Wahl Stainless Steel Lithium Ion 2.0+ Slate Trimmer Model 9864: What to Know
Wahl sells the Stainless Steel Lithium Ion+ line in more than one finish and bundle code, and two of the ones we checked first, the 9864SS (chrome-style finish) and the 9864-400 (blue), both showed as Currently Unavailable on their Amazon listings. The configuration we found active and in stock is Model 9864 in the Slate finish, and that's the specific SKU covered here. During our automated check, this listing briefly displayed a "cannot be shipped to your selected delivery location" banner rather than a normal buy box; we've seen this exact false-negative pattern before on non-US-routed research sessions, so we cross-verified the listing independently through a third-party Amazon price-history tracker and Amazon's own "bought in past month" activity signal, both of which point to a genuinely active, frequently purchased US listing rather than a dead one.
The 9864 is Wahl's do-it-all grooming kit built around a wide T-blade for beard and mustache work, paired with a precision detailer head for cleanup and detail lines, a rotary ear-and-nose trimmer head kept physically separate from the beard blade for hygiene, and a dual-foil shaver head for close shaves. It comes with 10 guide combs total: 8 T-blade combs running from 1/16 inch to 1/2 inch, plus 2 adjustable 10-position combs. Wahl's Lithium Ion 2.0+ battery is rated for about 3.5 hours of continuous runtime and is built to hold charge over long storage gaps, and the unit runs on worldwide voltage (110V/220V/dual voltage), which matters if you travel internationally.
This is the most affordable of the five kits here relative to what's included, which is the main reason it earns a spot: you get a beard trimmer, a separate shaver head, and an ear/nose trimmer in one box rather than paying for those as add-ons.
