Nail techs, do your hands, wrists or shoulders hurt after a day at the nail desk?

Have you invested in an e-file to help but instead you've experienced high vibration, skipping and your hands feel even more uncomfortable after a long day and you've lost your confidence?

Many e-files can be bulky and take a lot of space on your nail desk.

Does the noise make your clients feel uncomfortable and bring memories of the dentist?

You want to invest in a better one, but many are out of budget.

Especially when you then have to splash out for education on-top. Look no further!

KB Portable E-File is a revolutionary new must have for any nail tech. Our KB Portable E-File is a powerful yet quiet, minimal vibration e-file with exceptional features like nothing else on the market. With its innovative design, it is USB powered so whatever country you are in, you can plug it into any USB mains plug, power bank, laptop or even your car charger! What's even cooler is that it becomes a power bank itself so you can charge yours or your client's phone, your USB powered desk lamp or your KB Glow right from your e-file.  

A great tool for mobile techs, meaning no extra plugs are required! Not only is this super handy, but it also saves money and energy bills by being USB powered. 

The Portable E-File comes complete with desk stand and bit tidy which ensures you always have your bits close at hand for easy access!  It also has a stop, pause memory function so you can pick up right where you left off.

Wherever you are, there's no need for special charging cables or adapters as this machine only requires a USB port to plug into - perfect for when you lose that charger!

Not only that, but we include free e-file machine education with the purchase of our KB Portable E-File.

Not and E-fail, by any means.

I have been in the industry for over twenty years and had a few efiles in my time, and to be honest I didn’t really need another, I just thought it would be pretty cool to be able to transport it, because let’s face it us nails techs don’t have time in salon to get our claws done, something always comes up and sadly our nails get left and never finished to a standard. So I purely purchased this so I can file my nails on the go 🤷‍♀️

Anyway it’s arrived, the unit itself is slim line and sleek looking with the hand file coming with an extra long length power cord, it did take a long while to charge, but I expected that with it being new. Anyway fast forward a few days when I finally decided to give a try! And wow it is so quiet makes my in salon one sound like a machine gun! I have been using it for a few weeks and have even booted out my older efile and replaced it with this in salon, I am loving the space saving design and the lightweight file, literally zipping over nails effortlessly.

Back fill, infill, full sets, debulking this efile has you covered. I honestly wasn’t expecting much as it’s was a portable device but it really is the dogs ding dongs.

After a full charge I got four full days in salon with it, Aprox 32 sets (both acrylic and gel) by day five it went a little sluggish and the battery power was flashing so had to plug in my old file to finish off the week, but I did want to test the staying power and feel that the battery life is more than capable of coping with soon life, I just need to remember to charge it mid week.

If I had anything negative to say, it would be the fact that the C charging lead is far to small not long enough and it can be a pain charging if you need a boost in between clients, so I did have to purchase a longer charging lead so I can charge it next to my nails stations if needed. So if Katie does a longer charging lead this would be great.

All in all I am impressed as I wasn’t really expecting it to hold up to salon life set after set, but it’s holding its own. I doubt I will be chucking it in my handbag now to file mine on the go! It’s gained its place as a permanent fixture in salon.

So quiet, powerful and gentle! So far the training is amazing and I still have the e classroom training to attend. I am only trained to do soak off and de bulking at the moment and already it has cut down my service time by at least 10mins. I can’t wait until I have completed the training and can get going on cuticles.

Amazing bit of kit!

So quiet I sometimes actually wonder if it’s on! There is minimal to no vibration. The storage box is really handy and I love the fact that the hand piece has a lid. Holds charge for ages too.

Portable E-File

I love this efile - it’s so lightweight & quiet, & is effortless to use.

Amazing 👏

Being in the beauty industry nearly 20 years. I can honestly say this is the best e-file I've even worked with.
