BUTURE Car Jump Starter, 800A Peak 12800mAh Portable Car Battery Starter (up to 6.0L Gas/5.0L Diesel Engines) Auto Battery Booster Pack with Smart Safety Jumper Cable, QC3.0 USB Outputs

Product Information

Use the original manufacturer’s USB cable that came with your device and plug it into one of the USB output ports. We spent hours in our at-home lab looking at voltage and amperage in real time while charging different batteries and engines.

It's also important for sealed lead-acid batteries like this one to be charged regularly — Dewalt recommends plugging it in to top off at least once a month.If you failed to start your car, you need to disconnect the battery clamp from the vehicle and the jump starter.

In testing, we found that when using the 5V USB port, we could fully charge an iPhone up to 15 times without needing to plug in the power pack. An impressive 1200 amps peak current promises to breathe life into 12V vehicles, handling engines up to 7.Similar to the GOOLOO 2000, the GOOLOO 1200 was capable of holding an impressive charge—though it wasn't capable of reviving large engines repeatedly.

I had a question about the product and shipment but their support team responded promptly and professionally. We chose to include units capable of delivering anywhere from 1000 to 2000 peak amps, though several brands offer a higher output in other models.

The BR300 has three LED flashlight modes: Spotlight, SOS and Strobe to help you in the dark or during nighttime emergencies.
