I thought that the AC70 would charge the B80 but nothing seems to happen.
I have connected the B80 to the AC70 with the correct cable and the AC70 is plugged into the mains. Both units are turned on, what am I doing wrong?
I have had them connected like that for around 3 hours and the B80 is still only showing 3 lights, which is how it started.
Advice appreciated
Ah, since posting this I realise that the B80 can’t be charged directly from the AC70! 
Hi @Chyperie, Thank you for the update.
Yes, the B80 can be charged together with the AC60 when connected to it.
Besides that, you can also charge the B80 using a 12V-28V solar panel. It also supports charging via a 12V car charger and an AC adapter.
Hi, thanks for the helpful clarification!
That’s great to know the B80 can charge simultaneously while connected to the AC60 really useful for keeping things powered without extra steps. The flexibility with charging options (solar, car charger, or AC adapter) makes it even more practical, especially for outdoor use or backup situations.
Appreciate you confirming this
