New version!!! May 2025
The best and most effective way to ground laptop or notebook computers! The innovative pass-through USB 2.0 and 3.0 compatible adapter by ElectraHealth.com allows you to ground otherwise ungrounded devices without a mess and without losing a USB port! Male USB-C (also comes with adapter for to use as a male USB A) port on one end goes into your computer - electrical plug connects to a properly grounded outlet - and on the other end of the adapter is a female USB 3.2 port that you can plug any USB device you want into. Don't sacrifice a port for grounding!
Laptops, also called notebook computers, use switch-mode power supplies. These power supplies are the "charger" for the unit. It is healthiest to use a battery-operated device like a laptop or notebook or pad on battery only. However, in the real world most people use it plugged-in to the charger. Using the battery over and over again also decreases battery life over time.

The problem is that switch-mode power supply when plugged-in to your device is generating high frequency voltage spikes. Your body is put into the path of these spikes. By grounding your laptop or other device with this USB Grounding Adapter, a safer and better path is given for these high frequencies to travel.
We have conducted tests that show a significant drop in human exposure to electrical current when a laptop is properly grounded vs. an ungrounded laptop, when the laptop is plugged-in to the charger. This is a large concern, and so we have created both the USB Grounding Adapter and the Ethernet Grounding Adapter.
Desktop computers with a 3-prong plug and metal body do not need to use this adapter. Laptops and other 2-prong plug devices should use this adapter. If your laptop is plugged-into a USB printer that has a 3-prong power cord, then you would only need to use this adapter when your laptop is not plugged into that printer, since the printer would be providing ground. Many printers are only 2 - prong, in which case use this adapter. Likewise if your laptop is plugged into a monitor (screen) that has a 3-prong plug, you would not need to use this adapter at that time. But it is recommended to have one at all times when traveling.
Simply plug this adapter into your laptop and plug the electrical plug into a properly-grounded outlet and your laptop is instantly grounded. PC and Mac supported, the highest quality components used on this premium cable, supports USB 3.2 SuperSpeed
