Dell Power Calculator

The 10 stop filter is simple to use with the long exposure calculator.

Photography in a dark room. Love the calculator being available at all times

This calculator is beautiful, stylish and perfect. Item exceeded my expectations. I would purchase again.

My Dell AiO never skips a beat in a power failure and the downloadable PowerPanel software assures an orderly shutdown before the juice runs out (or after so many minutes or seconds on battery power). The battery is replaceable. It's slim enough and well ventilated enough to lie on it's side under my desk and runs cool even when charging. Never had a problem with a CyberPower UPS. Will update if I have a problem down the line, but so far, so good.

The fact that this is the second WD19TB I buy shows that I really like this dock. (As I am working in 2 places, I wanted to have it in both!). Pros and cons: + One (tiny) USB-C plug, everything taken care of: USB devices, network, multiple monitors and even charging the device. + Very nice integration into Dell notebooks: No need to open the device. Simply push the button - or even use the plug event to power on the notebook. Can't be more convenient than that? + No Fan (like the old WD16TB dock had) + Works with all TB-able notebooks I used so far (MacBook, Asus, Dell, ..) - To get the full power output from the dock, you have to use a Dell notebook (E.g. gamer notebooks from other manufacturers might not be able to charge and be used in full power mode, even though the power brick should have plenty of power to do it - note that this is due to the USB-C spec, there was recently an addendum which might change that going forwards). - It is on the pricy side - If driving a high res monitor (2560x1440 and above) using an HDMI cable, you might get only 50Hz out of it and using many notebooks you will get a flickering (display on/off) over time. You should really use a DP cable. - It has only one USB plug at the front - which is a bit on the low side considering that you might plug in mouse and keyboard. Yes, there are more plugs on the back side, but it is finnicky to get to them once set up. - Be aware that the notebook has to be fairly close to the dock as the cable is not easy to be bend, and the outlet location is fixed (on both sides).

I bought this as an upgrade from an older Dell U2715H purchased in 2015. My older UltraSharp still worked well, but the lack of USB-C docking and power was inconvenient, and I needed to use all three USB-C ports on my laptop when working at my desk. With the U2723QE, just one USB-C plug handles them monitor, power, external hard drive, and a slew of accessories connected to the monitor. The upgrade from sRGB to Display P3 is nice, too... but may not be hugely noticeable, depending on what you're using the monitor for. Finally, the U2723QE works perfectly with the MonitorControl app (macOS only) when you want to adjust the brightness of the monitor using your Mac keyboard's brightness buttons.

This is my first review I have ever written (buying computers sine the 1970's), and only because this CalDigit Element is so good I was compelled to write. I have a new Dell XPS 15 inch 9530. I had options of purchasing the Dell WD22TB4 hub (made for this laptop) or getting the CalDigit. After doing a lot of research I choose the CalDigit because of the vast amount of thunderbolt ports. My Dell laptop had some issues like 4 motherboard replacements, 3 speaker replacements, one screen replacement and one keyboard (ALL IN THE FIRST YEAR). I was hesitant to buy another Dell product. I have my OEM Dell power adapter plugged into the USB-C (right side) to power the laptop because the CalDigit only delivers 60 watts which is no problem. The laptop understands which power to use. What do I gain from this decision. I have 3 empty Thunderbolt 4 ports on the CalDigit and one Thunderbolt 4 port on the laptop free (the other TB4 is used to connect the CalDigit). So I end up with: 4 Thunderbolt 4 ports free 4 USB - A (10 gb) available I have the best of both types of ports. I rather make my own decision as to what the port does instead of a hub having only a set determined specific device ports. This unit out performs any hub I have ever had. In fact the CalDigit's construction is amazingly well built and looks good.

Needed an upgrade to Dell mid-tower case. This power supply was an easy swap. Everything lined up perfectly and had plenty of power lines for all the peripherals. Surprisingly it was easy to tuck the extra power lines out of the way behind the drives.

I replaced the battery simply because it was over 3 years old. It would still keep my two Dell PC's online for about 23 minutes during a power outage. All the PC's in my business are protected by APC backup power supplies and have never had any problem w/ any of the 3 I own.

Just what I needed to up the power of my new Dell desktop computer to do some heavy duty CPU work.
