Bed Power outlet. Battery Backup

I received two battery back ups for computer use. I am wondering if I was to mount one in the truck bed somewhere and plug it into the ac outlet in the bed, if it would provide more or longer term power if we were to go camping or was on site using power tools.....any thoughts on that?

 

Check the run time when on battery. Depending on the AC load, I bet it will be in minutes assuming the batteries are healthy and fully charged.

 

How big was the UPS? Most small ones are only 7 AH the bigger ones 15-18 AH's not a lot of run time.

 

Not a lot of run time and not a huge capacity.
Computer UPS systems are designed to filter and condition line power to protect the computer, and to give you enough run time to safely save your work and shut down when power does fail.

The battery backup isn't going to allow you to run higher current items without blowing the Taco's inverter... You'll have to unplug the UPS to run more than 400 watts, since even with a conditioning UPS, it still draws from the line if present. The batteries are only used when line power drops.

To get significant power and run time, you'd need something along the lines of the Clary SP1250, which will crank out 1250 watts.
It also costs in the ballpark of $6,000, is a 4-space rack unit, and uses six 44ah batteries.
And once the batteries are dead, it'll blow the Tacoma inverter recharging the batteries.

Power tools are going to blow pretty much any inverter.
Better off with cordless tools and use the inverter to drive the charger.

 

Most of the bigger high output UPS are high voltage DC setup (90-120 volt lots of batteries) but they still use relatively small batteries they are not looking for long run time just enough power to keep things running until they can safely be shut down. Have a look at the inverters power rating and figure you'll need the same amount of power to recharge as it outputs a light weight UPS is in excess of the output of your truck inverter. If you want power for some thing like what you are talking about add an extra battery to you truck and an inverter on that battery. You can use a standard isolator system used on any motor home to isolate and charge the two batteries. We use some pretty big UPS units at remote transmitter sites again only to keep things running until the generator starts.

 

So what's the bed power outlet good for then?

 

Car salesmen.

Seriously though, it has come in great handy for me while camping. I powered a box fan once in the northcountry in June when the bugs were so bad that no bug spray was any good. I also use it to power a small air pump to fill an air mattress. As long as you don't expect too much from the outlet, it's great to have.

 

I have used my power outlet to run my sawzall with a 50' cord
And use it for my makita grinder as well
I love my outlet
It saved allot of people during sandy
Gutted 17 houses with my truck and its little inverter
As for a good battery system i use a 12 volt battery i got from radio shack
Its used to backup alarms and such
And i use that to power 12 volt outlet in bed of truck
It powers radios and charges phones and i even run a small fan off it
It lasts at least 3 days with radio and iphone running off it
This way i don't drain my battery when everyone needs to charge something camping and such

 

With the engine running, 400 watts. Look at the power tag on what you want to run. Small tools yes coffee pot, microwave no.
