Is it safe to use on a computer's USB port that are not designed for higher amperage? Won't it damage the port?

Probably; as the current draw increases the port's voltage will drop and the charging device will stop increasing its current draw. I got it primarily for one phone I had that would only charge on a few chargers leaving me stranded frequently - it seems the phone expected a voltage on the data pins to indicate a charger rather than a port; this corrects that problem. I also got a couple of USB volt- / am-meters to keep an eye on things and sort out chargers by power capability.

It is perfectly safe. The main benefit in this scenario will be the protection against unauthorized data transfer.The port cannot output more than it is specified. So even if you ask a 500mA port to output 1.0A, it will still only output 500mA.

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.

I think it's restricted to 2.4 amps per port, however, this should not be an issue, no device that charges using USB pulls 4 amps

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.

No, it won't harm your computer or monitor. It would be better to buy one surge protector that has enough outlets, or to plug both smaller surge protectors directly into the wall though.

It has no 'amps' per se. This is a passive,not powered, hub so it will be able to source no more total current that the USB port that it is connected to.

Yes, definitely I do that all the time. As long as you have a USB normal size(computer plug) type A, 5 volt and something around 2 amps, you will be fine

Use the USB plugin on a computer only. It requires 5volts and a 1amp supply. Yes there are power AC plug-in adapters that will work at this Volt-Amp supply. Your battery will still charge up , it will not be damaged. Read my comment below at Loftek direct below.

I'm not sure if I quite understand the nature of your question. But tell you what, I have it plugged in to my computer via a USB cord with other USB ' S plugged into it and ever since I bought it, it hasn't given me any problems. It was bought mainly for computers. There are no provisions made for outlets or sockets.

I would not use anything smaller than a 20,000 amp for a laptop. The 6,000 amp is not enough power.

No...that's what the USB shield is for..inside the insulation where the wires connect to the USB connector, there is a ground wire that should be soldered onto the sheild. It's the standard. I just tend to worry about long flexible attachments connected to my laptop that plug into my usb port...I would be very sad if it was to bend the USB connector that is soldered to the motherboard.

No. Like all USB charged devices, it operates on 5volts and low current. Besides, it's made by Sony. Its up to spec and won't damage your equipment.

I don't see an issue from an electrical engineering standpoint, assuming your AC adapter works properly, but keep in mind the cable between the two USB-A plugs is barely two inches long. You're not going to have a lot of room to maneuver.

Be careful! The USB port is not meant to provide more than 0.5A. Devices plugged into this cable may require 0.5A EACH, meaning you risk frying the USB port you're plugging into if you attach too many peripherals. I would strongly suggest you use only one port at a time, especially if connecting to a PC or other valuable device. I *HIGHLY* doubt this cable offers any protection to your PC.

I use mine with just 1 USB port for power, but apparently it depends on the drive you are using inside the enclosure. I use it for the 'old' drive in a laptop. I upgraded the internal drive and took out the 250Gb drive and put it in this case as a back-up drive.

no, it is 5 (FIVE) VOLTS only, not 15 (FIFTEEN).So if you need 15 VOLTS (which I doubt it because all USB 1.0,2.0 and 3.0 can ONLY be 5 VOLTS)If you MISTYPED and it is ONLY 5 VOLTS @ 1.2 AMPS then it WILL work, because the AMPERAGE is how much PUSH the voltage has, so it would charge a 5 VOLTS and do it quicker than 1.2 AMPS, but it does NOT give 3.1 AMPS per USB port, it would max out at 2 AMPS.

This hub does not include its own power supply so the *total* current it can supply among all four of its ports is the maximum the port it is plugged into can supply. For USB 3 ports on desktop computers, that is usually 900 ma (0.9 amps); for some laptops it may be only 150 ma (0.15 amps). So no, it will not supply anything even close to four amps on any of its ports, nor will it supply more than 0.9 amps on any one port when plugged into a normal USB 3 host port on a computer even if the other three of its ports are unused.
