Adding a second battery pack to your IcyBreeze will allow the flexibility to run for longer periods by swapping batteries when the first one out of juice or to charge one battery while the other runs your IcyBreeze. This larger battery pack is ideal when longer run times are necessary. The 10AH battery pack will power an IcyBreeze v2 up to 6 hours, has a built in charge indicator, and is weather resistant.
Works great and lasts much longer than expected!
Recently my gf and I bought a small vintage camper and thought this might be a good idea. Well we haven't gotten to use the camper yet but.. I'm sitting in my living room with Icybreeze on "extreme cool" on low and I'm quite comfortable (it's 90 degrees) . Also trying the 12v 10ah battery. Been going for 3+ hours. So far so good.
