Always want to hook the positive (red) cable first then the negative (black) ..if there is a spike or arc when connecting its much safer for the arc to follow the ground to the frame then send the spark through the power side.
The car's battery was connected while the car was being started. The car would have started on it's own without the YESPER so what did this prove except that this guy thinks you are too stupid to catch on? Next time disconnect the battery and hook up the YESPER directly to the cables only. Damned salesmen.
Since you posted this question a year ago, I suspect you have already found your answer? But if not, just hold down the power button until the flashlight comes on. You can then press the power button again to strobe the light, and again to send SOS, and once again to turn it off. Of course, you better hope there is a retired Navy seaman watching your Morse code, because millennials won't know what the flashes are!
how do you tune it off. No way how to charge this. Do you throw it away after the the battery is depleted. There is no way to charge this. I will be taking it back. Crazy. To just use this one and then throw away.

The blue usb c port is in or out power. It can charge there with a cellphone charger etc.
If you are looking for instructions or real demo, find another video.
If you are looking for an enthusiastic infomercial, you are in the right place.
Quick note. This also started a 1995 Jeep Wrangler without a problem
the Yesper is a decent Jump Starter but it doesn't like the cold, even when fully charged.
Can this be charged for continuous use or is better to get one that has a wall charger?

Great video, keep up the good work my friend..
I just bought one and it’s omitting an Oder when charging. Are you experiencing this?
Didn’t the car battery start it? It would have been a test if you took the car battery out of the equation.
Made in China, (and can be bought online from China) but what isn't these days,.. especially when it comes to batteries.
I used mine on a Ford Galaxy 2 litre diesel with flat battery DID NOT work . I have tried another type and that didn't work either.
What is the operating temperature range? Can it be safely left in the hot car in the middle of summer (180 degrees or more)?
140 degrees read it
how do you charge it.
I just bought one, the flashlight doesn't work
How do I turn turn it on?

Turn off ur wipers dude 😂
After you jump start a few cars. There is no way to charge this jump starter. How can they make something that you can not charge. How stupid is that.
You charge it by plugging in the USB-C cable to a wall charger, just like charging your cell phone.
How long do you charge it for right out of th box
