Portable Car Jump Starter for Gas or Diesel Engines

The brand's previous page addressed the question "Why doesn't it start sometimes?" The potential reasons include a virtual power situation due to the long transportation time, and the possibility of the product being damaged during transit. To address this, it is recommended to charge the product for 4-5 hours before first use.

Moving on to the product description, the BM502 Jump Starter is a powerful device with a peak current of 6000A and reinforced smart clamps. It can reliably start all 12V dead batteries easily and safely in 1-3 seconds. On a single full charge, it can provide up to 50 jump-start cycles for cars, motorcycles, trucks, boats, and even heavy-duty vehicles with gas engines up to 10L or diesel engines, even in extreme temperatures ranging from -20°C to 60°C.

In addition to its jump-starting capabilities, the BM502 also functions as a backup battery charger and power bank. It has two smart USB ports, including an 18W Quick Charge Port, allowing you to quickly and safely charge your mobile devices simultaneously. With its exceptionally low self-discharge rate, the battery jumper can maintain its charge for up to 12 months, providing you with peace of mind and constant backup power during your travels.

The BM502 also features built-in emergency LED flashlights with three modes (lighting, flashing, and SOS), which can be used for up to 48 hours continuously. This makes the battery jumper a versatile and indispensable tool for emergencies or adventure trips, helping you find your way in dark or difficult situations.

The jump starter's heavy-duty clamp cables have been updated to extend the reach to various battery terminals, with improved conductivity and a larger opening range for easier use. Moreover, the device is equipped with 8 built-in protections and visible alarms that automatically detect connection issues, ensuring a safe and worry-free operation.

Finally, the BM502 features a large, user-friendly LCD screen with a backlight, making it easy to read even in direct sunlight. The screen provides clear information about the battery level, operational status, and any potential errors, giving you complete control and transparency over the device's performance.

It is important to note that due to the long shipping time, the battery power may become virtual, and it is recommended to fully charge the device before the first use to avoid any issues with subsequent charging.
