I just leave my iPad or iPhone plugged in overnight. Seems to be working fine.

When the charging is done (100%), the charging signal is still on, it will keep it at full charging. In the manual book, it says it has surge protection. I put five devices on, just regular warm but not heat or burn. Hope this helps, Thank you

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.

yes you must buy a type of charge controller that prevents your batteries from being over charged or over discharged. a pwm (pulse width modulation) is a good affordable choice for charge controllers. i think the one i bought was 60$

No, Anything over a 5w panel and you want to run it through a charge controller first. You risk overcharging a battery (which will eventually kill it) if you don't, even 5w is pushing it unless its a 70ah+ size battery and it has a constant small draw from it (Like in a car where electronics are being run even when the car is off)

Yes. While they seem to be somewhat tolerate to overcharging you can ruin them. I've left them for 12hr and had no problem. But when I forgot about one and left it for a day. It was ruined. It just wouldn't hold a long term charge anymore. I had used it quite a bit so it may it was just its time to die but all the others I've had have lasted a very long time.

Yes, Internal over-charge and over-discharge protection to prevent battery over use.

You need to run thru a charge controller of some sort in either case to prevent overcharging.

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.

The green light stays on (solid green).More description on the back of the device.Also you shouldnt worry about overcharging most modern devices should have a mechanism to prevent overchaging as a standard.

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.

You cannot overcharge the battery so don't worry about it. Also no harm done if you undercharge. I have had mine for years, and to be honest do not charge it regularly, and have not had any problems. These are really just guidelines.

I would suspect it does not have overcharge or float mode to protect from overcharging. There are several out there that are made specifically for maintaining a full charged 12 Volt wet cell battery for around $10 to $15. I use one by Cen-Tech for an old Jeep I have to keep the battery charged.

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.

With any electronic device you can't over charge it. You have to do what's called cycling the battery. Charge to a hundred then run down to 15 or 10 percent. Over charging the lithium ion could damage or even destroy the powercell. I use the same product and it lasts me all day and some times into the next

This is a question to ask of the manufacturer. I would think their is protection in the charge controller to prevent any damage, but I have no knowledge of that.
