Hi Bill
I forgot to mention in previous reply, that if your op uses VNC for monitor on a cell or tablet your
pi may not draw more than 2A while in use. I am not sure I could see the screen on my cells maybe
on a tablet.

Hi Marty,
I looked at customer "questions" section and the manufacturer states 5V@2 amps and 12V@3 amps. I removed those batteries from my "shopping cart" since they won't actually meet my use needs. At the moment I am running 12V sealed lead-acid batteries (SLAB) at just over 7 Amp-hours. They are holding up well but are reaching end of life. Some of my gear draws up to 7 amps in transmit. If I only wanted them for QRP operation they would be suitable. Maybe I will buy *one* for that purpose. However, when I buy more suitable (to me) batteries those will certainly handle a QRP rig at the park. I run up to about fifty watts when I feel evil :) Less than one watt sometimes too so maybe there is some hope for me.
I will look at other offerings from this and other manufacturers.

Hi Bill
I looked at the pictures on the left side that shows the different views. The
second one down showing the front with the switch and USB and 12V
input/output the USB shows 5v/2A (Max).
My pi is housed with a monitor and I know it says 5.1V/3A and it does show
low voltage warning, because I used a Buck Converter that had screw terminals
for the connections and had to remove the connectors and solder the wires
in/out to overcome the voltage loss., Maybe if you pi in run headless it
is ok with 2A at 12V, good luck.
Nice looking battery if it works good.

Hi,
I put two of them in my 'cart'. I didn't notice anything about a 2 amp limit on the 5 volts. And nothing on the 12 volts either. Where did i fail to look?

Hi
I noticed the 5V is only rated at 2A, have you noticed any problem with the pi which needs 3A
I believe?

Roy, the battery I use is this:

which is nice in that it also provides a 5v connection for the RPi in addition to the 12v for the rig. Seems to run all day.
