can you overcharge this device by leaving it on the charger too long
1661724
No, the charger has a light that goes from red to green when it is charged. It then stops charging.

I wouldn't do it! I only charge mine when it gets down to one bar, then charge it for no more then 48 hours.

The charger continues to charge as long as the battery is connected. You should not let it charge more than 5-6 hours or it will overcharge and ruin the battery.

You can, but its a slower charger so you would need to leave it on all the time but it will work

Yes. I would recommend you use a smart charger, like a Battery-Tender, that senses when the battery is getting charged and switches to a trickle charge, to avoid overcharging.

No, you can not over charge the battery. It does not have a charge controller but it has a voltage regulator that prevents overcharging (additionally, it keeps power from the alternator from reaching the panel). I have had mine plugged in for 7 months straight and can even drive with it connected with no problems.

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 cannot answer that question.

I would recommend taking the case off - the further distance between the charger and the device, the less the amount of charge per unit of time.

If you're asking if you can leave it plugged in then yes. I leave mine plugged into my tv. Plus I keep it plugged into the charger on tv so that it is always charged when tv is on. It doesn't over charge.

I'd not assume it's safe to leave it plugged in unless you see a statement saying that it is. In fact many manuals will say "Don't charge for more than 24 hours" or "Don't overcharge" showing that you shouldn't leave it on. If your thinking of that so it has a routine "fresh charge" that you don't need to think about doing regularly I'd get a timer that turns it on for just 15 minutes a day and/or a regulated power supply (like the Schumacher PC-6 or Coleman powerchill cooler AC supply) that won't "overcharge" it.

I don't know the answer to this question. Sorry. I just plug mine in for a few hours and have never been concerned about over-charging it. The first one I had lasted for several years before it finally died--probably from dropping it too much.

I keep my iPad, iPod, Galaxy s3 phone and Asus tablet plugged in when not in use and I have not had a problem with overcharging. I don't have a Kindle, but I would assume it would be OK as well. The GadgetSys is the best charger ever.....

yes it will not overcharge, once it drops below full charge it brings it back up. I have three of these and always leave them in with no problems

I'm sure you can as the U.S. standard voltage is 110 or 115v and the charging plug is a two pronge universal plug. The only thing I would say to do differently is to cut the charge time in half as it is twice the voltage and you wouldn't want to overcharge it. Overcharging can shorten battery life. I hope this helps you.

No, your phone or charging item cannot be over charged, but I used it maybe 2 times and the charger stopped working, I suggest not buying it.

I do not. I did not want to run the risk of any possible damage to the battery or charger. The battery holds its charge, so there is no need.

Not that I have noticed. And the charge rate is so slow that I'm not concerned about overcharging! Hope this helps!

No! The charger lets you know when it's charged. Depending on your usage, you'll get about an hour out of each charge.
