Pros & Cons
Milwaukee 48-59-1808 M12 and M18 12V/18V Lithium-Ion Multi-Voltage Rapid Battery Charger
Pros
- Charges both M12 and M18 REDLITHIUM packs from one charger, useful if you own tools on both platforms
- Genuine Milwaukee OEM part, not a third-party clone
- Priced under $60, cheaper than buying a dedicated charger for each platform
- Compact footprint for a toolbox or job box
Cons
- Listed as non-retail/bulk packaging — no retail box or included manual
- Manufacturer listing doesn't state charge time or amperage, so we can't quote a speed
- Amazon listing shows check-availability status rather than guaranteed in-stock
Milwaukee 48-59-1850 M18 XC 5.0 Starter Kit
Pros
- Bundles a genuine Milwaukee M18 XC 5.0Ah battery with a charger in one kit
- 5.0Ah capacity gives meaningfully more runtime than Milwaukee's compact 2.0Ah/3.0Ah packs
- Genuine Milwaukee OEM, not a third-party bundle
- Good starter option if you're buying into M18 for the first time or need a spare battery-and-charger set
Cons
- Only includes one battery — no second pack for hot-swapping
- 5.0Ah packs are larger and heavier than compact packs, which can make lighter tools feel nose-heavy
- We haven't run a runtime test ourselves; 5.0Ah is the manufacturer's stated capacity
Our Verdicts
Milwaukee 48-59-1808 M12 and M18 12V/18V Lithium-Ion Multi-Voltage Rapid Battery Charger
If you run both M12 and M18 tools, one charger that handles both packs is a real convenience — this is a genuine Milwaukee part at a fair price, though stock availability varies.
Milwaukee 48-59-1850 M18 XC 5.0 Starter Kit
A solid way to add a genuine, higher-capacity M18 battery and charger in one purchase — good value if you need more runtime than a starter 2.0Ah kit provides.
