Using the Klein KTB500 Portable Power Station is a breeze. First, you can charge it in different ways. You can use the AC wall charger to plug it into a regular wall outlet, or use the 12V auto to 8mm barrel adapter if you're in your car. You can even use the Klein Tools Solar Panel (Cat. No. 29250) to charge it with solar energy. When it comes to powering your devices, just connect them to the appropriate ports. There are two 120V outlets for bigger devices, four USB ports (including a 60W USB - C PD port) for your phones, tablets, and other small electronics, and a 12V car port. The digital LCD screen will show you how much power is left and other important information. As for maintenance, keep it in a dry place within the operating temperature range of 14° to 104°F (-10° to 40°C). Avoid over - charging or completely draining the battery. If you notice the internal cooling fan isn't working properly, it might be a sign that something's wrong, so it's a good idea to have it checked. With proper use and care, the battery can last for about 500 cycles to 80% capacity.
