The fishing light can be powered by any 12v, 24v, or 110v-250v system (with optional converter). Using the included battery clamps, the light can be powered by any 12v battery, but a marine "deep cell" type battery is recommended. 2 12v batteries in series (making a 24v system) will also power the light by simply clamping onto the outer terminals. The higher the amp hour rating on the marine deep cell battery the longer the light will operate. We recommend using the highest amp rating battery that is available. It is not recommended to use the boats only battery, a house battery, or a starting battery. Having a separate battery will ensure that you don't drain the boats only battery. There are also many smaller 12V batteries (ATV, power wheels) that are portable enough to carry to a dock, lake, or use on a kayak and will last for several hours before needing to be recharged. Draining a deep-cell marine battery to completely empty is NOT recommended and may shorten the "life" of the battery.
The optional 110v-250v converter will allow you to simply plug into an outlet that is rated between 110v and 250v AC. Although the converter comes standard with a 3 prong plug, it can be used with an adapter and used worldwide. When using the waterproof converter it is recommended that you plug it into a GFI outlet and keep the converter out of the reach of children. The converter may become warm after extended use.
