This Audew 2000A Peak 20000mAh Car Jump Starter for All Gas Engines or Up To 8.5L Diesel Engines with LCD Power Display, is absolutely awesome. I have used this to start many vehicles that have had flat batteries. I have never had a vehicle that it will not start!

I got mine from Amazon, but they are no longer available there, so you have to use the direct website.
