EHPRO Lock RDA Intro

Ehpro is a long established (2011) Chinese brand, and the Ehpro Lock RDA follows a great range of products that include the Bachelor X RTA which scored highly in our full review. Ehpro has also produced Mods like the Fusion 200w TC Box and RDA’s like the Panther and the Nixon V2.

What Is it?

The Ehpro Lock is a 24mm single coil RDA with a nut-style top cap and honeycomb 810 drip tip. The Lock has a side airflow system directly onto a notch coil which allows for build-free replacement and a squonk pin for squonk lovers.

Ehpro claim there are only 3 simple steps to build a coil:

  1. Take the top cap off;
  2. Push the coil into the deck;
  3. Heat the coil to make it heat evenly. Install the cotton.

The Lock RDA is also compatible with conventional coils and comes in three colors, Black, Stainless Steel, and Blue.


Who is it for?

The Lock RDA is for flavor addicts and RDA beginners. This RDA will give an easy building experience.

Our Vibe

When it comes to design sometimes, the best looking tanks have one inherent design flaw, too smooth and shiny to get a grip. You then have to play the stuck jar lid game to take the top off and replace the coil. Should I try to use brute force, use a dish towel or run it under some hot water?

The Ehpro designers have suffered from the same and rather than taking a sledgehammer to crack a nut. They just used a nut and a little industrial design to solve the problem.

Add to this the simplicity of dropping the pre-built notch coil or even regular coil into place, and you’re as sweet as a nut.
