It looks very tiny. If I use all ports to charge my stuffs, does it have over-heat protection?

This wall charger limits the output power to 20w, so i don't think it would be very hot.

The Neptune does not have a cover that goes over the USB port as in previous models. The connectors look like they are gold-plated so that probably keeps them from becoming corroded, therefore not requiring further protection.

Dear Demetre,I am the kind of guy who keeps useful extra items. The darn hub didn't work when it came. I read someone's comment that the power adapter was too small, so I looked in my stash of power packs [some people call them "Wall Warts!"] and found one rated 5V 1Amp. Since then, it has worked, but it's junky - the sockets do not fit smoothly. I notice that everyone else is using 3 - 5 Amps. The item they sent to me was tiny and it was much weaker than my 1 Amp unit.

Yes. The ports correspond to wattage output. Using the wrong port would cause a higher watt device to charge slowly or a lower watt device to overheat.

No, its a trickle charger and the current isn't enough to cause an overcharge. I have left it connected for long periods with out ill effect

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 wouldn't trust it to charge anything. Gets super hot within 30 seconds, so hot you can barely touch it.

It has a blue LED that's pretty well blocked when both ports are occupied. I haven't opened it up so I'm not sure about protection. The housing states 2.1A max per port.

I used mine to replace a charging port on a Acer laptop.worked ok, but was tricky. don't overheat the connections! use as little heat as needed to melt the solder. don't overdo it on the heat. hope this helps.

When I Travel I run A fish Tank pump,500 w heater, Heating pad for the wife, charge her cell phone her I pod sometimes all at one time no problem (cooling fans don't even run) As good as A PURE SINE I don't know what your idea is for a lot of electronics. If you mean A LOT as in A LOT I would say NO.

Honestly I have not noticed, my Mac never seems to over heat. No matter how long or how much work I performUsing it. I believe the construction of the case still somehow allows sufficient air flow. However if it is a concern for you, perhaps search for another case, but from my experience I have had no problem or complaints with it!

No, I have had mine pluged in ever since I got it. No problems at all, overheating isnt a problem, it also seems to be able to take a decent amount of punishment. I had droped mine right when I opened it. No problems even after that.

I am using 12 of the 16 ports and it does not get hot. In fact it is barely warm at all

I have one of these and charge Samsung and iPhone's on it (and up to 4 devices simultaneously). However, there are no AMP markings over the ports and the "owners manual" that came with it does not specify. With a supplemental power supply, you shouldn't have any issue charging, but it may not be "rapid charging".

The plug in the back flips out for charging and is setup for a standard 110 outlet. It basically uses the electrical current to dry the micro beads inside, changing their color from Pink (wet) to Blue (dry). I have not taken it apart, but I am sure the higher voltage/current will overheat and damage this unit. Even with 110, it gets very hot. It will only work in a small gun safe less than 25cu ft.

I have never noticed it getting hot. I am not sure about confined spaces. I do like the quality and feel and convenience of a multiple usb port charger with a separate cord allowing charging in more convenient locations.

Yes, the power supply is included and we use it for longer period but there is no problem with overheating.
