SPD A8 – The New Updated TC Mod From Ehpro

The Ehpro SPD A8 is the follow up to the Ehpro SPD A5, which was the first temperature controlled vape mod from Ehpro, also featuring up to 50w of output power, small form factor and powered by a removable 18650 battery. Ehpro SPD A8 Review

The Ehpro SPD A8 has been totally redesigned and bears very little resemblance to its predecessor, it now sports a rugged look with juice resistant housing, centrally located 510 connector, an output power upgrade to 80w and a built in 4000 mAh lipo battery recharged via micro USB.

The SPD A8 will be released in conjunction with the Billow V2 Nano, and sold together as part of the Ehpro EKit G3. Lets have a look at what the A8 brings to the table!

What’s In The Box?

  • Ehpro SPD A8
  • Micro USB cable for charging and future software updates
  • Instruction manual

As mentioned, the A8 will be available together with the Billow V2 Nano RTA as part of the Ehpro EKit G3, above is what you would expect to find if you purchase the SPD A8 separately. I must mention that my unit was a test sample received for the purposes of review, so the contents may change for the final retail version.

Ehpro SPD A8 Battery/Body/Build

I must say that upon first look I expected the Ehpro SPD A8 to be a pretty weighty unit, it’s pretty big and looks robust and solid on first appearance. However, the unit itself is surprisingly light in the hand, it weighs a lot less than I expected it to!

The finish has a rugged appearance, my review unit was black but it will be available in a range of different colors.Ehpro Ekits G3 kit review

Unfortunately it did feel quite cheap in my hand with very clicky buttons which I felt let down the overall appearance of what I thought was a solid looking mod! The housing itself is designed to be juice resistant which will prevent juice from leaking into the internals and rendering the unit unusable.

An OLED screen is present which is clear and concise, it gives you information on the current battery status, power output, resistance, temperature limit (if in temperature control) and the current mode The menu system took a bit of getting used to at first but the more I used the unit the more I got used to it. It isn’t particularly user friendly at first!

It’s 5 clicks of the power button to turn the unit on, but you have to do this pretty rapidly as those 5 clicks must be completed inside 2 seconds otherwise you have to start again. By default, the device is in temperature control mode when you first turn it on.Ehpro SPD A8 Screen

Pressing power and + or power and – will take you into the menu screen, + will scroll through the different menu options and – will return you to the previous menu. Selecting a menu option is done by pressing the power button on the highlighted option.

There are 6 options present in the menu system and the first is Working Mode Setting (which means you change your setting from Temperature Mode to Power Mode for wattage or Voltage Mode for voltage).

The Ehpro SPD A8 at present only supports Nickel wire for temperature control. The next menu option is Temperature Units Switch which gives you the ability to switch between Celsius and Fahrenheit, next is ‘Hands Mode Setting’ which will switch the screen orientation, after this is ‘Display Mode Setting’ which enables you to turn off the screen to save power, the next setting is ‘TC Power Limit Setting’ which enables you to set a wattage output limit when in temperature control, and finally you have ‘System Software Updating’ which you will need to use when updating the software whilst plugged into a computer via the micro USB cable.

The 510 connector is spring loaded so that you can get a flush fit with your atomizers. There was a ‘caution, hot surface’ warning at either side of the 510 connector, which I didn’t feel was necessary. The unit never seemed to get particularly hot during use even when running it for a period of time at the 80w maximum.threading on spd a8 tc mod

The SPD A8 is powered by a built it 4000 mAh lipo battery, which is charged via a micro USB port at the side of the unit. Interestingly, the mod also supports future software updates via the micro USB port, however Ehpro are remaining tight lipped on what they have planned for future upgrades.

Temperature Control

Temperature control is easy to set up and start using with the Ehpro SPD A8. The unit is set to temperature control by default out of the box, or if you have changed the setting to power or voltage you just go back into the system and change it back.

You will need an atomizer with a nickel build to take advantage of the temperature control function, as for now the SPD A8 only has support for Nickel builds with a resistance down to 0.1ohm.

You will be prompted as to whether the coil is new or existing, you select either option by pressing + or -. This will take the resistance of the coil and you are then ready to use the temperature control mode on the Ehpro SPD A8!

You can limit the temperature up to 600F, I have found that setting it to 440F (my preferred setting for temperature control) is ideal, and performs just as well as any other temperature control mod.

How Does The Ehpro SPD A8 Perform?

Battery lifespan is superb with the Ehpro SPD A8 thanks to the built in 4000 mah battery, plus charging on the move is quick and easy with the micro USB charger. It has lasted me days in between charges, so it’s an ideal mod for me to take out and about without needing to worry about whether the battery is going to last or not.

It does seem to charge up pretty quickly too, only needing a couple of hours to recharge fully. You can also vape whilst charging as the SPD A8 does support pass-through capability.Billow V2 on the Ehpro SPD8

The 80w maximum output power is excellent and means I can get great performance out of any of my sub ohm mods. 80w is more than enough for most people’s usage! Of course using the device at higher power ranges does drain the battery considerably quickly.

In temperature control mode, I do seem to get a longer battery life than using it in standard power or voltage modes.

Overall, the Ehpro SPD A8 is a superb little performer!

Final Review Verdict

Despite the quite cheap feel of the Ehpro SPD A8, it’s actually a very solidly built little unit, I’ve had no problems with any of the parts and the 510 connector has fitted all atomisers I’ve used with it perfectly. The Billow V2 Nano in particular looks great and the Ehpro EKit G3 containing both of these is going to be a great little buy.

It’s a great little performer, and powerful with 80w of power, the temperature control function works really well and the battery life is great with the built in 4000 mAh battery.

The only thing I would like to see is support for Titanium wire in temperature control added in through a future software update if that is at all possible, as Titanium wire is one growing in popularity by the day, but it still functions very well in temperature control mode.

For those looking for a solid little unit with great performance, the Ehpro SPD A8 is ideal.

Build Quality
Ease of Use
Been vaping full time for three and a half years, started on cigalikes for a fair while then curiosity got the better of me and I moved onto an ego/ce5 set up after, a month or two later I was seeing people walking around with these interesting shiny tubes and I thought 'I gotta get one of those'. Before I knew it a trip down to my local B&M got me my first VW mod, an Innokin SVD, paired with an iClear 30, and I was hooked. Soon after that I was jumping to VW mods both box and tube shaped, before I then made the jump to rebuilding and thus sub ohming, with my first RDA and mech mod. These days I'm still preferring mechanical mods, but using VW mods with both RDA's and tanks alike whilst on the move, most importantly I am still loving vaping!


  1. first time vaping , i got your SPDa8 mod , went to use it and there was the red light flashing at the bottom of the unit. nothing comes up on the little screen , i cant even use this mod box . Now im wondering if i made the right choice in mod boxes. I got it and cant use it so i dont know how it performs , i know i’m not well educated in vaping but friends and family are and they say its not gonna work properly. So frustrated that i cant vape with it , some people say thats why they never bought one is because of the problems. I still convinced its a good product i could only wish that the company can make this right and send either a new one or even a good used working one, mind you im a newbie but i’m not convinced that the product or the company are all bad i just want a good working mod so i can start vaping.

  2. yeah updated firmware gives you temp control on titanium wire, disables passthru and ups your mod form 80 to 120watt

    battery life at 22to35 watts all day
    temp mode , for me i like running kanthal a1 in temp mode at 220. i get better flavor than wattage mode at 22 26watts.

  3. What is your firmware dated to? The Firmware of my SPD A8 is from August 26th and supports Titanium, but prevents passthrough.
