Bolton Technical 90W Car Charger
This 90W car charger from Bolton Technical supplies 20V at 4.5A through a 7.9mm by 5.5mm round connector. It draws power from a 12V to 24V cigarette lighter socket in a vehicle. The adapter is compatible with a wide range of Lenovo laptops including ThinkPad, IdeaPad, Edge, and 3000 series models.
Drivers needing mobile power
The unit suits professionals who operate Lenovo hardware from a car or truck cab and whose devices match the listed connector and voltage. Buyers whose vehicles only provide a 36V lighter socket cannot use this charger. Users with laptops requiring a different connector size or a voltage other than 20V must select another adapter.
7.9mm by 5.5mm connector fit
The single specification that determines compatibility is the 7.9mm by 5.5mm round connector paired with 20V output. Only devices accepting this exact plug geometry and voltage will work reliably with this accessory.

Questions about this item
How do I install the 7.9x5.5mm connector and which step causes the most issues?
Plug the 7.9x5.5mm barrel tip into the laptop power port and the other end into a 12V-24V cigarette lighter socket. The common mistake is using a 36V socket, which the charger does not support.
What maintenance or replacement will this 90W car charger need over time?
The charger has no user-serviceable parts. If the 7.9x5.5mm tip or cable sheath shows wear, replace the whole unit to maintain 20V 4.5A output.
What limit appears first when running the adapter at full 90W load continuously?
The 12V-24V vehicle socket rating is the first bottleneck; if the lighter fuse is below the charger's 4.5A draw, it will blow before the adapter overheats.
