Select the charger that matches your model. Delta 2026 and Delta 2027 share the EU-plug charger: 110–220 V input and listed 72 V / 10 A output. Its output connector is not specified in the supplied comparison sheet and requires confirmation.
Delta S uses a different 84 V / 7 A charger: US input plug, Liu Shi M25-2+1+5-40A straight output connector, CAN communication and 1.2 m cable. The two versions are not interchangeable. Shared image for reference.
