Several years ago I bought an automotive jump start unit with a built in inverter, a PEAK power Station 700. My intent was to also use it as a field power source for photographic lights. Unfortunately when I plugged in two 300 Ws strobes the thing died after about two flashes. I have since ordered a 1350 VA pure sine wave battery backup for that use. https://www.newegg.com/Product/Product.aspx?Item=3DN82E1684210 2133 ($124.95 US with promo code EMCRCRK39.) Should I expect any problems using this device with the strobes? I usually use three or four at a time. =20 I have another higher capacity standalone inverter but I am afraid to try it as it is not pure sine wave. =20 If I ever get time to attempt a repair of the PEAK unit I will probably seek advice from this list on that also as I have no experience with inverters. =20 Thanks, Allen --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
