The TCL 6 DUO Rapid Charger supplies enough power to charge two battery packs at the same time. This is beneficial for all tools with a 2 x 18 V dual battery system. Being able to charge two battery packs at the same time is not only convenient, but reduces downtime as both batteries are ready at the same time . Suitable for virtually all battery packs from the 10.8 V, 14.4 V and 18 V classes, whether Li-HighPower Compact battery packs, the handy Ergo packs or all AIRSTREAM variants (with the exception of BP-XS for CXS/TXS 10.8 V). In addition, you no longer need to look for another outlet for another charger – which is extremely practical for applications on job sites. This means that you can quickly get back to work with full power. Two separate LED indicators give you a complete overview of the current charge status for each of the batteries.
