Ehpro 101 Pro 75W TC Mod Review

Ehpro 101 Pro 75W TC Mod

Here’s a look at a recent release from EHPro out of Shenzen. If you’re not familiar with them they are a manufacturing company from China who has been making some excellent vape gear for quite some time now. They produce some really amazing products like the Billow and Bachelor series of RTAs. They were also the ones behind the Nixon a fairly popular RDA when it launched. This latest release is actually an update to a previous device of theirs the Mod 101 and it comes with a number of small but meaningful improvements. Here are my honest thoughts on the EHPro 101 Pro 75W TC Mod.

Inside the kit you will find the Mod 101 Pro, a 25-22mm beauty ring, a warranty card, warning card and a manual for the mod. Both the packaging and contents are pretty basic but this is the mod only kit and it includes everything you would need to use it save a battery and an atomizer. Everything arrived safe so no real complaints there.

The Ehpro 101 Pro Mod:

EHPro refers to the Mod 101 Pro as a pen-style device but really it’s more like a tube or mechanical style mod that’s regulated with a number of built-in protections.

It’s made of stainless steel and is available in a variety of colours like SS, Black, Blue and Rainbow. It supports the three major types of vaping cells including 18650, 20700 and 21700 which results in it being just a bit taller than the average mech mod on account of the button and controller board inside it.

It stands at 117.5mm without an atomizer attached and is almost more of a baton mod then a pen mod. Unlike the original Mod 101 it does not support smaller 18350 batteries or even 20350 batteries like you might expect with its upgraded size so it’s a solid tube and not made up of threaded sections like the original.

To insert a battery you unscrew the bottom cap which is clearly marked negative. It fits 20700 and 21700 batteries natively and despite not having any kind of adapter for the 20700s there isn’t any battery rattle once it’s closed up.

In order to use an 18650 with the device it comes with an 18650 adapter which will ensure there is no rattle when using the smaller sized cells. The threads on the battery cap and are nice and smooth and it has two little holes drilled through it for venting should anything go wrong with your battery.

At the top of the device it’s got a stainless steel threaded 510 connection. The threads on the 510 are also nice and smooth and it has a gold plated spring loaded center pin with plenty of travel so pretty much anything should sit flush on it.

The diameter of the device is 25mm so anything beyond that will likely have some overhang but the kit comes with a 25 to 22mm beauty ring so you can use your smaller 22mm diameter gear with it and it will still look pretty clean. Just down from the top on the one side is the 0.69” OLED screen. It’s incredibly simple but well laid out for a tiny screen and a slight upgrade from its 0.49” predecessor.

There’s a battery bar on the left to indicate remaining battery, to the right of the battery bar it shows the resistance of the attached atomizer and the voltage it will fire at and on the right it displays the current wattage.

If in TC mode it shows the battery bar left, resistance, watts, temp, TC mode and Celsius or Fahrenheit. On the side opposite the screen is the fire button which is actually the only button on the device, no adjustment buttons on this thing.

I actually had the original Mod 101 and it was notorious for having some serious button rattle and I’m happy to say with the 101 Pro there is absolutely zero rattle from anywhere on the device.

There isn’t a USB port on it so no updates and no onboard charging. It’s a super simple device and so far rock solid so updates aren’t really needed but no onboard charging can be a bit of an issue if you’re out and about and need to top up.

Near the bottom of the device it has a bit of fairly subtle laser engraved branding with EHPro on one side and Mod101 Pro on the other. The overall look is clean and it’s basically a tube with a small screen and a button.

Usage and Performance of Ehpro 101 Pro:

To use the device you first turn it on with five clicks of the fire button. To enter the menu you click the fire button three times. To navigate the menu you repeatedly click the fire button and to make a selection you just wait about 2-3 seconds.

It increments in steps of .5 but will scroll through pretty quickly if you hold the button down. If you’re making an incremental adjustment and need to reverse the direction it’s scrolling you click the button quickly two times and it will start decrementing. It’s pretty counterintuitive and even a bit confusing at first but once you try it out it’s an extremely simple way to navigate a menu using only one button.

The device includes options for VW(variable wattage), Bypass, TCR, TC Ni, TC SS and TC Ti. When you enter the menu you will see options for Power or Temp/TC Max Power Set, Work Mode, Calibr Int, DisMode and Exit Menu. It will show Power or Temp/TC Max Power Set based on the current mode it’s in which you set in the Work Mode sub-menu, the Calibr Int sub-menu lets you set the resistance but it also asks when first attaching an atomizer. DisMode lets you change the orientation of the screen and Exit Menu just exits the menu.

It takes a bit of getting used to but the more you use it the easier it gets to navigate the menu using only one button. Really it’s pretty smart how they implemented it and having just a single button and a single little screen makes for a very clean look.

I found it worked just as well as the original but now it can hit 75w instead of just 50w and they also addressed pretty much all of the major issues I had with the first one. As I mentioned no more button rattle and they also got rid of the annoying auto-shut off that you couldn’t disable.

Basically every time you left it sitting for a few minutes it would power itself off requiring five clicks to turn it on before you could use it. With the Pro it just goes in to a sleep mode and wakes up with a single click. Temp control works well on it and it includes TCR if the default settings don’t suit your needs. Power appears accurate and battery life seems good even sitting idle. As simple as it might appear it just works and it’s been working well for as long as I’ve been using it and the original.

Final Thoughts on the Ehpro 101 Pro Mod:

I was a fan of the original Mod 101 even despite its minor short comings so it’s only logical that I’d also enjoy the Mod 101 Pro which I definitely did. While I do find it to be a bit bulky as a regular mech mod user I appreciate its form factor and the addition of regulated power and protections.

I think this thing would be ideal for those looking for a tube style device but are still on the fence about going fully unregulated with a traditional mech mod. Not only does Ehpro 101 Pro Mod look slick it performs like a champ and having those extra added features and protections will only make it that much more appealing to those looking for something in this style.
