Great Product  Time owned: more than 12 months
My previous station's backup was modeled on the designs used in some of the GMDSS consoles that I was maintaining. Fast recovery,dedicated charger across a battery(ies)that was swiched into the distribution buss by a drop-out relay across the AC power supply's primary. Charging status was monitored by a Heart/Xantrex link 10. The system worked very well with only a glitch at switch over. When we moved into our present location, there was simply no room for a shack. Whatever could fit into a small computer armoire would have to do. Everything sat on hold for a while untill I seen the first powergate advertised. Only systems with diodes forming an OR gate that I've worked with had been trickle back-up supplies using resistors or bulbs to set the charge current. The lower loss of the schottky diodes looked interesting. Still no way to fit a high current charger and linear supply into such a small space. The PG40s changed that limitation along with a switching power supply. The combination with a Rigrunner 4008 mounted on the back wall allowed me to replicate the previous system along with the Xantrex battery monitor in a very low profile and compact manner with one optima bluetop AGM battery and have plenty of room to spare. Setup by jumper took minutes and the rest was wire distribution and crimping to finish the job. As the other's have noted, the only con is the powerpoles themselves. In my installation, they are hidden out of the way and not likely to get bumped. The system is running flawlessly along with a PC UPS for the computer. Power switch over to the entire station is seamless during an outage. Without the dual function of the PG40s's step charger, it would have been difficult to achieve the same capacity as before in a much smaller space.

Works well  Time owned: 6 to 12 months
I now have two of these units, one for a portable emergency VHF station (see and the other for a power module I plan on using for an emergency HF station. Since I use AGM batteries I adjusted the power supply output voltage upward and shorted the jumper inside each Powergate unit as per the instructions.

For the emergency VHF station I use an 18 AHr battery inside the station housing, with an external 33 AHr battery as a backup. An Astron SS-18 is the power supply. For the other setup I use a Group 24 80 AHr battery (brand name Werker from Batteries Plus) and an SEC 1223 power supply.

The battery voltage is monitored with either an analog Simpson meter or a slick tricolor LED circuit from Steve Weber KD1JV (slightly modified, see

I did a measurement and found that if the battery is connected to the PWRgate PG40S with no load there is still a small 0.5 mA drain from the battery. Since both of my setups are backups and I do not maintain a constant float charge, I now disconnect the battery when they are not in use and recharge the batteries every two weeks.

Pricy, but well-made and provides seamless transfer from power supply to battery. I agree with the previous reviewer's concerns about Powerpoles and heavy cables, but in my setups this has yet to become an issue.

Excellent Product  Time owned: 3 to 6 months
Overall, an excellent product. This version of the Powergate includes a stair-step charging platform and the ability to charge a wide variety of batteries, including AGM and gell types.

In my application, I use a 80 AH Optima Blue-Top AGM marine battery in conjunction with the Super Powergate, and an Astron RS-35 power supply to distribute 12VDC to a West Mountain 4012 RigRunner. The switching between the Optima battery and the Astron supply is absolutely "glitchless."

The only negative comment relates to the use of the Anderson PowerPole connectors. Although there are work-around approaches to cable management, the connector's design is defective from the beginning: the connector body really requires a quarter-turn or similar type of threaded barrel to lock to its mating surface.

The problems I am seeing have nothing associated with the manner in which the connector is soldered or crimped. The problem is that the connector easily unseats when it is stressed. And, when using heavy gage wire in these power supply applications, it takes little cable movement to unseat the connectors which creates a hazardous condition in high-current applications.

Excellent choice for UPS  Time owned: 0 to 3 months
Can't really add anything here except to give it a great rating. Does what it says. I use it with a 75AH AGM battery, so I increased the Astron's voltage to 14.5v and changed the internal jumper (which was easy to get to - very nice mechanical design!). The switch from house power to battery power is flawless. All-in-all, a really nice alternative to a dedicated charger setup. A little pricey perhaps, but it's turnkey.

Works as advertised  Time owned: 0 to 3 months
The other reviews sum it up.

It also works great with your exisiting power supply to charge gel cells as well.

One minor suggestion to make it more versatile would be for the battery charge rate to be selectable by switches instead of using fuses as jumpers. I have different size gel cells so switching between 1 4 7 and 10 amp charging rates would be easier with switches.

Nice backup system  Time owned: 0 to 3 months
I just assembled the following components to provide backup battery power for my HF/VHF/UHF (FT-897D) rig:

- Deka 8G31 98aH Gell cell battery ($140 locally)
- Group 27 plastic battery box ($11 locally)
- PWRgate ($120) - attached to battery box
- RigRunner 4010S ($120)- attached to battery box

Considering the price of a set of internal batteries and charger for the Yaesu FT-897D, the system described above provides much more utility to power accessories and much longer battery life for an additional investment of a few dollars.

The setup remains portible for emergency use, although at 65 pounds the backup system sacrifices convenience in favor of extended battery life and functionality.

With 1/2" of ice and snow forecasted for this evening, it is fun knowing that communications will continue without interruption and we can power a 12 volt light and scanner for a few days.

Excellent product!  Time owned: 0 to 3 months
Works just like the PWRgate PG40, but includes a staging charger. Selectable current ratings for the charging circuit (1, 4, 7 & 10A). Plugged in my battery, it dumped max current until a preset voltage (selectable for Gel or AGM), then changed to a preset voltage until 1/10th of the chosen current is reached, then switched to a float setting to keep it topped off. Just like the older model, will switch to the battery when the line voltage drops below the battery voltage, so turning off or disconnecting the power supply causes an instant switchover. I don't run a lot of current through mine, so the immense heat sink fins haven't warmed up yet.

Would definitely recommend to anyone - and the use of PowerPole connectors makes it simple to add into any existing system!
