Ideal for tools with 18 V dual battery system: both battery packs are quickly and simultaneously fully charged again. Cross-voltage class: Suitable for all battery packs in the 10.8 V, 14.4 V and 18 V classes (exception: BP-XS for CXS/TXS 10.8 V). Always informed: Separate LED display for showing the charging status on both charging bays. Neatly stowed away: Cable storage on the housing and the wall-mounting device keep things tidy. All-round protection. Of course, the DUO quick charger is also fully protected by Festool Service. The TCL 6 DUO quick charger offers power for two: two battery packs are charged simultaneously via the two slots. This is particularly practical for all tools with 2x 18 V dual battery systems. Because when battery packs are discharged at the same time, they should be fully charged again as quickly as possible. Suitable for almost all battery packs of the 10.8 V, 14.4 V and 18 V class: no matter whether Li-HighPower Compact battery packs, the handy Ergopacks or all AIRSTREAM variants (exception: BP-XS for CXS/TXS 10.8 V). In addition, there is no need to search for a second socket for an additional charger - very practical for use on the construction site or in the vehicle. So you can continue working quickly and with full energy. And for a complete overview, the two separate LED displays provide information about the current charging status at both charging sockets at any time....
