Reddit mentions of Halo Automotive HA-i800S Power Inverter, 800-watt

This is an awesome idea. I build a thing like this for a booth on a convention floor and it was a hit. Some ideas:

1. Get a power inverter, like this one: https://www.amazon.com/gp/product/B00NA2HIX2/ref=s9_cdx_hd_bw_b2RkW_g86_i2?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-3&pf_rd_r=VY3PF1TC48091EXT0X2P&pf_rd_t=101&pf_rd_p=6b028c8a-ad84-590f-982f-2fa5ea11de64&pf_rd_i=583328
   
   It's got two built-in outlets and a regular USB port as well for up to three connections in case you need more, but you'll only need one, because you'll also be using:

   These are awesome and charge FAST. You'll want to offer a higher price for these, and people will be happy to pay it.

3. Something like this: http://www.ebay.com/itm/like/281615827457?lpid=82&chn=ps&ul_noapp=true
   
   Maybe three of them. Then no matter what phone a person has, you've got it ready for them.
   
   In theory you could do up to six phones at a time, but any more than three and they'd all have a longer charging time.
   
   Now that you've got the two-outlet power inverter, get yourself one of these: https://www.amazon.com/Updated-Elecrainbow-Portable-Rotatable-Operated/dp/B00UY9T11G/ref=sr_1_4?ie=UTF8&qid=1469671597&sr=8-4&keywords=portable+led+light
   
   This will illuminate your sign in the evening. They generally charge up quickly, or you can just leave it plugged in.
   
   Hope that helps. Keep us posted here!
