The reality of this device is not quite as nice as you might image from the title, but the Jerk Stopper could save you a lot of money and trouble. The Jerk Stopper is a simple solution for a problem that should not even exist.
The goal of the Jerk Stopper is to limit the damage to power plugs in notebook computers. I have seen many notebook computers with power plug damage due to someone tripping over a power cord and ripping the outlet from the computer. Most of the time the damage is extensive because manufacturers generally directly solder the plug to the computer main board.
The installation of device is simple. You thread the power cable through the U-shaped groove and snap the two pieces together. You then install the device into an available USB or RJ-45 jack. The premise is that the RJ-45 or USB jack are much stronger than the power inlet. The cost for this device is low at just $9.95.
It is not right that it should not be necessary to purchase an extra device to protect your notebook computer. Some manufacturers have taken the step to create right-angle power plugs which offers a big more protection than straight-in connectors. More needs to be done by notebook computer builders to provide better connectors and strain-relief designs. Until they do it there is the Jerk Stopper.
By the way, one manufacturer has created a solution with mixed review. Some Apple notebook computers have a magnetic connector that simply pops away when the cord is tugged. There are complaints that the cord falls off of the computer, but it is better than the alternative.
