Ze Frias Posted June 27, 2015 Report Share Posted June 27, 2015 Are you thinking about using solar cells to charge your bag's battery? Quote Link to comment Share on other sites More sharing options...
David Marien Posted June 29, 2015 Report Share Posted June 29, 2015 If I am not mistaken, E = Q x V The USB outputs let me guess this is 10 000 mAh over 5 Volts so: E = (10000 x 5) /1000 E = 50 Wh (theoretical maximum) That's around 30% less than a regular NP1 but it could be useful as emergency power. You will still need to regulate the output up to 12V, which will bear a cost in efficiency. I look forward to see what you intend to do with this.

dfisk Posted June 30, 2015 Report Share Posted June 30, 2015 I've done extensive research into using solar to charge NP batteries in a bag. You'd need a massive solar panel in direct sunlight for it to kind of work. A small little solar cell like that is only good for charging your cell phone, and even then you need direct sunlight, which in vegas isn't really a problem.

Andrew From Deity Posted August 22, 2015 Report Share Posted August 22, 2015 (edited) I bought a $5- 5v USB to 12v DC cable off eBay and I use it to run my PSC Promix-3. I run it off a very simular type setup. 8,000mah 5v 2A USB battery = 12v 750mA Edited August 22, 2015 by Drew3296 Quote Link to comment Share on other sites More sharing options...
