I rarely shoot on locations, always feel more comfortable working in the studio. In most cases there is a power outlets on location, I had only a few where it was too far from the lights (warehouse freezer, for example). With no external power I’ve used 4 Canon speedlites, but they too weak to be used with serious light modifiers or on a large objects.
\nIt makes me feel very uncomfortable when I do not have enough power:-)<\/p>\n
<\/p>\n
So, I was looking at Vagabond II<\/a> or similar portable power solutions, but did not find the one I like: it should be powerful enough to run 3-5 strobes equal to X1600 (1600 effective\/ 660 true WS) for at least 300 pops and to be not expensive, as I won’t be using the system often, therefore do not want to invest lot of money in it.<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.photigy.com\/school\/wp-content\/uploads\/2019\/02\/1-47.jpg” alt=”DIY portable power system for Paul C.

It was a simple fix of adding of a thermistor to the AC output. It certainly dramatically lowered the current load presented to the inverter from the strobe, in this case a single 250 Wsec unit).<\/p><\/blockquote>\n From this:<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.photigy.com\/school\/wp-content\/uploads\/2019\/02\/5-30.jpg” alt=”DIY portable power system for Paul C.

For example, if the energy rating of the strobe \/ flash is 320 Watt Sec, the surge power rating of the inverter should be more than 320 Watt Sec X 4 = 1280 W. An inverter with surge rating of around 1280 W or above will thus be suitable for this strobe \/ flash \u2013 e.g. Samlex America, Inc. inverter Model No. PST-60S-12A that has a continuous rating of 600 W and a surge rating of 1200 W.<\/p>\n<\/blockquote>\n
\nI am not the first who did it, I found this simple guide<\/a> to be the most helpful.<\/p>\n
\n<\/p>\n
\nAt the beginning of each recycle, each X1600 WL unit will draw a peak current of about 18A for about 200 milliseconds. With 3 units connected, a draw was much more then 650 watts, and inverter shuts down to protect circuits from overload.This is the key, our inverter should handle it differently: reduce the voltage under the heavy load, this will give enough time for capacitors to be charged.Unfortunately, this is no such information can be found on the inverter specification, only our community mind can help us here:-) Correct inverters are made by Samlex America<\/a>. The 150 watt model is exactly\u00a0 (at least some people believe so) the same unit used in Paul C. Buff Vagabond II system (Update:<\/strong><\/span> I was wrong here, 150 W on vagabond I, and 400 W on Vagabond II).I bought PST-30S-12A<\/a> (300 W) model here<\/a> for $140 shipped.
\nThe battery<\/strong>: Vagabond II has 20 Amp Hour(s), so I went for 35 Amp Hour(s).\u00a0 It should have enough juice to run for 75% more pops than vagabond, but still to be not too heavy or too big for more or less comfortable use.
\nI’ve got Powersonic PS-12350NB<\/a> (almost like a Panasonic<\/a>, but cost 35% less) battery: 27 pounds sounds just right for me:-)
\nThe battery charger<\/strong>: Following Jacob’s advise, I’ve got SUPER SMART BATTERY TENDER JR.<\/a> for $20 shipped. 700 milliampere should get a full charged battery in one night, and it also has car adapter if you need to do it during the trip.
\nThe bag<\/strong> (AWP 8″ Electrician’s Tote<\/a> – the link is for 10”x8”, but I’ve got 8”x8” bag) and miscellaneous accessories such as a wires, switch, etc I’ve got from a local Lowes store.
\nWooden plates, black mate paint, a soldering iron (I’ve used a torch light), two hands and two hours of\u00a0 my time between my lovely family and my precious tools were enough to complete everything.<\/p>\n
