Overview
Wahl's Lithium Ion Pro Series Model 9766 is a cordless rechargeable clipper kit built for grooming dogs and cats with thick to heavy coats, using a stainless steel blade and lithium-ion battery.
Cordless operation trades outlet dependence for a fixed runtime, and here that runtime is 2 hours per charge after a 3 hour charge, worth checking against how long a full grooming session actually takes on a heavy-coated dog. Its lower buyer volume and rating compared to other clippers suggest it suits a specific grooming need rather than being a general-purpose pick.
- Cordless lithium-ion pet clippers, Model 9766
- Stainless steel blade for thick to heavy coats
- 3 hour charge time, 2 hour runtime
- Rated for small and large dog breeds
Who it's for
Owners grooming small to large dogs with thick or heavy coats who want cordless freedom of movement over a corded clipper. Less suited to owners wanting the longest possible runtime per charge for back-to-back sessions.
Strengths and trade-offs
Drawn from this product's published specifications.
- Cordless lithium-ion design for freedom of movement
- Stainless steel blade rated for thick to heavy coats
- Suited to both small and large breed dogs
- 2 hour runtime per charge, 3 hours to fully recharge
- Lower buyer volume than other clippers in its category
Performance notes
The stainless steel blade is driven by a lithium-ion battery pack, giving 2 hours of cordless runtime after a 3 hour charge. That runtime covers a single full grooming session on most dogs but leaves less margin if grooming several pets back to back without recharging in between.
