A: The TORNADO90000 is produced in two models with different
input voltages: 100-120V and 200-240V. Please check the label
on the back of the product to confirm the input voltage. Do not
connect TORNADO90000 with 100-130V input voltage to a 220V
power supply, which will cause damage and even fire.

We recommend that the current value should not be greater than
20% of the battery capacity value. For example, for a 100Ah battery,
we recommend that the current is not greater than 20A.

battery is fully charged?

the risk of overcharging. If you still leave the battery connected,
then the charger will keep monitoring the battery status and will
automatically start charging when the battery voltage falls below its
target threshold.

simultaneously?
A: Yes. Please correctly connect these batteries in series or parallel
before charging. If you have questions about the connection, you
