Does it prevent overcharging?

It does not no, you'll notice below the item are other items listed as bought by the others. The amp charge controller is what would regulate that.

I do not know if there is a mechanism to prevent over charging. For your second question: there is an LED with various patterns of blinking to indicate charge level. "Slow red blinking: 0-50%. Slow green blinking: 50-80%. Fast green blinking: 80-99%. Solid green: fully charged."

Yes. I think the combination of charging and discharging is offsetting depending on the draw of the item you are charging...example...might take longer to charge both items this way, but they are both charging.

Not sure on the first question. The blue light stops blinking when it's done charging while plugged in so I assume it doesn't over charge. But I can't say for sure. It gives me a good charge with just the solar panel it has. If I leave it in the window all day I can charge my Samsung GS3 probably twice every three days. If I put it in direct sunlight (I live on the bottom floor of a split level) it does even better than that.

I usually keep it charged when using it, so I'm not sure if it does or not.

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.

All modern electronics now have circuitry to prevent overcharging. On this device there is an LED to indicate charging status. While charging, the LED is red. When complete, the LED turns green.

Manufaf said this- IMPORTANT: Do not charge for more than 8 hours at a time. Overcharging can damage the unit andvoid the warranty. Under normal use the unit will need to be recharged for 8 hours every 60 days.

Tigs, it will only overcharge from a direct connection to the cigar lighter socket if your vehicle's voltage regulator is faulty. Your vehicle's voltage regulator also keeps your car's starting battery from overcharging.

No, the battery cannot be overcharged. But I would not leave it on 'charge' indefinitely.

This does not over charge, once the charge is complete it does not keep charging.

This charger does have an auto shut off feature that's suppose to shut off the charger to prevent overcharging. I haven't needed that feature, so I can't tell you how well it works, only that's it's available.

Its probably not a bad idea to avoid an overcharge however we do not have one on ours yet. We do not keep ours hooked up all the time for that reason and have not had a problem.

absolutely. The breakers prevent from overloading the circuit ONLY. This device protects against surges, high voltage, low voltage, open neutrals or grounds, etc. Small price to pay to save several thousands worth of electrical devices

I have used this to charge my kindle fire, with no issue. That said, I do not know if it can overcharge. I only use it when I travel. It charges fairly quick, charging my kindle and cell phone during flights. By the end of the flight, I pack up the cords and my electronics have been topped off.

It has a gauge you calibrate according to outside air temperature before starting charging. Personally, I just use the gauge to get me into the green zone on the gauge, or when the system is blowing cold air on your hands (in the vehicle). Overcharging will defeat its purpose.
