The battery is a reliable companion in the world of adventures! It can charge not only familiar gadgets but also allows you to connect directly to the terminals of a car battery anywhere, without needing outside help. With the battery, you can start a gasoline engine up to 5.0 liters and a diesel engine up to 4.0 liters if the vehicle's onboard network voltage is 12V. Unlike jump starters without a built-in battery, where you first need to charge the jump starter with the remaining charge of your own or another battery, a charged battery can immediately provide enough starting power for a successful engine start even in the middle of nowhere. The connectors on the housing support fast charging of peripheral devices with fast charging protocol support. The built-in flashlight at the end has 3 modes: normal, strobe, and will definitely help during work in the dark. Starting current: nominal up to 1000A, peak up to 2000A Charging input and output 5V, 3.9 3.12 15 3 20 3.3 1: 5 2.4 9 2 12 1.5A 2: 5 2.1 Output with a round socket: 12-15V, up to 8A Battery capacity: 16,000 mAh Operating temperature range from -20 to Built-in flashlight Hard case for storage included.
