No - two coffee machines.
Mind you - “printer in the winter” I could knock out my invoices on site & maybe run a power washer or summat.
I’m thinking about running with A Deeper Clean’s idea and getting an electric leaf blower to sweep off lots before I clean windows. This battery thing could solve the worlds energy crisis.
For many years, I worked in the industrial scrap recycling industry in the San Francisco Bay Area (LOTS of manufacturing.)
We participated in battery recycling – they contain lead plates – by purchasing from the public as well as battery dealers and retail stores.
Later, I found out that many of the firms we sold to (in palletized increments of 20 tons per load) processed the batteries in Mexico. They would cut off the battery tops, pour out the sulphuric acid onto the ground, retrieve the lead, make their profit, and provide little-to-no cleanup. Not sure what’s going on these days…
Battery technology will assist in the world’s energy demand, but there’s always a story behind the story, even with a lil ol’ electric leaf blower.
I’m guessing those who are worried about our environment would frown on this practice.
There are a good number of printers that are considered “mobile” with a purpose of using them in the car. They have some made for high volume.
Check "oneill printers’ for example. Also HP and a number of other printer companies have rechargeable batteries in them as well. They are more expensive but they may be worth your time looking into them.
The O’neill printers look to be all “thermal” printers. The thermal paper will fade overtime, which my customers will not appreciate.
My system is so far working great. I’m printing estimates and invoices all day long and charging the battery every few days. The battery, printer, and inverter combined cost less then $300.
For this same purpose, among others, I would like to hardwire a 2nd battery to the back of my van. I haven’t done this kind of thing before, and I don’t know if is as simple as it looks like (i.e run a heavy gauge wire from each terminal to the 2nd battery)
If you have done this or know how it’s supposed to be done, please share.
It may depend on your specific vehicle. I would ask a mechanic or the guys at Autozone or Advance. You may need a heavy duty alternator to keep it charged properly.
