The ECOXGEAR EcoJump is a portable and waterproof lithium-powered jump starter for vehicles with 12-volt lead-acid batteries (cars, trucks, boats, ATVs, motorcycles, etc.). It is designed for easy and safe use, with built-in reverse polarity and spark protection. It features 500-amps at 12-volt cranking power, giving users 25 jump starts per charge in a small, portable package. The EcoJump uses Bluetooth Low Energy to send data to the EcoJump App on your smartphone (available for iOS and Android) whenever your smartphone is within range (typically about 30 to 60-feet). You can configure the App to display pop-up warnings when the battery charge level is low or if the unit is outside the recommended storage temperature range. This will help you ensure the EcoJump is charged and ready for use when you need it. The EcoJump can stay over 50% charged for up to 6-months when in Standby Mode. It can stay over 50% charged for up to one year in a cool location when in Off Mode, but will not send BLE notifications. Temperature and other environmental conditions affect how long the EcoJump will stay charged while n storage. The EcoJump can be charged by connecting the included USB cable to the EcoJump’s USB micro input port and then to a wall socket (using the included 5-volt AC adapter) or to your computer. Charge time from low to full charge is approximately 7-hours. The EcoJump has two 5-volt USB output ports to charge devices, such as a smartphone, tablet, or action camera. Device charging rates are similar to the charging rate when connected to the USB of a desktop PC (approximately 1.5-hours from low to full for most smartphones, depending on the device, battery specifications, etc.). The integrated ultra-bright, 200-lumen LED flashlight has multiple modes and provides up to 200-hours of operation at low or 50 hours at high. The hazard light has red lights that flash in a triangle pattern to serve as a roadside warning and safety alert.
