This item is the battery controller used with the model 7090. The primary difference is that it requires the new AC power supply when using the Aeroneb GO on AC wall power. You can use ANY of the Aeroneb GO OnQ micropumps with this Battery controller. The most important thing to know is that this Battery Controller has TWO wire connections on the front - one for the DC cable that goes to the micropump and one for the AC power supply.
This Battery Controller works on ALL Aeroneb GO HandSets
