[App_rpt-users] USB Battery Bank that supports 'Pass Through Charging' and acts as a UPS for Allstar Nodes running on a Pi

[Ramesh Dhami]

Hi Folks:

Wonder if anyone has a lead on a USB Battery Bank that supports 
pass-through charging and does NOT interrupt the output voltage when 
there is loss of commercial power?

I'd like to use a battery bank on my remote node down in FL (renowned 
for electrical storms!), so keeping the Pi up during brown-outs and loss 
of commercial power is a big plus.

In case folks are interested - here is a link to a good article 
providing a review of various products:

Unfortunately, the leading contender, the product from RS Electronics 
(brings back memories of my "jollies" as an Apprentice heading up to 
Alum Rock in Birmingham ;) is not available in N. America.  There must 
be other equivalents out there.....

Anyone have a lead on such a product?

Thanks!
