Great looking battery, Molicels perform slightly better (08 August 2023)

I have purchased this for my Drag X Pro. Excellent performance ended up getting a Molicel 21700 which seemed to last around 10% longer. Both perform really well. This looks a lot better with the branding for those who have the battery visible.

I recommend using a dedicated charger, using the Vape to charge the battery does not charge it fully.


GREAT BATTERY (29 June 2023)

This battery is great value, I ordered one as a backup in case my existing battery runs dry but I tend to use this battery 90% of the time as my main battery.

It takes a while to charge but this isn't a problem for me.

HOHM RUN XL 21700 BATTERY (4000MAH 30A) (21 May 2023)

Works perfectly getting some good amount of time out of it when vaping this will be my go to for 21700's

Awful fit (11 May 2023)

I have been given a FreeMax mod as a birthday present and needed some 21700 batteries. I decided upon these as the reviews looked good. Unfortunately once I went to use them it was obvious that they were such a tight fit it would be very for me to remove with my arthritic fingers. My son then tried (successfully in the end) and he agreed that they were too snug fitting.

Great batteries (14 April 2023)

With batteries, you tend to get what you pay for, and although there are less expensive batteries out there, you really do tend to get what you pay for... these have a large capacity and a great build quality.

By Moanyvaper from Hertfordshire

Decent battery (08 April 2023)

Decent enough battery, not as good as i was expecting though, last about 7 hours of regular vaping, around 150 puffs at 3/4 second a puff, at 65watts 0.17ohm, the reviews that say it lasts a day or day and a half must sleep all day, not a chance! Last longer than any battery I’ve had before though! I’ll be buying another 100%

Brilliant batteries (25 March 2023)

These are my first 21700's for my new L200 Classic and wasn't expecting much as I have always used 18650's but wow these really make a difference they last waaaay longer and i don't think I could go back to 18650s now! Good quality batteries by a trusted brand at a great price by a fantastic business! Cheers VapeClub!

Huge capacity (09 January 2023)

Wanted a battery with as large capacity as possible and this didn't dissapoint. Drains alot slower than my Aspire zelos 3 with built in 3200mah battery. Very happy.

By Jam from Bristol

Great life span (16 September 2022)

Charge once a day and lasts me all day with about 20% left at end of day vaping at 80-90 watts. Charges very quick when I do.

By Zakydeamas96 from Grimsby

Amazing (06 July 2022)

I have been using this for a while now and it does not disapoint, lasts me a good two days running on 40 - 60W. Great high capacity battery.

Great Battery (09 June 2022)

Noticeable upgrade from an 18650 in my nunchaku 2, I don’t feel like I’m swapping batteries as often and easily lasts the whole day with some change

By Zakydeamas96 from Grimsby

Top Quality (08 June 2022)

This battery is by far the best one I have used, it drains very slowly and charges very fast, Highly recomend

By Joe from Bramford

The best (19 April 2022)

These are by far my favourite 21700 batteries they seem to hold there power very well I don’t have to worry about battery life if I am out all day and have one of these in my drag x pro

By Disco from Ross-on-Wye

Great battery (07 March 2022)

Bought one of these for my Voopoo DragX Pro… Great power, long charge, lasts all day & night at 50w whilst I’m chain vaping & chucking out big clouds. For best results, charge in a dedicated charger @0.5 amps… through your device is ok but batteries like a bit of TLC, so a low & slow charge and they’ll look after you

By Theadsi from Leek

Brill battery (18 December 2021)

Had the drag x pro mod was fed up of 17650 running out all the time 3 or 4 times a day so opted to by this battery best decision I made last all day at my usual use level can rate it better

By Alil from London

Really powerful batteries (11 December 2021)

Really powerful batteries! Lasting like 2 days if you smoke MTL on your device or even more depends on your taste.
They came extremely well protected and packaged and battery silicone cover.

By Rubz from Iow

Unsure (12 September 2021)

So, I’ve ordered four I think of these ones, the battery’s are great and everything however I’m not sure if it’s the battery build, my vape or just a general problem with having a larger surface area to damage with the bigger battery’s but one drop of the vape and the battery top dents in making it unusable. It does look like a flimsy bit of metal compared to another I have.. Anyway I have ordered the other battery’s available on vape club so I guess you’ll see a comparison review from me on those ones soon.

By Deany from West Midlands
