Neat looking piece of kit. Reassuringly heavy feel. That’s the positive out of the way.Three main issues:1. Batteries do not fit securely in the charging bays. Will dislodge if unit is knocked;2. For all it’s bells and whistles, there is nothing to indicate when the battery is charged. On my first attempt (charging the pre-charged Amazon Basics I bought with it) after two hours the unit’s LEDs were flashing and the whole thing was getting hotter and hotter. So. I have for the safety feature to prevent over-charging;3. Instructions are not clear. The instructions are poorly translated. They go in to technical detail without covering the basics (i.e. for those who simply want to charge a AA battery).I would not recommend this product

Very dangerous I would highly recommend you avoid this battery charger, the one I received was clearly very defective as others have testified about this product in reviews, I only tried to charge 4 x AAA Duracell rechargeable batteries it overheats to the point where you cannot pick it up, the batteries got extremely hot to the point of catching fire or exploding and it smells like it’s burning inside,I bought a different manufacturers charger from eBay for under £7 that doesn’t get anywhere near as hot and the batteries are cool to touch and it’s faster at charging AAA and 18500 batteries , please avoid buying this charger if you value you’re life and the life of any family members, you have been warned. This should be pulled from sale immediately amazon. Dangerous beyond words !!!! I was considering sending this charger to trading standards to be tested to be able to get it recalled but I’m returning it to amazon with the hope they read all the negative feedbacks and remove it from sale before someone lose’s their life. I can only hope that they (amazon) really do care about their customer’s safety as this is a death in a box product PLEASE REMOVE IT FROM SALE IMMEDIATELY AMAZON💀💀💀💀💀

A powerful piece of kit whilst being really easy to operate. To begin with you don’t have to stress about leaving the batteries charging overnight, as it automatically stops charging once the batteries are fully changed.Another feature which is impressive and which really does make it value for money, is the ability to recharge batteries that are completely dead having virtually no voltage! This is what sold it for me. I was about to through away a few pairs of 18650 batteries as I couldn’t recharge then due to their Voltage (V) being below the minimum V threshold required to recharge. I came across the Beeway® NEW charger and voila I ended up saving a tiny fortune on having to buy new 18650 batteries.On the other hand, just be careful with the default charger voltage setting, which is set at 4.2V for each of the four charging bays. So if you’re charging 3.7V batteries (especially lithium batteries which become unstable at higher voltages) you have to adjust the V setting on each of the four charging bays accordingly. It does start to gets a tad bit annoying when you keep having to manually adjust each of the bays, one buy one, each time the charger is switched on.Hopefully the next model upgrade will have this, to be honest minor issue, resolved. Apart from that can’t really fault it. All the best!

I bought this charger in order to recharge my Vape batteries, which ordinarily would take a frustrating amount of time to charge via USB.I took the plunge based on the other positive reviews I've seen and I have to agree with them. Charging time is excellent and the light indicator is handy if you need some idea of current charge.The unit itself appears to be great, but doesn't feel particularly sturdy; as it's very lightweight. I'd recommended taking time when both adding and removing the batteries, as the metal contacts do feel a little unstable when sliding the battery into place. Very good otherwise.

I really like this battery charger. I bought it, and use it mainly for re- charging up torch/flashlight batteries and have found it very easy to use with the green lights coming onto indicate at what stage the charge is at and then all three of them being lit up whenthe charge is complete.It comes with an Instruction Manual which is rather verbose, but it does at least givea user the necessary details for operation. I found it useful.

This is a very versatile charger and with manual current adjustment can cope with almost all cell type rechargeables. I have the rare 3.7v type. The charger is set to auto charge at the most common voltage so the fact that you can manually reset is appreciated and not too difficult to do. Would have a 5 star rating for ease only if the required charge was detected automatically, which is a lot to ask. Came with a UK plug. Once again with Chinese devices, the instructions are tiny. Why so small? They really need to get their act together as we are not all equipped with a natural zoom lens in our eyes. Thank God for the mag function on our phones.

This charger is clumsy, due to poor design of the terminal contacts, and the instructions are a bit weird, and there was no carry bag included - this part of the item description was probably copied from the i2 page. The price is pretty good though, and I managed to validate the charger as genuine on the official nitecore site, so I was happy to stick with it.However, on the 5th use, battery slots 1 and 3 suddenly stopped working. Shortly thereafter, slots 2 and 4 also went dark. I've tried using both mains AC power, and 12V DC, with no change in behaviour. It's too late to return the item, although the 12 month manufacturer warranty should allow me to get a replacement if I can be bothered.

Gets very hot. As you can see, arrived today plugged it in. The back of this is >50°c with the hottest being 70°c! Not going to leave this unsupervised, also cNt imagine that heat will do the casing any good in the long term. Will update if things change.
