A good product but beware if you have a very tight micro pc case
Very fast speed and looking well made. My speed test shows very fast speed as described in the specs of this product. However, if you have a tight case like the tiny micro pc it may not fit! Teh heat sink is thick and it may cause problem. I have Intel NUC Skull Canyon and it does not fit! Luckily I can remove the heat sink for the memory module so I could fit it in. The heat sink is not really needed but I guess it can help the unit stay cooler and run at the fastest speed.

It works for a good price
So far, it works. I can charge it with my Apple USB-C charger (97W) and it seems to charge very quickly to full capacity with a couple of hours. It's very quick to get to 50% (well under 1 hr). It could power my Samsung Chromebook Pro without issues using the supplied cable. I can power my Surface Pro 4 using a different cable I ordered on Ebay. I monitor the charge rate and it is good when the laptop is lightly loaded but under heavy load, it is no match for the power adapter for the Surface Pro (this is expected). I think at this price point it is good and doing its job as claimed.
It seems to flash 188 when there is an issue and flash the level of charge in the battery (0 - 99) when it is being charged. Otherwise, it just shows the level of charge remained in the battery. I have another ROMOSS 30000. I like the feature that shows the Voltage and Amp. It would be nice if this model has that feature too.

Dell E-Port PR02X USB 3.0 Docking Station give a new life to old DELL Precision workstation
I have an old DELL M6500 precision workstation. It is 7-8 years old and solid like a tank delivering higher performance than most new laptops out there. This dock gives it two new Displayport 1.2 and extra USB 3 ports. This means I will be able to attach more QHD monitors at 2560x1440 resolution and perhaps even 4K UHD monitor at lower refresh rate of 30Hz. This gives it an extended lease of life. I can have access to extremely reliable technology of engineering class without having to pay the original prices at 10x the price for high quality used computer equipments. And it provides plenty of power for normal every day work with rock solid reliability.
I also bought a DELL 2415q UHD 4K monitor. Even though the DELL Precision M6500 and its Quadro FX 2800M graphics card are only certified for QHD resolution 2560x1440, on Windows 7, it instantly recognised the DELL 4K monitor and set resolution automatically to 3840x2160 @ 30Hz. I then tried to create custom resolution at higher frequencies. Finally the whole set up could work reliably at 3840x2160 @ 40Hz. I am very happy even though it would be best at 60Hz. The reliability and the beautiful new 4K monitor all shows the good engineering from DELL and Nvidia. Old tech still works beautifully with new 4K monitor.
