Cordless Power Tools: One Battery, Every Job
Why One Battery Platform Changes Everything
Walk onto any jobsite today and the cords are disappearing: battery tools now handle drilling, fastening, cutting, grinding and yard work that used to demand mains power. The catch is always ecosystems - buy one brand's drill and you are locked into its batteries. We designed around that.
The entire ETpower cordless range runs on one 21V platform: one battery, one charger, and a growing family of tools that clip onto both. This page shows what is on the platform, what each tool is for, and how to choose the right set - for a crew or a private-label line.
Why a shared platform wins in practice:
- Cost. A battery costs a fraction of a tool; buy one pack and charger, then add bare tools as work demands.
- Uptime. A flat battery is a thirty-second swap, not a lost afternoon.
- Simple training. Every tool has the same battery release, charger and power indicator.
- OEM flexibility. We make batteries, packs and tools ourselves, so your brand can run across the whole line.
Cordless Power Tool Buying Guide
Ignore the marketing numbers and read these five:
- Voltage (V). 12V is light DIY; 18V is the classic trade standard. We build at 21V - the same architecture as 20V Max, across a whole platform.
- Torque (Nm). 24Nm handles wood screws; 45Nm drives larger bits. Impact wrenches span 280-1300Nm for car lugs to structural bolting.
- Speed (rpm / bpm). Higher speed means faster drilling; a variable-speed trigger stops bit wander.
- Battery capacity (Ah). 1.3-2.0Ah for occasional use; 4.0Ah and up carries a full shift.
- Chuck (mm). 10mm for general drilling, 13mm for masonry; 1/4-inch hex for impact drivers, 1/2-inch square for wrenches.
Brushed or Brushless?
Brushless motors run cooler, last longer and are more efficient under load, which is why they dominate professional ranges. Some ETpower models are brushless-ready as an OEM option; tell us your duty cycle and we will spec the right motor.

Cordless Power Tools FAQ
Is 21V the same as 20V Max?
Yes, in practice. Both are 5/10-cell 18V-nominal packs that reach about 21V fully charged; brands label the same architecture differently.
Can one battery power every ETpower cordless tool?
Yes. That is the platform promise: one 21V battery fits every tool, so a spare pack keeps the whole kit running.
What battery capacity should I choose?
2.0Ah for occasional use; 4.0Ah or higher for full-shift work. Start with two packs and a fast charger.
Are your cordless tools brushless?
Some models are brushless or brushless-ready as an OEM option. Tell us your duty cycle and we will spec the right motor.
Do you sell bare tools without batteries?
Yes. Most export orders mix kits and bare tools so customers grow a kit at their own pace; ask for the bare-tool price list.
How long does charging take?
A 2.0Ah pack charges in roughly an hour; we supply chargers matched to your market's voltage.
Can you build a private-label cordless line for us?
Yes. We make batteries, packs and tools in-house, so your brand can run across the whole platform: colours, logos, manuals and custom capacities.
Which kit should a new customer start with?
For general use, the 21V drill driver plus one spare battery; for a crew, the combo kit; for the garden market, the blower and chainsaw.
