The Zeasun RCR123A Battery Charger comes with 2 rechargeable RCR123A batteries.

The RCR123A battery has a wide compatibly range and can be used for torches, CCTV systems, digital cameras and many more high battery demanding products.

You not only get a convenient battery charger but also the supplied batteries can be charge/discharged around 500 times.

The battery charger also features overcharge, over-discharge, polarity, and short circuit protection.

But are they any good? Do they charge at the correct voltage? Time to test them out!


The Zeasun RCR123A Battery Charger come packaged in a plain Brown cardboard box. The box measures 13.0cm x 7.5cm x 5.0cm and weighs 140G.

Each side of the battery charger acts as an independent charging station and the LED indicator lights will light up to show the different charging stages.  So, you can put a half-charged battery in one side, and a completely flat battery the other and the charger will charge them both fully independently.

The LED light will go from Red to Green when the RCR123A batteries are charged, it will also stop charging them too!

You get two RCR123A batteries that come supplied in a Blue storage box, which has room for an additional 2 batteries too!

Using the Charger.

For this review I’ll also be using the AVHzY CT-2, to see if the stated voltage from the Zeasun manual is indeed correct. To start with you’ll need a 5V DC supply and use any Micro USB cable.  The cable supplied by Zeasun has a length of around 60.0cm, which is a bit short if you ask me! But you can use any Micro USB cable that you probably have lying around.

To start charging you need to insert the Micro USB cable into the input slot on the top area of the charger.  Next, put some power into the charger and insert your RCR123A batteries.  A Red light indicates charging, whilst a Green light indicates either the battery is fully charged or there’s no battery in the slot.

The manual indicates an output of DC4.2V/500mA for each battery.

I’m also going to attempt to power the battery charger using a powerbank!

My readings using the AVHzY CT-2 and charging two RCR123A batteries was DC4.9V/160mA.  When only charging one RCR123A battery my readings were DC4.9V/170mA.

I then decided to ditch the powerbank idea and charge using mains voltage.

My new reading using the AvHzY CT-2 and charging two RCR123A batteries was DC4.7V/140mA. When only charging one RCR123A battery my readings were DC4.9V/150mA.

You can also use the Zeasun battery charger to charge other types of batteries, these include Li-ion/IMR/LiFePO4:14500, 14650, 16500, 16340(RCR123), 16650, 17350, 17500, 17650, 17670, 18350, 18490, 18500,18650, 18700, 20700, 21700, 22500, 22650, 25500, 26500, 26650.

I tested out the reverse polarity protection, and the charger instantly withheld from charging the battery, which is good!

Overall, I quite like the Zeasun RCR123A Battery Charger.  My readings were a little different to what I was expecting but overall the charger will produce the required voltage needed in order to recharge the RCR123A batteries.  I like the independent battery charger aspect and the reverse polarity cut out was instant.

I think the Zeasun charger is very good value for money, if you use CR123A batteries, you’ll know how expensive it can be to replace them.  The other great feature for me is the fact you can use this charger to charge other types of batteries too!

Overall, I highly recommend this charger and RCR123A battery set.
