How to choose between them

Both run on Milwaukee M18 batteries, so your existing packs and chargers fit either tool.
Evidence boundary: 3 spec rows are published by only one maker in the table below; unstated figures are treated as unknown rather than assumed.

From the published figures only; no testing. Rated figures from different makers are not measured the same way.

4 verified spec differences across 7 specs published for both models (3 specs are listed by only one maker). Stated from the published figures only; no testing.

Same tool category: both are chargers.
Matching published specs: Warranty: 5 Year Limited Warranty; Charging mode: Sequential; Dimensions: 6.1 x 3.42 x 7.95 in.

Published by only one maker (data gaps)

Charge time (maker's figure): 48-59-1812 lists compact batteries in 30 minutes and extended capacity batteries in 60 minutes; not listed on 48-59-1808's US maker page.
Charging ports: 48-59-1812 lists 2; not listed on 48-59-1808's US maker page.
Charge indicator: 48-59-1808 lists indicates 80% charge; not listed on 48-59-1812's US maker page.

A missing value means the manufacturer page does not publish that figure; we never guess or count an unstated spec as a verified difference.
