Yes — if you own a Makita 40V max XGT charger, the company sells an official adapter that lets it charge 18V LXT batteries. That adapter is the ADP10, and unlike the adapter stories on this site for DeWalt and Milwaukee, this one is a genuine, purpose-built bridge between two different voltage platforms.
Makita’s own page for the 18V LXT Adapter for XGT Chargers says the ADP10 “adapts 40V max XGT Charger (sold separately) to charge 18V LXT Batteries (sold separately).” That wording matters: this is not a third-party workaround or a hinted-at future accessory. It is a real, official cross-voltage-platform charging bridge, sold by Makita, for the specific job of letting one XGT charger service LXT packs.
The charging speeds Makita publishes are straightforward, with one detail worth reading exactly as written. The ADP10 “Charges an 18V LXT Lithium-Ion 6.0Ah battery in only 40 minutes” and also “an 18V LXT Lithium-Ion 5.0Ah battery in only 40 minutes.” Makita lists the same 40-minute figure for both the 5.0Ah and 6.0Ah packs, so this is reported as published rather than second-guessed. For smaller LXT batteries, Makita says the adapter “Charges an 18V LXT Compact Lithium-Ion 2.0Ah battery in only 24 minutes.”
Those times assume you are pairing the adapter with an XGT Rapid Charger. Makita describes that charger as having “a digital display [that] indicates battery charge level (-80%, +80%, 100%)” and a “dual-fan design” that circulates air to cool the battery and circuit board for faster charging. The company also notes that “digital communication within XGT actively monitors and protects against overload, over-discharge and overheating,” and the ADP10 itself carries a “3-year limited warranty.”
Now for the limits, because this is a charging-only story. The ADP10 does not let an 18V LXT battery power a 40V max XGT tool, and it does not let an XGT battery power an 18V LXT tool. No Makita page claims otherwise, and this guide is not going to imply it. The adapter is a charger adapter, full stop. If you are hoping for one battery family to run the other, Makita does not sell that capability.
There is a related, separate accessory worth knowing about if you want to get more use out of LXT batteries off the tool. Makita’s 18V LXT Power Source “turn[s] your 18V LXT Battery into a charging port,” with “a USB port for use with portable electronic devices.” It is “Compatible with Makita 18V LXT Batteries, BL1820B, BL1830B, BL1840B, BL1850B, BL1860B.” Makita also says it “Provides up to 29 hours of run time when used with Makita heated jackets and blanket using Makita 18V LXT battery, BL1850B,” though that 29-hour figure is specific to heated jackets and blankets, not a general claim about USB runtime.
That power source is not an adapter between LXT and XGT; it is simply another way to squeeze utility from an LXT pack. It does not change the broader takeaway: Makita’s cross-platform effort is centered on the charger, not on swapping batteries between tools.
So here is the practical bottom line. If you already own both LXT and XGT tools and you are tired of maintaining two chargers, the ADP10 is a genuine, official, Makita-endorsed way to simplify down to one XGT charger plus this one small adapter piece. It is the most direct cross-platform bridge covered in any of this site’s adapter guides — ahead of RYOBI’s separate dual-platform charger approach, and matched only by Bosch’s native tri-voltage charger that handles multiple voltages without an adapter at all. Just keep the boundary clear: charging only, not tool-level or battery-level interchangeability. If that matches what you actually need, the ADP10 is the clearest answer on the market.
