I have never reviewed a desk clamp version of a surge protector thus this Tripp Lite TLP648USBC desk clamp surge protector review is a spare set ‘loaned’ to me by a good friend of mine. Her tech-savvy husband bought 3 sets through an online promotion and she asked if I would like to review one of their units, I agreed in a heartbeat. 🙂

Since I have never tested and evaluated such a surge protection device before, I decided to conduct the review at my workshop. From the moment I received the package, I was eager to explore its features and put it to the test. Let me take you through my first-hand experience, from the moment I opened the box to my thoughts on its various features.

First Impression of Tripp Lite TLP648USBC Surge Protector

Overview of Tripp Lite TLP648USBCWhen I first picked up the surge protector, the first thing that hit me was its weight. At 1.72 pounds (0.78 kg), I would consider bringing it along for day-to-day commuting purposes if not for its bulky power cord.

The dimensions ( 5.3 x 2.7 x 5.2 inches) of the surge protector was slightly chunky for my liking if I were to bring it from place to place.

As I set up it on my work desk which has a flat wooden surface, the clamping part was initially acceptableTripp Lite TLP648USBC Side until I start plugging in some of my electrical devices for charging. The body of the device started to sway slightly as I plug in more devices – the spring-loaded clamp does not offer a tight grip on the edge of the table – my table was possibly too thin for it to get a tight grip.

Cable management might be something you want to consider if you were to get this desk clamp surge protector. The plugged-in power cables will sprout out from both sides of the device and it can be quite challenging to cable manage the power cords if you are a tidy freak like me. 🙂

As I inspect and test the surge protection device further, I ended up moving it to one corner of the desk which is adjacent to the wall. From that position, I didn’t have to worry about accidentally kicking the power cords which caused the desk clamp to tilt. The USB-C and USB-A ports worked just fine, charging up my iPad and my running watch was relatively fast without any major issue.

In a Nutshell Review
  • Cable management might be a slight challenge for you since there will be power cords of your plugged devices sprouting out from both sides of the desk clamp. For me, it wasn’t much of an issue since I placed the desk clamp on a corner of the desk adjacent to a wall.
  • This desk clamp supports up to 2.5″ (in thickness) desktops that come with a flat surface in order to secure a tight grip from this spring-loaded desk clamp surge protection device. But if you do not mind it swaying a bit here and there from time to time, it does help trim some serious real estate off your work desk.
  • The USB-A ports offer very average charging speed, do not expect too much from them – using them to charge things like iPad will take a while but smaller items like USB mice, and wireless keyboards will do just fine.

Tripp Lite Desk Clamp Surge Protector TLP648USBC

This spring-loaded desk clamp surge protector managed to reclaim quite a bit of real estate on my work desk and the USB-C port provided pretty decent charging speed. The high price tag and low Joules rating of 1080 Joules are probably the only minor flaws that I can nitpick. Overall, a good quality surge protection device that comes with lifetime limited waranty.

Pro Tips

If the edge of your desk is too thin to fit into the desk clamp, you can also place something in-between as a wedge. E.g. a packet of tissue paper or a small piece of cloth should do the trick. This will help prevent the desk clamp from swaying too much.

Who Should NOT Buy It?

While the surge protector’s spring-loaded clamp accommodates desks up to 2.5 inches thick, if you have an exceptionally thick workbench or tabletop, the clamp might not provide a secure fit. In such cases, getting a normal surge protection power strip would be more appropriate.

 Minor Flaws – What to Expect
