The SundpeyPRO 21V cordless ratchet is a battery-powered 3/8-inch ratchet wrench that turns fasteners for you. It comes as a kit with two batteries, a charger, eight sockets, adapters and a carry case. It is aimed at work like car repairs and assembly, where a slim head helps in tight spaces. Here is what the specs mean.
Torque and speed
SundpeyPRO states a maximum torque of 75 ft-lbs (100 N·m) from a 21V motor, which it describes as a pure copper motor. The trigger controls speed across a range of 0-300 RPM. In general, a powered ratchet spins fasteners on and off far faster than a hand ratchet. It is not an impact wrench, so very tight or rusted bolts may still need a breaker bar or a different tool. Check that the torque figure suits the fasteners you work with.
Compact head and light
The head is slim and the tool is lightweight, at about 4.5 lb (roughly 2 kg) for the listing's weight, which helps in confined spots. A forward/reverse switch sits on the back of the head and can be operated one-handed. A built-in LED lights the work area, and an indicator light on the side shows remaining battery power.
Two batteries
The kit includes two 21V, 2.0Ah (2000mAh) batteries and a charger. SundpeyPRO says each battery gives up to one hour of runtime when idling, so the figure under load will be shorter. Swapping between the two lets you keep working while one charges. The brand advises fully charging before first use and storing batteries removed from the tool in a dry, ventilated place.
Built-in protections
The brand lists 30A overload protection on both the motor and the battery, which cuts the power if the current goes over the limit. The battery also has over-charge, over-discharge and over-heating protection. Follow the manual for charging and storage.
What is in the case
- 3/8-inch drive ratchet
- Two 21V 2.0Ah batteries and one charger
- Eight sockets: 10, 11, 12, 13, 14, 15, 16 and 17 mm
- A 1/2-inch drive adapter and a 1/4-inch drive adapter
- A 3-inch extension bar
- A user manual
The listing notes that you may find grease at the head, which the brand says protects against rust and lubricates the spindle. It also advises opening the case from the side with the SundpeyPRO logo to avoid dropping the contents.
Who it suits
It suits home mechanics, DIYers and people doing repetitive assembly who want to save wrist effort. Because the sockets are metric only, it fits best where metric fasteners are common.
What to check before you buy
- Fastener sizes: the sockets run 10-17 mm; check whether you need imperial sizes or deeper sockets.
- Torque needs: compare 75 ft-lbs with the torque your fasteners call for.
- Battery and runtime: consider whether two 2.0Ah batteries cover your job length.
- Socket type: check whether you need impact-rated sockets for heavier work.
- Storage: check the manual for charging, storage and temperature guidance.
- Safe use: read the manual and use eye protection.
