In this video Driveway Dudes Will unboxes and tests the 70mai model PS01 budget car boost/jump starter and power bank.
We bought it from a well known Chinese website and it cost us less than €50 including postage and taxes (currency exchange rate at time of purchase).
It’s looks like a regular power bank that would charge your smartphone or tablet though it is a little bigger and bulkier with claims that it can start any 12V car, van, suv, motorcycle, truck, etc with a dead battery.

Claims by retailer :
11,100mAh battery
Start current 250A, Peak current 600A
Can jump start a 100% dead battery in seconds
Designed to jump start a 12V 4.0L petrol/gasoline or 2.0L diesel engine up to 40 times on a single charge.
Has eight intelligent safety functions, short circuit, over charge, over current, over voltage, over discharge, wrong terminal, etc.
Can operate in extreme weather from 20°C to 60°C.
3 mode LED.

Will tested it and apart from a couple of failed tries due to the crocodile clips not making a good connection to the terminal points it did indeed jump start his Alfa Romeo 146 1.4 T Spark that had a completely dead battery in it.

It was a nice 20°C day so Will could not test it in extreme weather. He did not want to try a reverse polarity connection as we have seen other boost jump boxes fry when trying this. The LED light may be useful in the dark. A bonus would be the usb port to charge your smartphone or tablet when you are driving after jump starting your car, van suv, etc.

Overall conclusion is that after getting a good connection to the battery terminals with the not so good crocodile clips it did indeed jump start a car with a dead battery.

NOTE: If your vehicle has jump points then use those and do not attempt to connect this directly to your battery as you may fry your car electronics.
