One of the ways to increase the time a strobe or a camera can run for a longer durations, is to use an external battery for power. Some cameras and strobes have a dedicated port for receiving external power, and some don't. But even if they do, the device that provides power is usually a propitiatory one and only fits one specific device, so the cable to power an SB800 is different than the cable you'd use for, say, a Canon EX strobe (assuming you have both :)
There is a solution to get around this power problem. Use whatever external power you can source with the built in battery chamber, mimicking a battery set. The options we shared before involved crafting a wooden dowel to fit the exact size of a battery, or using uncommon electrical connectors for the same end.
Reader Jake Carvey just shared a cool tip regarding this method with us. One that made me slam my head into the table. Jake suggested using battery upsizers for mimicking the internal batteries, eliminating the need of a wooden dowel. Click to continue ›
