Using the DeWalt DWST08050 ToughSystem 2.0 Dual - Port Charger is simple. First, place your DEWALT® 20V MAX* or 20V/60V MAX* FLEXVOLT® batteries in the charging ports. You can charge two batteries at the same time. If you need to power your personal electronics like your phone, just plug it into one of the USB ports. When it comes to storage, you can add this charger to your TOUGHSYSTEM® modular storage setup. It has enough room for your batteries and small tools. As for the handle, it's coated for a comfortable grip when you need to move it around. Here are some important things to keep in mind. Make sure the charger is placed on a flat and dry surface. Avoid using it in extremely hot or cold conditions. When cleaning, use a dry cloth to wipe it down. Don't expose it to too much water or dust, as it has IP55 protection but still needs proper care. This will help keep your charger in good shape and ensure it works well for a long time.
