This device will boost shore power by 10% if you’re at an older marina that doesn’t have 240V 50 amp service. Had an issue while staying at an older marina that had residential 220V which was 208V .This will burn up your AC compressors if not addressed. Also useful in some of the Bahamas where shore power is not always great. Think they cost around $1700.00 new. Asking $500.00 plus shipping or local pick up Flagler Beach FL. Pretty heavy so I would expect shipping to be pretty hefty cost.

Re: Wards Power Boost Transformer
Timing is everything. I just bought one of these from Ward's in June. It seems to me that the price was more like $2,700.

Re: Wards Power Boost Transformer
Interesting. At my marina I get 180 Volts. Not good. I might be interested - but I also have to check actual voltage, my meters might just be off.
How big is that thing? Do you strap in onto a dock post or mount it in your boat?
Is the boost adjustable on it with different taps on the transformer or is it just fixed at 10%?
Also were are you located?
ThanksLast edited by Bob Quinn; 12-04-2022 at 04:30 PM.

Re: Wards Power Boost Transformer
The device is about the size of a shoe box maybe a little longer. It’s designed to be portable but it is rather heavy. I don’t think it can regulate anything. The way it was explained to me, and I’m no authority, two kinds of 220 Volt service. Residential 220V and commercial 220 V. 220 residential is actually 208 volts commercial 220 is 240 volt. Most marinas when I would plug in would show 240v on my panel but occasionally older marinas that have not had power upgraded to commercial 220 would show 208v . If your showing 208v and run your AC units you risk burning up the compressors. This device when plugged in line from shore power to the boat will boost the incoming voltage to allow you to run your AC system without hurting the compressors.
Let me repeat that I’m not a AC power expert but this is what was explained to me.
Hope this helps.

Re: Wards Power Boost Transformer
In North America, the terms 220V, 230V, and 240V all refer to the same system voltage level. However, 208V refers to a different system voltage level. In North America, the utility companies are required to deliver split phase 240VAC for residential use. That is two 120VAC (+/- 5 %) legs.
You had it backwards but it was a good explanationScott

Re: Wards Power Boost Transformer
I used to see these used in the Bahamas back in the day. It’s a fixed boost so if you do have correct voltage your going to be over voltage by whatever the boost is set for.

Re: Wards Power Boost Transformer
o.k. thank you.
I won't be able to see what I have going on until spring.
Don't hold it for me obviously.

Re: Wards Power Boost Transformer
You don't need it if you already have isolation transformers because you can add a switch to your transformer to do this same function.
