This ISelector Power Unit is a one piece unit, plug and play. There is a power button on the top of the unit. This is a beast of a power station/surge protector. It offers a lot of power, and you can hear the internal fan, keeping it cool. It doesn’t get hot to the touch while in use. There is an area on the underside that does get warm to the touch though. The fan opening is on the right side, so make sure you keep that clear. It has 2, 3 prong outlets and 10 USB ports. It also has 10 slots on top to stack your charging phones and tablets. I love the power in this unit. For the specs, this unit has 10 USB ports, that can all charge at 2.4A 5V. This is a 5V 21A 105W unit. It’s a beast, and I love it, lol. We all have higher powered phones and tablets. We also have a lot of other items that charge via USB. It has built in surge protection. Its Peak current is 15000A, and its response time is 1NS, Surge energy 1700J. It has the Smartflow IC Technology in it, so it can detect what your particular item needs, and delivers it up to 2.4A. For example, a basic IPhone can charge on 1A. My phone only trickle charges, unless it gets at least 2A. That’s a good difference. I love how you can charge a ton of items at one time, and it doesn’t slow down your charging. My other chargers are going to annoy me now, lol. You get instantly spoiled by the power in this unit. I love how well my unit is working. I’ve had no issues with mine. I am comfortable recommending it.

I was afforded the opportunity to review ISELECTOR’s 21A 10-Port USB Charger Stand Charging Dock Station with 1700J 2 Outlet Power Strip Surge Protector(Black), in exchange for an unbiased and honest review. This product arrives as shown.
