sold Here Gives Back
For every Clamp N Charge sold on this site, we donate to the Tunnel to Towers Foundation, a nonprofit that builds mortgage-free homes for catastrophically injured veterans, first responders, and the families they leave behind. It's a simple promise: you get power where you need it, and a family who sacrificed everything gets a home. No minimums, no fine print.
Us vs. The Old Way
The old way: crawling behind the nightstand, hunting for an outlet that's always just out of reach.
The Clamp N Charge way: your lamp is already at your bedside so we put the charger exactly where your hand lands.

FAQs
Please visit our Contact page to find out more.
Will Clamp N Charge fit my lamp cord?
Yes, if your cord is flat. It fits flat ribbon-style 18/2 SPT-1/2 lamp and extension cords, the most common type in US homes. Round appliance cords will not work.
Is Clamp N Charge safe?
Yes. ETL certified to UL 62368-1 for the U.S. and CSA C22.2 #62368-1 in Canada. FCC Part 15 compliant.
How do I install it and what tools do I need?
Just a Phillips screwdriver and about a minute. Unplug the cord, seat it in the groove, tighten the included screw, and plug back in. A green light confirms it is working.
How many devices can I charge at once?
Two. The dual USB-A ports share a 5V, 2A total output, and a free USB-C adapter is included for newer phones. It is built for phones, tablets, and earbuds, not laptops.
Can I use it in a dorm or rental?
Absolutely. It never touches your walls or outlets, so there is nothing a landlord could object to. Install it on your lamp cord and take it with you when you move.
