UNBOXING

The device comes in a compact luggage style case, which is made out of quality plastic material. Also, it is very light and portable. 

Once you open it up, you can find all the contents, which are stored very neatly. In addition, the inner side of the case is covered by a soft foam material for a better protection of all the contents. 

The star of the show is the battery, which is made out of rubberised plastic material. It is very compact considering that it has the capacity of 9000mAh.

It has 3 key features that include a power bank to charge any device, which can be charged via USB port, car jump starter and the flashlight.

The great thing about this battery is that it has a little screen on the front side, which shows the amount of juice left and some other info like the output of amps when charging a smartphone. 

The backside of the power bank is where you can find a triple LED flash, which can serve either as a flashlight or SOS light for emergency situations. Three LED lights are bright enough to light up a dark area, but would not replace your Maglight. 

On the top side you can find a port to connect jump start cable and it is covered by a flap. Also, there is a proprietary charging port, which is I think a bit of a let down since you have to carry a supplied charger and not your regular micro USB charger. On the other hand, you are getting both a wall and car charger with to make sure it is powered up all the time. But you may not even need these chargers at all and I will explain why a bit later in this review. 

Last but not least you can charge your smartphone via USB port at the speed of over 2A. 

On the left side there is a power key, which has a great tactile response. 

All right, we have to check out the selling point of this device as the battery is said to be able to jump start your car even if the battery is completely dead. 

The charging clips feel like a high quality material and would not break after a few times. In addition, the attached brick has a display to show you if you connected it to your car’s battery correctly or not.  

IS IT REALLY ABLE TO JUMP START YOUR CAR?

The ability to jump start your car, which has a dead battery sounds amazing on paper… and a bit unrealistic if you consider how tiny the 1byone power bank is. 

In order to make the test as fair as possible I tried to jump start my good ol’ 1993 Toyota Corolla since it has been left to die almost a year ago and it has quite a bit of rust and dust.

Literally, nobody has even touched it for about a year and I’m not even sure if I will able to wake it up from a death. Well, let’s call it a deep sleep and hope we can do something here. 

Please watch the video to see how it works! 

HOW IT WORKS

What we have to do here is to connect a red colour positive clamp to the positive terminal and the black clamp to the negative terminal of the car’s battery.

Then you have to connect the other end of the cable to the power bank and press a little start button on the adapter. 

At this point, the jump starter has entered into the working stage for 30 seconds countdown and right now you have to go ahead and start your car. 

It works!!! It is actually quite impressive that this tiny power bank can jump start a completely dead car’s battery in a matter of seconds.  In addition, I’ve tested it a few more times on this car and on 2008 Honda Civic and it works as advertised. 

CONCLUSIONS

So there you have it, a neat little gadget, which can easily jump start your car or charge any USB powered device on the go. The amazing thing is that if your car’s battery dies in the middle of nowhere, you don’t need to call your friend to help you out. 

What is more, a great feature of this jump starter is that once you jump start your car, the vehicle’s battery fully recharges this power bank automatically in a matter of seconds. That’s why you don’t even need to bring any proprietary chargers. 

In addition, this device has all kinds of security tricks like spark-proof technology and reverse polarity protection, so you won’t harm neither yourself nor the battery in any case. 

Finally, the 1byone car jump starter is an amazing piece of hardware and I don’t see any shortcomings. Well, the micro USB charging port would have been a nice addition, but hey, you are getting both a wall and car chargers, and sometimes you don’t even need to bother about charging the power bank up at all. 

All in all, you are getting a multi-functional, lightweight and portable solution that, in my opinion, is worth every penny.
