I can confirm that, and add that the IKEA Solbana power bank does, too. It is a healthy 10000 mAh, but has only one USB output. It is discounted if you are a Family member, so the cheapest option for that capacity.

What's the use of the RED Button (in the IKEA Solbana)?

Interesting (non-member) pricing:
US $19.99!
Talks about rip-off! Or is it just after and before tax?

I assume you mean when disconnecting the input power it takes 1 second to restore power to the output? I didn't see anything that mentions that. I did see one review that said it can't generate output voltages above 12 volts when being charged, but that wouldn't be a problem for the rPi.
Seems this unit has a buck converter to generate voltages below 12 volts and a separate boost converter for voltages above 12 volts all selected by a pair of slide switches. I am guessing the boost converter is reused for the charging circuit so the higher voltages are not available when charging.

[]>> Rick,
From the Web page cited:
"3. When working as a UPS, connect the original power adapter to the item, and connect the item to the notebook. Upon power outage, the item will respond in less than one second"

[]>> Rick,
The unit has a 5V/2.1A USB outlet, which I would expect you to use for the RPi.

Thanks for the tip about the Solbana!
It comes with a USB to micro USB cable that makes it trivial to insert between a power adapter and a Pi.

Not sure what your point is. What your wrote has nothing to do with what I wrote.

I was unsure why you were mentioning the 12V output in connection with the RPi.

Why didn't you ask?

Because 12V doesn't appear on any of the other units under discussion, and hence didn't appear to be a mandatory requirement. Have you bought and tried anything yet?
-- Cheers, David Web: http://www.satsignal.eu
We've been discussing *this* unit and the details which are only documented in the comments by other users. What it will do or won't do in addition to powering an rPi is useful to me. I also like to actually understand things I buy, especially when there is no hope of ever getting support.

The critical stuff routers, switches etc.. is all set up for USP till the generator starts.. I need about 5 minutes max on that...
For me taking and getting another AC UPS v. a DC UPS ie: these USB battery things... seems over kill
AC UPS to power 3-4 AC to 5VDC USB adaptors.. the Pi's are all headless...
At this point since it actually may be less headache to the option I considered first... Since finding any of these USB batteries that will charge and ouput
5VDC at the same time is more hit or miss.Rick

To me it seems perfect kill once you consider *all* factors. A DC/DC UPS is hard to find and is questionable how well it would work. The AC UPS is a slam dunk giving much more capability allowing other things to be added in the future. The DC UPS will likely cost several sawbucks and the AC UPS is not much more and perhaps the same if bought on sale. Who knows how long the DC UPS will last and the AC UPS will last a decade, at least mine have. In fact, the one I depend on the most has been around for 15 years and still works. I see Microcenter has one for only $37.
Exactly.
