Great addition at my EB3A and PV 120

Work perfectly whit an actual EB3A when is synchronize. The PV 120 watts charge perfectly during a sunny day. Other way to charge, using a cigarette lighter port of EB3A connected to DC input port of B80 when you charging your EB3A with an AC input port connected.

So Far So Good

I have used the B80 to recharge my EB3A, and to power a DC cooler via the car adapter 12v plug. I also purchased the 200 watt AC power brick earlier so I can charge it direct from AC or generator using the solar input plug. The plan is to buy another one and eventually an AC-60 to complete the combo. I bought this one specifically for its' water resistance and it will be my travel/camping choice. I also have all the accessories required to charge it in every way possible including car and solar.

It’s solid or well built. It can be used as a power bank for my EB55 and I am yet to see how well it can expand the power of an AC180 as well. Good back for off grid adventures and power outages.

B80 Expansion Battery

I ordered and received my B80 battery a couple of months ago and have been very happy with it. I love the rugged design and solid build of this unit. The buttons feel great when I use them. I have used the B80 standalone for DC loads, in Power Bank mode with an EB3A, and as an expansion battery for my AC60, all without issue. The B80 and AC60 were used for an extended road trip to keep a compressor fridge running in my vehicle 7x24 for 10+ days, including several in very hot Florida weather...again, these units worked flawlessly. I appreciate that the B80 has its own solar input and MPPT controller; I can charge it from my PV200 panel when it is standalone, or I can "double up" when the B80 is connected to the AC60 (which has another 200W of solar).

Note that if you plan on using the B80 without an AC60, you will have to purchase a seperate T200S adapter for AC charging. I have been using this with the B80, also with great success.
