Holiday gift buying season is upon us, and if you’re anything like me buying gifts is a huge pain in the ass. My dad is a tech geek and my father in law has a flip phone, which means a lot of digging is necessary to find the right gift for them.

The 1byone Multifunction Jump-Starter is essentially the best of both worlds: both a tech gadget and a necessary tool. Conversely, this is also a great gift for your friend or family member who has an old car beat up car but has a $500 smartphone.

For those who have devices to power, the 1byone works just like any external battery and it does a fantastic job. During a road trip I was able to fully charge my iPhone 6+ and that was after being used for its primary function. Although it works great as a backup battery for smartphones and tablets, it’s truly designed to jump vehicle batteries.


If you’ve ever had to jump a car before, you know what a pain in the ass it used to be. If you are jumping a vehicle from another one you need a pair of cables and of course another car. The older portable options work great, but they also weigh anywhere from 8 to 20 lbs, and take up quite a bit of space. This particular unit only weighs 9.8 ounces and is about the size of two iPhone 6 pluses glued to each other (5.3 x 2.8 x 0.9 inches).

There are two versions by 1byone, but this particular is a 9000 mAH until with a 12 volt output. This means it can typically jump a 4.7 liter engine or lower without a problem. Compared to some of the other competing small jump-starters, this also has a larger battery capacity, which makes it great for a device backup charger. It takes about 3 hours to fully charge the device.

The 1byone has the typical external device charger look with a sleek matte black finish. Paired with a backlit LED screen, covered port for the jump-start adapter, it’s weight and minimalistic interface, it’s a simple to use resource.

The only negative component is the length of the cables. They are quite short, which can make finding a good grounding spot challenging. However, even with my motorcycle I was able to clamp it onto the chrome exhaust and it was fine. It also comes with a great hard plastic carrying case with foam inserts.


As a jump-starter, the 1byone does an awesome job and it is also idiot proof. Before triggering the adapter to transfer its juice into the battery it automatically will detect if the clamps are on properly. If the polarity is reversed (negative on positive and positive on negative), it will not kick on. It also won’t spark when you touch the two clamps together, and yes I did try.

For charging a device like an iPad or smartphone, the 1byone can tackle enough of the bar to put them in the green. It also has fast charging capability and shows you what the output is on the LCD display. During a road trip I plugged my iPhone 6 plus into it and went from 85 percent to about 100 percent in about 30 minutes. For this, it had a 2.1 amp output and drained the 1byone by 10%.

To recharge the device, it typically takes 3 hours. It comes with both a wall and car charger, so regardless of location it can be charged back up.

Overall Conclusion

When I judge a gadget it’s usually based on a few basic components: It works as advertised, it does the advertised thing well, and usually a wild card point for coolness, design, or even value. The 1byone Multifunction Jump-Starter hit all points across the board with ease. The design is sleek, it’s more than just a battery jump starter, it’s cheaper than the bulky jump starters from yesteryear, and it works exactly as advertised. I will note that if you are looking for just a portable device charger that this particular unit wouldn’t make sense based on the cost; however, if you have a car this is easily worth the extra $30. It’s currently priced at $77, and is usually listed as $88.

1byone Multifunction Jump-Starter score: 5 out of 5
