The Nitecore Intellicharger I2 version battery charger is a simple to use, no fuss charger from Nitecore which is ideal for use with the type of IMR / Li-Ion batteries which power many popular brands of vape equipment.  This is a consumer review – I actually have one of these.

After buying a Kangertech Subox Nano, which has a built in battery charger, I quickly realised what a pain this was as there is no way I can deplete a battery whilst also recharging it – in other words – I can’t live my life and do my work connected to a mains powered charger all the time!  So the first thing I did was go out and buy a spare Efest IMR 18650 3.7v 3500 mAh battery thinking that I could charge it during the night in the nano.  It didn’t take long to find out that this was completely impractical as well – I really needed to find a charger which could charge the battery whenever I wanted to.

Having done my research I decided to purchase the Nitecore Intellicharger I2.  The box states that it is compatible with the following types of batteries.

IMR / Li-Ion – 26650, 22650, 18650, 18490, 18350, 17670, 14500, 10440, 16340 (RCR123)

Ni-MH / Ni-Cd – AA, AAA, AAAA, C

The latter were a bonus for me – because I am constantly recharging batteries of the AA type and having another charger which can handle those is handy to say the least.  The packaging also states “Fire Retardant Materials”, “Intelligent Circuits” and “Worldwide Insurance”.  The first two of these are of particular interest, as it is a well known fact that over charging Lithium Ion batteries can cause overheating and a fire if they are not handled correctly.

Using the Nitecore Intellicharger I2 Charger.

The charger has a separate cable which connects to the box itself on one end and the other plugs into the mains power supply. (UK Standard 240v in my case).  The plus and minus polarities are faintly embossed on the compartments for the batteries (could be a little clearer) so that you do not insert them the wrong way round although it does say on the box that reverse polarity protection is incorporated.
One single battery can be charged or two batteries can be charged simultaneously and are monitored independently.  They are inserted into their slot by pushing on a spring loaded connector – this is quite ingenuous because it allows the intellicharger to cater for different sizes (physically) without the need for lots of different slots.

Once in place, simply apply the power and the I2 charger will go through a couple of tests before charging begins.  The unit comes complete with fitted LED’s which display the progress of the charge – which in the case of a flat IMR 18650 3.7v 3500mAh battery takes between 5 and 6 hours – so quite a long time for those if they are the ones you use, but by no means a problem so long as you keep on top of your cycle.  Once at full capacity, the intellicharger shows three lit lights and stops adding charge to prevent damage and overcharging.

One interesting little point – and whether this applies to all the units I am not certain – but when it is charging, and in particular when it is first plugged in and starting the process, it makes a very quiet beeping noise.  For this reason I kept my eye on it (and still do to some extent) but it hasn’t appeared to be a problem sofar.  Maybe you could comment below if you have one and let me know if yours does the same?

(As derived from the outer packaging).

The unit also comes complete with a plethora of certifications, something you don’t always get but is always worth watching out for including CE FC and RoHS markings.

If you want to use this in a car, there is a socket which accepts an adapter lead from a lighter port on the car – however this was not shipped as default in the case of my purchase and I presume is available as an add-on from the supplier.

When doing a review such as this, its quite easy to run out of things to say – so in summary I would pass on that I am more than pleased with this, it has enabled me to confidently and safely charge my spare and is performing exactly to my expectations.  The price is more than reasonable, coming in at around the £15 mark depending on where you buy it from.

Would recommend!
