3. H2 will automatically power up the connected electronic devices.
Cautions: This adapter cable is just a connector adapter, and it does not
have any electronic circuits inside to control electronic voltage/current/polarity.
It only provides physical size and shape conversion.
Please make sure the power source voltage /current/polarity are all correct for
your applications when using this adapter.
FAQ:
Q1: What are the features of the H2?
A1: Apart from jump starter function, the H2 can be used to recharge virtually any 5V
powered USB devices, such as mobile smartphones, tablets, portable gaming system,
digital cameras, camcorders, and portable GPS devices, etc.
Besides, it can power up any 12V electronic devices, such as vacuum cleaner, car waxer,
air compressor, and portable freezer, etc. by using the 12V output cigarette lighter
adapter. It can also jump start a drained car battery with the included Sparkless Smart
Cable. It is also equipped with a built-in ultra-bright LED flashlight.
Q2: How does the Sparkless Smart Cable work?
A2: If the green indicator light is on, means ready to jump start; If the red indicator light
is on, means a misconnection between the clamp and the battery terminal; If no light is
on, press the BOOST button for 3 seconds until the green indicator light turns on, by
which time the jump starter is ready for use. If the red indicator light is blinking, means
the Reverse Charge protection is activated or Low Battery.
Q3: Will reversing polarity connections of the jump start cable damage the vehicle?
A3: Not at all, the H2 is very safe with Sparkless Smart Cable. If you accidentally connect
the RED and BLACK cable clamps to the wrong polarity terminal and attempt to jump
start the vehicle, the Sparkless Smart Cable (the red indicator light is on) will cut the
power immediately to prevent injury and avoid damaging the vehicle.
