Nitecore Digicharger D4 Review

Finding the perfect digital charger for your batteries can be daunting – especially if you own several different vaping devices and need to charge different batteries for all of them.

Thankfully, however, Nitecore has recently come to the rescue with a new line of chargers, which they call the ‘Digicharger’ line of products. These chargers are full-featured, and contain a ton of smart processing power that makes charging different batteries a no-brainer.

Today, we’ll be taking a look at the D4, which is essentially a 4-port smart charger that will accept a wide variety of different types of rechargeable batteries.

But is it worth the money, and does it perform up to par with comparably priced products?

About the charger

We’ve reviewed a few other Nitecore chargers in the past – and we really liked them, which is part of the reason for why we were pumped to give this bad-boy a try. The main difference between the Digicharger and the Intellicharger (which is the type that we reviewed before, also made by Nitecore) seems to be that the Digicharger actually has an LCD screen, while the Intellicharger just had lights and indicators – so that’s a pretty cool feature that we noticed coming out of the gate.

As far as first impressions go, the packaging seemed really nice. The box it came in was quite large – but that’s to be expected, since the charger itself is actually pretty big.

Like the I4, the D4 comes with a mains plug-in cord. There is also an instruction book – which seems quite informative.

We must say that the charger itself really looked good right out of the box. As far as inputs go, there is a mains input that you can use to plug the device into mains power, but also a 12V DC input that you can use to charge it in a car – which would be really nice if you were driving or out camping or something like that.

Note: If you want to charge this device in your car, you’ll need to buy the right cord and adapter, as the charger itself doesn’t come with either.

The LCD screen is actually a lot bigger than we thought it would be, which is nice. There are also 4 battery slots with sliding connectors, which helps for charging batteries that are different sizes.


  • Contains an integrated microprocessor that automatically identifies the types of batteries plugged into it
  • Selects the appropriate settings based on the detected battery
  • Features 3 charging modes… CC mode, CV mode, and –dV/dt mode
  • Optimally designed for NI-MH/NI-CD batteries
  • Helps to extend battery life by monitoring voltage and keeping it within safe limits during the entire charging process
  • The settings are easy to access and change
  • Protects small-capacity batteries (such as AAs and 10440s) from overheating
  • Equipped with a highly visible and intuitive liquid crystal display
  • The display can be turned off for charging at night – so the lights won’t disturb your quality of sleep
  • Made from high-quality, ABS fire retardant materials and constructed to the highest possible safety standards
  • Can operate on either 100-240VAC mains power around the home, or 12VDC in vehicles – making it suitable for use in almost any circumstance

Build Quality

As far as the build quality is concerned, the device was pretty big – but not too weighty. It is made of plastic – but the plastic is ABS fire resistance plastic, which makes it safer and less likely to catch fire if something were to go wrong. It also has rubber feet on the bottom, which give it a better grip on slippery surfaces.

Nitecore Digicharger D4

As far as we were concerned, the build quality was top notch – so high marks to Nitecore in this category.


As far as compatibility is concerned, the D4 will handle a wide variety of different types of batteries. In the IMR/Li-ion/LiFePO4 category, it’ll hold and charge the rechargeable versions of all of the following…

26650, 22650, 18650, 18490, 18350, 17670, 17500, 16340(RCR123), 14500, 10440

In the Ni-MH/Ni-Cd category, it’ll hold the following…

  • AA
  • AAA
  • AAAA
  • C

Of course, you should always keep in mind that you should never put a regular battery on a charger. This device was only designed to recharge batteries that were built to be rechargeable.

What did we think of this charger?

We were very impressed with how easy it was to keep track of different batteries plugged into the charger. The LED display really adds a lot of visibility to the process; more than you might expect it would. We really liked the I4 Intellicharger, which was also built by Nitecore – but this device was almost easier to use because the display made it incredibly easy to view exactly what was going on, and we really liked that.

Personally, we really found the entire design quite clever. The charger keeps track of almost everything – arguably more than you may ever need to know in terms of information. It even gives you a charge finish time (after the batteries have been charging for a while) which is really nice. There is also a smaller version of this charger – the Digicharger D2 – and it’s almost the same, except that it only has two slots, not four.

If you don’t need 4 entire slots, then you might want to consider going for the D2, as it’s a bit cheaper – but really, the D4 is an amazing device. It’s a plug in and go system, it’s reasonably priced, and it’ll certainly keep your batteries charged without a problem!

Two thumbs up to Nitecore for the D4!


One of the best things about this charger is that it’s compatible with a huge range of different types of batteries. But what makes this even better is the fact that you can charge several different types of batteries with it at the same time, because each battery slot is independent. Each slot will (on its own) detect what type of battery is in the slot, adjust the power levels to be what they’re supposed to be, and charge the battery until it’s done – at which point it will cease charging to prevent overcharging, thus prolonging the battery’s lifespan.

Additional Features

Once you start it up, the screen will basically be blank, and it will say “D4” on the display. You will also see 4 battery status indicators, but with no battery installed, they won’t show anything. We plugged in an 18650, and basically instantly, the charger responded. Calibration seems to happen right away. Before we had even done anything at all, the charger was already charging the battery at the optimum voltage, and showed us that our battery had only 1 bar of power out of 5 – which seemed quite accurate.

The actual battery type is also displayed brilliantly on the screen. It also shows what type of charge mode has been selected by the device. A button on the side will also allow you to access the charge information on each individual slot, which is pretty cool.


All in all, this charger is very intuitive, and offers a super-basic experience for people who need to charge several different types of batteries. Keeping track of all kinds of different types of chargers for individual types of batteries can be incredibly time-consuming and frustrating – so the fact that Nitecore has put out a charger like this, that also offers a ton of information on the display, is simply phenomenal.


The only drawback that we could really see with this product in-particular was that it might have been overkill for our simple vaping needs. With that being said, having an extra slot or two could never hurt anything – so really, in the grand scheme of things, we couldn’t find much of a downside for this product.

It would have been nice to get a DC cable and adapter with it – but for the price, we can’t complain that it didn’t come with these.
