YESPER Boost Jump Starter Battery Pack 4120A 27000mAh Car Battery Charger Jumper Starter (All Gas/up to 10L Diesel) 100W Quick Charge 12V Portable Jump Box for Totally Dead Vehicle with DSLI Safe Tech

Q: Will it start a completely dead battery?

I started a vehicle with stolen battery, just use "boost" button. This button forces voltage to be present from YESPER even when no voltage detected from target. The normal safety protocol requires target voltage to be detected before YESPER will supply voltage itself this safety is YESPER proving correct cable hookup. In my nobattery present jump the Vehicle started right up and remained running. Obviously, target vehicle died the instant I removed YESPER and I did not let YESPER stay connected but a few seconds. The point of here is to say yes, it will start when a vehicle with a totally dead battery.

Q: Can transport it abroad?

Dear Customer: Which country are you from? If you are interested in our products, we are willing to arrange another shipping specially for you. For further communication, you can email us. We provide a timely online response for our customers. Sincerely Yesper

Q: Is this yesper set up to allow for faster home charging, like using a 30w usb c charger wall adapter? or some other way to speed that up? thanks!

No box say's 15 watts input! Got one from amazon works great.

Q: If after hooking this up and cranking the starter it does not start what steps need to take place to try and start it again?

Ok...when you read the little booklet it will tell you...there is a little button near the blinking green light you press to fully energize...that should get you your solid green light.
