The 1byone 9000mAh 12V Multi-Function Lithium Jump Starter Level of Customer Satisfaction

Why the 1byOne 9000 is our favorite jump starter.
Until the 1byOne came along the new breed of lithium ion powerbank car jump starters all offered pretty much the same benefits compared to bulky full size lead acid jump starters, ie.
- they are ultra portable
- they make great gifts
- they start a dead car
- they charge phones and gadgets
The 1byOne however brings a new feature to the table, digital readouts!
These are great for an early warning about when your charger is about to run flat and requires a charge up. There is no reason now to be stranded without a fully charged, ready to go, jump starter.
For this reason alone we have propelled this jump starter straight to the top of our lithium ion jump starter league table. That’s not all to like however, as the latest version comes neatly packed into a sturdy case perfect for storing in the rear of any vehicle.
I also liked that it came charged and ready for use – so if you have a vehicle parked up somewhere that you really need moving again, you will not have to wait for it to charge – unpack it, connect it to the battery, and you will be driving off in seconds!
What makes the 1byOne 9000 Different from other Jump Starters
The 1byOne 9000 has safety features that makes it ideal for beginners, new drivers, or inexperienced home mechanics.
- the digital charge status readout is not available on any other lithium ion jump starters we have reviewed
- a reverse polarity safety feature that we have only seen on one other model
- anti-spark protection
- Fantastic carrycase
These features together on one device make the the 1byOne 9000 stand out amongst other popular jump starters.

Common Questions for Stanley Jump Starters
Conclusion
The 1byone 9000 proudly sits in my cars glove box, ready to help any stranger or family member in their moment of need, stranded at the side of the road. I was never really keen to offer my vehicle up to jump start another car; the dangers of trying to pull up bumper to bumper against another vehicle next to live traffic, messing around under the bonnet, it’s not ideal. With this tiny device that’s all a thing of the past, you can rescue anybody with something no bigger than a smartphone!
Considering the continuous restart power, and the useful additional functions, it is no surprise that we found this jump starter in the #1 spot in at least one Amazon car category.
An Alternative Lithium Jump Starter to Consider
The Powerall is a similar size with similar functions, but no digital readout.
Just received this charger in the mail today. Very light in the case and when I.opened the case, every piece was tightly packed in foam pockets that keep everything safe and secured. When I plugged it in, the display showed 50. So assuming it was 50% charged, I left it plugged in for about an hour or so. When I checked, the display now read 100. The instructions had nothing specific on how to charge unit or what the display should read when done. So hoping my common sense is correct, I think I’m ready to help somebody, anybody (!), jump start their car.
There’s been a couple of times when at a gas station or parking lot, that I’ve been asked to help “jumpstart” a car. Unfortunately, I’ve had to decline, as I was worried about damaging my car’s computer system. Now I can help anyone needing a jump and that really makes me happy!
Yeh same here, I used to hate getting asked for a jump start, messing around with cables under the bonnet, sparking all over the place – it’s a piece of cake with one of these tiny starters though!
