Can something go wrong with the charger that would cause it to overcharge a cell phone

The function of this USB charger / power pack is just to provide a regulated 5 Volt output at its USB port. It is up to the receiving device (your cell phone) to decide how much current it needs to recharge its internal battery. The charging is done only when your cell phone stops asking for more current. So the answer is NO.

I tried to charge a iPhone 5 and an iPad Mini and it fried the charger out. Mine could of been faulty and it may not be a common problem.

A lot of times gps features in cell phones will make them get hot when powered on. Doubtful this has anything to do with charger. I would make sure output matches that of your phone's original charger.

I cannot answer that question. I think from all I have read about this charger it cannot overcharge or undercharge its built into the charger. I use mine to charge my boat trolling motor and when the green light comes on I always disconnect it. I have never left mine on to continually charge. Some battery chargers will damage the battery if they don't switch to the maintenance cycle. But once again I think this battery charger it's all built in to not overcharge. That's why I bought it. Hope this helps some. I am just telling you how I use mine and I have never left mine hooked up past the full charge. Sorry.

I asked an engineer at work about this. As long as the voltage matches, and the amperage does not exceed the limit of the charger, the device that is being charged will take only the electrical energy it requires. It won't hurt it. If the amperage of the device being charged exceeds the amperage limit of the charger, the charger may burn out.

No, that would be a function of the unit being charged, but I'm not sure there is a danger of overcharging with phones, etc. This unit is not as strong and , therefore, as fast as your regular USB cable from a wall plug.

If you have charged it completely and it is failing to charge your phone, then it may be a defective.

electronic over charging protection devices are not infinate life devices and have been known to fail safe, and not. why take the chance?

No issues. But he said he plugs it in to charge, and when it gets to 4 bars he unplugs it, so he doesn't think he has ever over charged it. So probably not much help.

I honestly don't know - I love the charger I bought, it works great. But the best thing to do is check with the manufacturer, or go to their web site and read the specifications. It may hurt to overdue it, and it might be fine. I really don't know, sorry.

I should mention. Ihad to re solder the electrical on the phone end. It wasn't a big deal since I was familiar with soldering. I wouldn't let that stop you though. This is a fast, great charger. If you have an issue, any phone repair shop should fix it permanently for probably relatively cheap.

This has never happened to me and I have 5 of these chargers. They are not very well made but they worked for me. What kind of battery were you charging on it and did you set it to the right cell setting when you charged said battery?

yes I don't see why it would not work, you should use a charge controller to prevent overcharging

I'm using my standard charger. It works and I never really considered it as a problem.

According to the information I read the built in charger is a float charger meaning it will not overcharge if left plugged in. There is something else offered if you keep it in your vehicle, they will send you mail when it will need a recharge based on when it was last charged. I might add I am very pleased with the performance of this unit.

No, this is not normal. This model of charger is poorly designed and is overheating and melting its own case. It's a fire hazard and you should stop using it.

I don't think you can overcharge the battery with the charger. It has an automatic They last a bit longer than the original one. But not much of the difference.
