Digital SLR Cameras are the tools of choice for professional photographers. These cameras capture amazing photos, but require more power and higher capacity batteries than normal point-and-shoot digital cameras. For professional photographers, this often leads to problems while on the job. In a single day, a professional photographer can expect to use their DSLR for hours and take hundreds of photos and videos. Sure, you can carry additional batteries, but what happens when both of your batteries are dead and your camera runs out of power mid-photo shoot? To avoid missing out on potential revenue, every professional photographer should invest in an additional USB charger, battery charger or car charger. Below is a few of the different options for keeping digital SLR's fully powered while on the go.

There are several different companies that offer travel chargers for digital SLR cameras. The most common are compact wall chargers. Digipower offers a DSLR travel charger that is compact and can charge DSLR batteries from a standard AC wall. The AC plug folds down and is relatively easy to carry. Several other companies offer similar products, but many of these products don't have everything a professional photographer could need for their DSLR. These simple chargers lack a battery status meter and don’t charge multiple brands of DSLR camera batteries. As well, many of the cheaper generic brands don't have battery level indicators and continue charging even while the battery is full. This is harmful for the battery and affects the battery life.

Another option is the Dual-Ion DSLR camera battery charger, which has multiple functions and can charge many different brands of DSLR batteries. It is a car and wall charger that can charge two different batteries at the same time. It incorporates interchangeable battery plates, which make it compatible with the different models of DSLR cameras. As well, it has status LED indicator lights to show the real time charging progress. This is extremely useful for photographers and gives them precise indicators as to when their next battery will be ready. To avoid damaging the battery, it has a built-in auto-cutoff switch that enables trickle-charging when the battery is completely full. For professionals, this charger meets every conceivable need they may encounter.
