Selection Criteria
You want a lock that fits your adapter and actually makes it harder to unplug your car, so compatibility and secure fit were top priorities. Build material and durability mattered next, since a lock that cracks or deforms will fail when you need it most.
Ease of use was also important because you should be able to install and remove the lock quickly without tools. Visibility and finish were weighted for users who want to avoid leaving hardware behind or prefer a bright reminder.
Finally, price and pack size helped balance value against features so you can choose the option that suits how often and where you charge.
You want a simple way to keep your car charging when you’re away from it, and this two-pack from LENZ is built for that exact job. It slips over the J1772-to-Tesla adapter after you connect, covering the lever so the plug stays put while your car fills up.
It’s compact enough to stash in the trunk, straightforward to use during quick top-ups, and convenient when you need extra assurance at busy charging hubs. If you charge away from home sometimes and want an inexpensive, low-effort layer of protection, this lock is a practical choice.
What People Say
Customers often praise how easy the lock is to use and how it fits with the common J1772-to-Tesla adapters, noting that it gives a sense of security while charging in public. Many highlight the perceived durability and the convenience of having two pieces.
A recurring caveat is that fit can vary by adapter model, and a few people found it less effective against determined tampering.

FAQ
Will This Fit My Adapter?
Most charger locks are made for the common J1772-to-Tesla adapter, but shapes and flanges vary by maker and year. You should check the product’s compatibility notes and test the fit at home before relying on it at a public charger, since an imperfect fit can reduce effectiveness or interfere with the connection.
How Secure Are These Locks?
These rings and covers are designed to deter casual unplugging and accidental disconnects rather than stop a determined thief. They add a useful physical barrier while you’re away from the car, but you should still lock your vehicle, keep an eye on long charges when possible, and treat the lock as a convenience and theft deterrent rather than full security.
How Do I Use And Maintain One?
After you plug in, slide the lock over the adapter so the release lever is covered and make sure it sits snugly; to remove, unlock the charge port and slide the part off. Keep a spare or two in the car, wipe the lock clean occasionally, and always confirm charging continues after installation to avoid a loose connection.
Wrapping Up
Pick the lock that matches how and where you charge. If you want the most complete solution for mixed use and reliable performance, choose a well-reviewed ONTEN model.
If you charge mostly at public stations and worry about theft or forgetfulness, a bright, visible option like LiangHuLo Red helps you spot and recover your adapter. If budget is your priority, LENZ offers a low-cost two-pack that can still deter casual unplugging.
Before you buy, check that the lock specifically fits your adapter type, test the fit at home, and always remove your adapter when you leave the charger to avoid leaving hardware behind.
