Very Good Product  Time owned: 3 to 6 months
Seems to do what it says. Very happy with extremely low voltage drop, instantaneous switching between supplies and ease of switching out parts without losing power to equipment. Used to upgrade my power system and provide emergency backup power. Ultimately hope to add solar panel to system.
One minor problem with mine- when I first plugged into USB port, the port physically came right off! Appears to be a poor solder job on the anchor tabs, altho rest of unit looks good. Will see how well WMR follows up on this.

works great  Time owned: 0 to 3 months
I bought this PWRgate on November 20, 2017 from DXEngineering. It is working fine. It has jumpers inside the case to set the battery type and charge current. But of you leave them off you can set the parameters with a utility program that can be down loaded from the West Mountain Radio website. The utility program is called WMR Diagnostics Utility. It enables the USB – COM port. If you double click on the line EpicPWRgate in the program, a window opens up that shows the information coming from the unit. The window is a serial port program. I stopped using that one and switched to a program called PuTTY. It is a serial port program too, but with it you can save the data in a log file. If you type S in the serial port program, the PWRGate will let you view and set the parameters. If you keep pushing enter without entering anything, it will show you the current settings without changing any of them. The Epic PWRgate sends a line of data once a second. It sends the state of the charger, charging, Trickle or power supply off, etc. Each line looks like this “Charging PS=14.36V Bat=14.16V, 0.26A Sol= 0.08V Min=36”.
I like this feature because I can make sure I leave the power supply on long enough to fully charge the battery. I added a fuse to my battery like the manual for the PWRgate states. I bought it at an Overton’s marine store. I also added a toggle switch to the battery mounted on the plastic battery case. The switch allows me to turn off the battery when my power supply is off. That stops my radio equipment from running down the battery. I found that the equipment draws current even when they are off, especially if they have a USB port connected to a computer.

RFI when charger is running  Time owned: 0 to 3 months
WMR is known for making great products if not pricey so I was expecting more of the same. The power gate portion works well, and has been improved to reduce the loss and heat of previous products by using power MOSFETs instead of lossy diodes.
The manual warns of RFI from the charger, which is shared by both power supply or solar input, so they include a push button to disable the charger for 30 minutes so you can complete your QSO RFI free. Not sure how well this would work in a day long net operation, when could you re-charge? Operation also requires one to modify (adjust) ones 13.8 volt power supply to a higher voltage for correct operation of the charger. Some may not be comfortable with removing the cover of their PS and making the adjustment. Other issues with the charger on solar, if the panel can not maintain rated output, due to cloud cover, the charger stops, but LED indicates battery full charge (when it is not). Over all a nice unit, but some unexpected surprises from WMR.

Terrific Upgrade to PWRGate  Time owned: 0 to 3 months
As a longtime user of the PWRGate, I was happy to see this new unit, which adds a solar controller. This allows you to charge your batteries via solar automatically, even when the power supply is on. The LEDs give continuous status, plus free software allows you to monitor battery and solar status. Using it with 2 100 watt Renogy solar panels, and a 100 Ah AGM battery in the shack. Kudos to WMR for this great upgrade to the PWRGate!

An excellent update to the respected PwrGate line of products  Time owned: 0 to 3 months
I am one of the early users of this recently released product in the West Mountain Radio power product line. This new PwrGate automatically and instantly switches your attached radio and various attached peripherals such as antenna switches, etc., to 12 volt battery backup, just like its predecessor, the Super PWRGate PG40s. This new model now has an input for a solar panel and charges your battery from this panel whenever the panel is attached (and in the sun!) Equally important, the circuitry of the new Epic PWRGate has a voltage drop of .05v compared to up to .37v in its predecessor. This can allow significantly longer Tx time until battery exhaustion. Charging algorithms now include LiFePO4 batteries.

Over the past several days of use I have been using this with a 35aH AGM battery and a 100w solar panel along with an Alinco DM-330MVT power supply. I have adjusted the power supply to output 14.45v in order to fully charge the battery and get it to trickle charge. The solar charge circuitry is MPPT type. I hear no RF noise intrusion on the various bands I have used.

The entire unit is very compact. No heat sinks apparently needed and mine does not get warm from use. Firmware is upgradable with a micro USB interface. A cool feature is the ability to easily view scrolling real time data in a terminal type communication window that is a free software download from West Mountain. It installed quickly and without errors and reads out current status such as trickle, normal charging, no power, etc. It also lists battery voltage, charge rate, solar panel volts and total up time.

Bottom line, so far so good. I'm happy. My radio is happy. My XYL doesn't know.....
