Frequently Asked Questions
Does it come with battery and charger?
Check the option you pick — the kits include battery and charger as shown in the options, and bare versions are for people already in the same battery family. The listing notes which is which.
What voltage does it run on?
3.7V, which is standard household here. No adapter, no converter, nothing extra to buy.
Is it powerful enough for real jobs?
The power specs are in the title — this class handles home repair, automotive, and workshop jobs properly, not just light tinkering. Match the torque or wattage to your task.
How does the torque compare?
The torque rating is in the specs — enough to break lug nuts and drive structural fasteners in its class. The variable trigger and modes keep it gentle when the job is small.
How long does the battery run per charge?
The runtime is in the specs — a full repair or assembly session per charge for the standard jobs, and spare batteries keep bigger projects moving.
