The Battery Adapter Pack for the Spotnails 18V Cordless Compressor allows compatible DeWalt 18V XR or Milwaukee M18 slide batteries to power the Spotnails Compact Silent 18V Cordless Air Compressor – 6L.

Select the adapter variant that matches the battery platform you already use. Each pack contains two matching adapters, allowing both of the compressor’s native Makita-format battery bays to accept batteries from the selected platform without purchasing another complete battery and charger system.

The compressor can operate with one battery or two. Use one adapter for single-battery operation, keeping the second ready as a spare, or use both supplied adapters to fit two compatible batteries for extended motor runtime.

Select Your Battery Platform

Choose DeWalt 18V XR for compatible DeWalt slide batteries or Milwaukee M18 for compatible Milwaukee slide batteries. Makita 18V LXT batteries connect directly to the compressor and do not require an adapter.

Key Benefits

  • Allows an existing professional battery platform to power the Spotnails 18V cordless compressor.
  • Available for compatible DeWalt 18V XR and Milwaukee M18 batteries.
  • Simple slide-on fit between the battery and compressor battery bay.
  • Supplied as a cost-effective pack of two matching adapters.
  • Provides both adapters required for two-battery compressor operation.
  • No wiring or modification to the compressor is required.
  • Helps avoid purchasing a separate Makita battery and charger system.
  • Designed specifically for the Spotnails Compact Silent 18V Cordless Compressor – 6L.

Choose the Correct Adapter

Adapter Variant Compatible Battery Platform
DeWalt 18V XR Compatible DeWalt 18V XR slide batteries; excludes the DeWalt 5Ah Powerstack battery.
Milwaukee M18 Compatible Milwaukee M18 slide batteries; not suitable for Milwaukee M12 batteries.

Check Your Selection Carefully

The two variants are not interchangeable. Select the adapter matching the exact battery platform you intend to use. The DeWalt 5Ah Powerstack battery is specifically stated as incompatible with the DeWalt adapter.

Why Are Two Adapters Supplied?

  • Using one DeWalt or Milwaukee battery: use one adapter and keep the second available as a spare.
  • Using two DeWalt or Milwaukee batteries: the pack contains both matching adapters required.
  • Using Makita 18V LXT batteries: no adapter is required.

Fitting two batteries extends the compressor’s available motor runtime but does not increase its maximum pressure. When using two batteries, use two compatible batteries from the same platform with matching capacity and a similar state of charge.

What Is Included?

  • 2 × matching battery adapters in the selected variant.

Please note: Each pack contains two adapters for the same selected battery platform. It is not a mixed DeWalt and Milwaukee pack. The Spotnails compressor, batteries and battery charger are not included.

How to Fit and Use the Adapter

  1. Confirm that the compressor is switched off and positioned securely.
  2. Check that the adapter variant matches the battery platform being used.
  3. Inspect the battery, adapter, contacts and compressor battery bay for damage or contamination.
  4. Slide the adapter into one compressor battery bay until it locks securely.
  5. Fit the compatible battery to the adapter and confirm that it is fully engaged.
  6. If using two batteries, repeat the process using the second matching adapter supplied in the pack and another compatible battery.
  7. Operate the compressor in accordance with its supplied instructions.
  8. After use, switch the compressor off before removing the battery and adapter.
  9. Remove the battery from the adapter and charge it only with the battery manufacturer’s approved charger.

  • Do not use damaged, wet, excessively hot or contaminated batteries or adapters.
  • The adapter is for powering the compressor only; never attempt to charge a battery through it.

  • Remove batteries before inspection, cleaning, transport or storage.
  • Stop using the adapter immediately if it becomes unusually hot, loose or damaged.

Each order quantity of one supplies one pack containing two matching adapters for the selected battery platform. Battery fit and runtime depend on the exact battery model, capacity, age, condition and state of charge. Brand names are used only to identify battery-platform compatibility. Batteries, chargers and the compressor are sold separately.
