the jackery is also approved by bose at least that what was said on their forum. It comes with a charger for wall outlet or car or you can buy solar panels. my kn1000 pulls 16 watts playing loud and the bose compact pulls 30 watts playing loud. The Jackery 500 has 518 watt hours and a 1000 watt peak surge cap. I can tell because the jackery tells you how much power you are using. how this helps.
