How to calculate the time of operation of the central panel from an external battery


Divide the capacity of the external battery by the power consumption of the central panel.

Power consumption of the central panel depends mostly on active communication modules. The average input current values in the table ​​are valid for 12 V⎓ power supply and when up to 2 devices are connected to the hub or range extender.

Central panel / range extender Active communication modules Average input current
Hub GSM 42 mA
Ethernet 80 mA
GSM+Ethernet 90 mA
Hub Plus GSM 35 mA
Ethernet 72 mA
GSM+Ethernet 93 mA
Wi-Fi 20 mA
Wi-Fi+GSM 42 mA
Wi-Fi+Ethernet 80 mA
Wi-Fi+GSM+Ethernet 96 mA
Hub 2 (2G) GSM 33 mA
Ethernet 80 mA
GSM+Ethernet 86 mA
Hub 2 (4G) GSM 40 mA
Ethernet 78 mA
GSM+Ethernet 90 mA
Hub 2 Plus GSM 60 mA
Ethernet 90 mA
GSM+Ethernet 115 mA
Wi-Fi 45 mA
Wi-Fi+GSM 63 mA
Wi-Fi+Ethernet 95 mA
Wi-Fi+GSM+Ethernet 125 mA
Hub Hybrid (2G)* GSM 54 mA
Ethernet 85 mA
GSM+Ethernet 95 mA
Hub Hybrid (4G)* GSM 49 mA
Ethernet 85 mA
GSM+Ethernet 96 mA
ReX 20 mA
ReX 2 without Ethernet 20 mA
with Ethernet 75 mA

*Average current when no devices are connected to Hub Hybrid.

Note that every additional device connected to the hub may increase the hub power consumption.

For instance, when connected to a 40Ah battery, Hub 2 (2G) — with active GSM module only — will operate approximately 1200 hours (40Ah / 0.033A).
