# Power Power Power

I have seen people around asking about RV power and things a like. One of the common things I get asked is how much can I run, what is the difference between the plug at my house 30amp and 50amp.

So lets talk about a few basics (WARNING there is some math here) Volts, Amps and Watts along with Watt hours

**VOLTS:**
The best way to explain volts and what we care about here is something like water pressur, higher the volts more pressure to move the electricity along with less heat - This is why those big wire voltage lines carry thousands of volts.

**AMPS: **
Its the Strength of the power, similar to how fast water is traveling in a current.

**Watt: **
Watts is the power usage - Here is the math that is important - You take the

(Volts x Amps = Watts)

**Watt Hours: **
This is how many watts you can run something for an hour -- So think about it like a gas tank you will see batteries that are in watt hours or amp hours - This is how much "Fuel" or "Electricity" that is in the battery

**Amp Hours: **
Similar to Watt hours you will see batteries that have 50amp hours of storage. So you take volts x amps = watts so if you have a 12volt 50amp hour batter you have 600 watt hours. So you could run a 100 watt light bulb for 6 hours before the battery goes dead.

So with that lets talk about some power sources that you can plug your RV into.

**Standard ol' power plug at your house**
Most of the time these are 15amp 120v standard house old plugs so with the math formula above we take 120v*15amp=1800 watts that I can use

**30 Amp RV Service: **

120v*30amp=3600 watts

**50 Amp RV Service: **
Ok this one might get some folks as this one is a little confusing.
50 amp RV Service is at 220 volts NOT 120 volts

220v*50amp=11,000 watts

Ok now you are armed with all of this good information how do I use it?? A/C Unit: 13.5kw - Watts 1850

Microwave: 1000 watts

Blower Dryer: 1000-1500 watts

Side by Side Norcold: 600-850 watts

I ll add more to this blog over time but I really hope this gets everyone started on understanding their power consumption and needs.
