The buying question

Do you need concurrent charging or a larger M18 queue, and how will you prioritize packs?

Concurrent charging with mixed-platform bays versus more M18 waiting positions.

Quick verdict

When to skip: You need six M18 packs charging simultaneously.
When the recommendation changes
  • Your pack collection changes between M12 and M18.
  • Keeping every M18 pack inserted matters more than concurrent charging.

The differences that matter

Battery Bay Concurrency

Milwaukee 48-59-1807 M18 & M12 Rapid Charge Station

Three M18 bays plus three M12 bays; up to three packs charge simultaneously.[1]

Milwaukee 48-59-1806 M18 Six Pack Sequential Charger

Six M18 bays; packs charge one at a time.[2, 4]

What this changes: Count your packs by platform: six M18 packs fit the Six Pack, while the station trades three M18 waiting positions for M12 support and concurrent charging.[1, 2, 4]

The better fit depends on your priorities

Priority Queue Workflow

Milwaukee 48-59-1807 M18 & M12 Rapid Charge Station

Three M12/M18 pairs: the first pack loaded in each pair charges before its partner.[3]

Milwaukee 48-59-1806 M18 Six Pack Sequential Charger

Counter-clockwise charging order; the skip button advances to the next pack.[4]

What this changes: Load urgent packs first in each station pair. For an M18-only queue you want to advance manually, the Six Pack provides the documented skip control.[3, 4]

The better fit depends on your priorities

An M18-only collection needing concurrent charging

Best fit: Milwaukee 48-59-1807 M18 & M12 Rapid Charge Station

Based on listed features, not comparative testing.

M12 ownership is not required to benefit from the station’s three charging channels; the compromise is fewer M18 positions.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Pay for the loading pattern you will use, rather than bay count alone.

There is insufficient price history for a purchase-timing recommendation.

Limitations

  • Neither was hands-on tested for this comparison. Pack-specific charge times, heat, lifespan and reliability are not ranked.
  • Use these US models on 120 V AC only. Keep charging dry and well ventilated, with vents clear; follow each manual’s charging-temperature limits. Unplug before maintenance.

Questions shoppers ask

How should I load a mixed batch on the station?

Think in pairs, not a single six-pack line: put the more urgent battery into each M12/M18 pair first. Its partner waits for it to finish; the other pairs have their own order.

Can the station hold six M18 packs if I leave its M12 sockets unused?

No. Unused M12 sockets do not become M18 bays. A six-M18 batch needs the Six Pack’s layout, or pack swapping on the station.
