How many times can I use the product to jump start a car on a single charge? – HULKMAN Help Center

Answer:

Two factors might affect the times you can jump start your vehicle on a single charge: Battery capacity and Engine rating.

Battery capacity

It’s easier to understand that the bigger the capacity is, the more times you can jump start your car on a single charge.

	Alpha 65	Alpha 85	Alpha 85S	Alpha 100
Battery Capacity(Wh)	44.4Wh	74Wh	74Wh	118Wh
Battery Capacity(mAh)	12,000mAh@3.7V	20,000mAh@3.7V	20,000mAh@3.7	32,000mAh@3.7V
Jump-Start Times	30 Starts	60 Starts	60 Starts	80 Starts

Note: The jump starter times on a single charge depends on the laboratory results, which were tested by starting a 1.5L gas engine, and may vary depending on the engine rating and environmental temperature, etc.

Engine Rating

Typically, the engine displacement is proportional to the power input it needs, indicating that a higher engine displacement requires a more powerful jump starter. For example, if you’re trying to start a pickup or minivan, you might require less power.

However, the HULKMAN Alpha jump starter features an industry-leading performance and enables the revival of almost 99.9% of dead batteries. The following table depicts the engine ratings that the HULKMAN Alpha jump starter works for:

	Alpha 65	Alpha 85	Alpha 85S	Alpha 100
Gas Engines Rating	6.5 Liters	8.5 Liters	8.5 Liters	10 Liters
Diesel Engines Rating	4.0 Liters	6.0 Liters	6.0 Liters	10 Liters

Note: We recommend you to charge your jump starter’ battery level above 80%, so that it is more possible to kick out your dead batteries.
