DB 600 A Jump Starter Works Great! Built very solid. Excellent build quality. I purchased this mainly for high a compression motorcycle engine. Starts on the first try now.
I also tested its ability on a V8 engine with the 1000 CA battery completely disconnected. From unit 100% fully charged, it jump started the engine 10 times, and also jumped my motorcycle 4 times; and ONLY drained the unit to 72% indicated.
VERY IMPORTANT....When jump starter cables are plugged in to the unit, they are immediately live and hot instantly, even with on/ off switch to off. On/off switch only activates the USB portion. BTW, from 100%, unit drained down to 60% and charged phone 3 times.
Therefore, it will probably charge your phone 9 times from 100%, and it will probably jump start your car more than 20 times based on my testing of a V8 engine, from 100%. Its light worked very well and bright.
For 65$ on Amazon, and 3 yr warranty, this is a very good buy! I spent a great deal of time researching the different ones on youtube, and went with this one because of its quality and warranty. There were no good videos on this unit, so I made one myself:soon to be posted. My 2nd choice would be the Uxcell 600A for 48.99, but it did not have digital display, and build quality seemed inferior to the DB 600. There are most likely 3 diff manuf. out of china, that make all the diff models.
