I just got this charger and it seems to work really well. But it gets really, really warm. Is that normal?

Not sure if it's normal but mine does too as it's charging. It's great,though, and charges my phone very quickly.

Yes. mine does too. I have had mine for several years and it still works as good as the first day I got it.

I leave mine plugged in all the time and it's cool right now. Not even warm. The charger that came with mine originally didn't work at all. This one is perfect!

Warm to the touch. Mine has not been hot. But, suspect my voltage is not that low.

Well, most of the time high temperatures means way up in the 100s degree, I don't think anybody uses that battery charger in those hot temperatures, and the only reason they say that is because heat decreases the battery life, you are not gonna use that in high temperatures are you?

I don't know if this normal but mine has continued to work even though it gets hot.

It doesn't start charging if the temperature is below a certail degree for safety measure. But you can warm the charger in a warm place then take it out and quickly hook it up to batery and plug it in. That way it starts charging even if it's very cold. It's a great charger over all.

I've only noticed it get slightly warm when it was charging and I was watching youtube videos simultaneously, that's only happened once or twice, though, other than that I haven't noticed anything.

When my charger was working normally it would get a little warm with a full load of D's. I attributed this to the workload and didn't have issues until the whole charger started to go. When the charger starts to die other batteries would give false readings but the Ds favor reading as bad. You'll have to charge them one at a time after that.

Mine is the same way. It seems this is a weak point in the charger's design.

Edward I couldn't say for sure but I have to say I am happier and happier the longer I use this charger. Think it is something you would be happy with. I also have noticed that it doesn't heat up.

Seems to get pretty warm but I wouldn't consider it hot. Really like the way it works. I have it hooked to two batteries in my fishing boat and just hook it up after fishing and let it charge and maintain the battery.

It sounds like you are over driving the power of the adapter and certainly the cable should not get hot. If it is attached to a phone then check the phones spec's for the correct power rating of the adapter.

My radio gets warm when charging which is normal when charging most batteries. But it does not get excessively hot.

Yes. In fact, the instructions say this charger is ideally suited for maintaining the battery during cold weather. Most electrical devices (in general) produce a little heat as electricity passes through. During normal operations you will feel this unit get a little warm to the touch. This is normal. Colder weather is actually better for this charger because it helps keep the unit cool, thus extending the life of the charger. Excessive heat is an enemy to electrical circuits, as it is with rechargable batteries and most other things. When computers were first used, they were kept in refrigerated rooms to keep the circuits cool, otherwise, the heat generated would burn the computers up very quickly. The same goes with most electronics. The cooler the unit, the better off you are. I use my Schumacher SE-1-12S year round (especially during the winter months). Be careful never to attempt to charge any battery that is frozen, however. If the battery fluid (electrolyte) is frozen, bring battery into warm area to thaw before charging. Finally, do not expose charger to rain or snow. Hope this helps. Alex, Griffin, GA.

I've had mine for a few weeks now and I like it. It works with my Galaxy S4, with the receiver module placed by the battery. I have other chargers that really makes my phone hot. The LuguLake charges my phone nicely without making the phone hot or without making too many crazy beeps at different times. The great thing about this charger is that you can take it on the road to keep your phone charged. Customer service is really good, too...

Any battery under a charging condition will get hot,reason as elecricity passes to its inner cells to charge them,they will get warm/hot,same as using an electric blanket,where one will not feel the wormth of it until it is pluged in.I hope I have answered your question to your satisfaction.karl lawar

As far as cold weather performance, I'm now disappointed. I tested it today with both the car and the just-charged powerall cold, at -15°C (5F). It doesn't work. But there could be something wrong with mine and maybe it's not fully charged. While charging, it stayed at the 3-led level for 4 hrs. So I dis/reconnected charger, and suddenly it goes to 5 leds and stops. Something's weird.
