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
RYOBI ONE+ 18V Lithium-Ion Starter High Performance Kit with 2.0 Ah Battery, 4.0 Ah Battery, and Charger
Pros
- Includes two batteries — a compact 2.0Ah pack and a higher-capacity 4.0Ah pack — plus a charger, all genuine Ryobi
- Two different pack sizes cover both lightweight/compact use and longer-runtime use from one purchase
- Good value for a two-battery-plus-charger bundle at under $100
Cons
- Currently showing low stock on Amazon
- Because it bundles two different-capacity batteries, we don't collapse that into one capacity number — check the listing for the exact 2.0Ah/4.0Ah split
- We haven't run our own runtime tests; capacities are Ryobi's stated ratings
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.
RYOBI ONE+ 18V Lithium-Ion Starter High Performance Kit with 2.0 Ah Battery, 4.0 Ah Battery, and Charger
A genuine Ryobi kit that pairs a compact 2.0Ah pack with a higher-capacity 4.0Ah pack and one charger — solid value for ONE+ owners who want both a light pack and a runtime pack.
