How hot does this battery pack get while it charges a device?

While charging and iPad and iPhone simultaneously, the center felt warm, but never hot. Charging just one device at a time results in no temperature change at all.

It just gets warm to the touch, not hot at all. I have loved this battery pack, wish I had purchased two.

I haven't noticed it getting hot at all! I'll try to pay closer attention the next time I use it but I don't recall it being hot at any time I picked it up - and I've used it quite a bit since I bought it!

It does get hot but not the pack. The connection at the outlet gets very hot.

I leave it on a wooden end table when I charge it. I've never noticed it being hot at all.

I have not noticed any excessive heat while this battery pack is being used.

The only time it got hot on me was when I was playing a game on my phone while it was charging (yeah I know - not the smartest thing to do!). The charger does not get hot during normal charging when the phone is not in use. However I would send a note to Anker and ask them about ventilation. Any battery or energy device generally needs some type of ventilation during use. Even Kindle says that if you have the reader in a protective cover, leave the cover open for ventilation during charging.

When I got it, I fully charged it. When I'm just on battery power. it lasts about 4 hours max. Each recharge slowly decreases the battery life. Yes, it does make the laptop hot. I use a laptop cooling pad and it keep it pretty cool. However, the pad connect to the laptop which uses more power if you're just on battery power alone.

I'm using it in air conditioned car so I didn't have a chance to test it under such conditions, anyway, I didn't notice any overheating problem when charging two devices.

Very hot? It's normal for rechargebles to get warm, even very warm, but not hot...at least not too hot to the touch.

I do not know how hot the device gets as I had it placed on he USB port on the back of my PC. I have the device to my brother who was able to install it successfully on his PC which is MS7 64bit.

No. Batteries under charge should not get hot. When mine did, they held almost no charge.

I have not had an issue with this unit overheating. I have taken it from NYC to London, to Sri Lanka to Malaysia, and no problems. It works fine and charges my phone over and over again before having to recharge the Universal External Unit.

I have had this plugged in for both an iPad and an iPhone at the same time over night and have never noticed a heat problem. Hope this helps. I use it all the time.

I never got hot with mine, unless it was (like Matthew said) heating the battery up for other reasons. Sitting near a window, heat duct, etc while charging. Otherwise i never got hot using the Nokia Qi puck.

Mine stays charged a little less than 2 hours. Sometimes my computer gets hot.

Depends on what the lowest voltage your device can function at. The battery pack voltage is lower than what you specify. It actually puts out about 12.2v when fully charged but will drop to around 10.5 to 11v as it discharges. It is not a true 12v battery pack by design.

It has been awhile since I charged mine. I do remember them getting warm but definitely not HOT. It takes between 7 to 9 hours to charge 4 Dcell batteries. For the performance I get from them in my Fenix flashlight it is definitely worth the wait.

Mine also came without a box and wrapped in bubble plastic, but has not been overheating. When it has been charging for a long time like 12 hours (that's what mine usually takes to charge a battery up), it tends to get warm, but not hot.

Had my charger plugged in for a few days with a battery from a recently purchased yard sale 18-volt drill. The unit was warm to the touch, but not hot. I have charged other batteries and they were warm when removed. The charger changes to a solid light when the battery is charged, and I usually remove it at that time. If it's getting really warm, I'd try a different battery if possible. If same result, then I would contact vendor or B&D as a warranty issue.

It does warm up a little when a device is charging, but nothing significant

If "hot" means you touch it and go "Ow! That's going to burn me," then yes, it's a problem. If it's warmer than your old battery that might have had little or no life to it, then the Anker might be OK or it might be overheating. Bottom line... Don't risk fire or damage to the computer (however, it might seriously be time to invest in a newer laptop or some other device). Return the battery and try another and see if you get the same results.
