The Hohm School 4A battery charger by Hohmtech will allow you to charge up to four vape batteries at the same time. It is always recommended that you use an external charger for vape batteries, not only do they charge quicker they also make your batteries last longer. The 4A charging current allows for four batteries to be charged at 1A or two batteries to be charged at 2A for a faster recharge. The autonomous charge feature will automatically detect the battery model and the number of batteries and will pick an appropriate charge current.

  • Quad Battery Charging
  • Built-In Safety Features
  • Power Regulator

Compatible with popular battery models, the Hohm School charger can be used with 18650, 20700, 21700 and 26650 batteries.

Multiple inbuilt safety protections feature in the Hohm School, such as reverse polarity protection, short circuit protection, and overcharge protection.

Charges up a treat (20 July 2023)

When I first got this it took forever to charge up my battery's I use 21700s for my snowwolf mini mod. But I realised that my old charger wasn't charging the battery's up fully , so this charger was doing the job properly and after the first 2 times, it charges quickly and properly. Which means I rarely have to use more than one battery a day even if I'm hitting my vape hard that day!

Better than the more expensive brands (25 March 2023)

This charger is amazing! Doesn't look like much but the quick charge is insanely fast and its USB so you can plug it in pretty much anywhere ( even works from my Xbox )

Solid Nitecore competitor, picky on power source (05 November 2022)

Having used Nitecore chargers for years, I naturally wanted a similar product to replace my failing chargers. This charger seemed like a good choice, and to some extent it is, even if it is only because CV doesn't offer anything better.
While Hohm's device basically does its job well, I would have preferred more information on what power sources it will accept. I can, for example, confirm that it will not work with a current Macbook Pro (using a USB-C to USB-C lead). Maybe a bundle with a 6ft usb cord and a charger would be a good idea here as not everyone will keep a drawer of old electronics like I do.
Compared to Nitecore, I also miss the more than binary indicator lights. Hohm has no way of telling you how far along it's charged your batteries.
In spite of all this, Hohm seem to value build quality more than Nitecore, so I shall be sticking with it regardless.

Battery charger (17 September 2022)

Brilliant for a budget battery charger, turbo charge is brilliant and love how I can plug it to a usb slot and does not require a plug!

Beats the big brands (13 February 2022)

I can honestly say after years of owning a range of big brand chargers, this beats them all hands down, and some more!!!

By Jack

Good (22 January 2022)

I bought this as my first battery charger, it' a really good one, very simple to use and very compatible! I have only so far been using the 2 'fast charging' ports and am very satisfied!

By Frankee J from Hertfordshire

Perfect for use (22 January 2022)

Works well for use. The different lights are great for letting you know their charging status. Only thing I’d change would be to make the lead a little longer, however can use lead to charge both my vape itself and the battery charger.

Good price but a few issues (04 September 2021)

Overall for the price this is a quality charger and can’t really complain. It’s very small and compact, well made and feels sturdy, not cheap and nasty like some.
I do have a few issues which may not bother the majority of users.
Firstly the cable is very short which makes it difficult to find a safe place to charge. I had to use an extension cable, but keep in mind that’s just my home set up. You will also need to buy a separate wall plug for the cable.
My main issue is the LED charging display. It’s so tiny I had to actually lean right over and close to the charger to see it!
Now if you’re colour blind like myself the tiny red light when charging will turn to green when charged, so for me personally I had to get someone else to keep an eye on it!
Much prefer a visual display like my old Nitecore where you don’t have to rely on colours. Worth keeping in mind if you are colour blind!
I actually didn’t find the 2amp charging to be much quicker than the 1.5amp on my old Nitecore so mixed feelings about this one.
I’m sure it’s perfect for the majority of you though and for the price you can’t go wrong!

Quality charging device (09 May 2021)

Bought this with two hohm run 21700s and I have to say I’m extremely satisfied.
It’s solid and looks great, the two slots on the inside are slimmer and better suited for 18650s.

Overall 10/10 and my only gripe is that it can be difficult to push the spring connectors past the click point that it uses for detecting larger cells.

By Jay from Leicester
