FAQs
Q: Is the GB500 safe to use around children?
Although it has reverse polarity protection and is spark-proof, you should never let kids use the device. When using, always keep an eye on everything.
Q: Can I leave the GB500 connected to the vehicle while not in use?
No, when the engine is not being started, disconnect the jump starter. Over time, leaving it connected can deplete the battery in the car or device.
Q: Can I use it in extreme temperatures?
Yes, but the temperature range for operation is 32°F to 104°F (0°C to 40°C). Performance or battery life may be lowered if it is charged or used outside of this range.
Q: Is the device waterproof?
Although the GB500 can withstand splashes, it shouldn’t be immersed in water. Steer clear of the rain when operating.
Q: Can it jump-start a completely dead battery?
Indeed. Though results may differ for batteries with internal damage, the GB500 can fully recover dead batteries.
Q: Can the jump starter be used on diesel engines?
Yes, but only for 3.0L and smaller diesel engines. A higher-capacity variant can be necessary for larger diesel engines.
Q: Is it safe to store in a vehicle?
Yes, but stay out of direct sunshine and intense heat, as these conditions can gradually deteriorate the lithium battery.
Q: Can I charge it while using it to jump-start?
No, you cannot charge and jump-start at the same time. Before jump-starting, make sure the device is always unplugged from the power supply.
