That is everything except for the internal battery which it needs. Once you add a battery to it (not the one in the pine, the solar power bank needs its own), as long as you consider that it may take that unit 2 or 3 days to fully charge between uses... it would probably be fine. However, I really, really, REALLY don't like those sorts of chargers... as lithium batteries do NOT like getting hot (it's one of the three quickest ways to kill/severely reduce the service life of a lithium battery). Plus the solar panels are pretty crappy, and don't charge them that fast at all... they're really there as a selling point and only good for cosmetic appearances... they might as well have just painted them on for all the good they really are. 

In all honesty, if you want the more portable route, you'd be better off with a 10,000mah-ish power bank (especially  if it supports passthrough charging so you can use it and charge it at the same time) ... I personally can't go past the Xiaomi powerbanks for quality and performance... and a folding solar panel like this (just an example... that one probably isn't the cheapest, but is a good brand and should be able to power the pine64+LCD and charge the pine64s battery in most conditions without any dramas). Then you'd also be able to use that setup with anything else you have that needs USB power / charging when you're not using it for the pine64 tablet combo. 

The only other option is to get some 6v (preferable tempered glass for longevity... the normal epoxy ones will probably only last you 6 months before the epoxy crazes) solar panels, 18650 batteries and holders, a solar charge controller, a 5v boost module, and protection circuitry for the 18650 batteries, but that will probably cost more than an off the shelf combo to be honest, especially if you don't get it right the first time.  But if you want to do it to learn, then great, all the better! Wink

iv'e been working on this for several weeks now, ill upload pics later, i have a 7mm thick 4000mah li-on battery with the thermister trick, my pine seems to charge too slow, is there any way to boost charging time
my battery seems to be lasting around 6 hours on idle with android 5.5 and the thermister trick, it takes about 6 hours to charge on ac this doesent seem right, will it charge faster with a battery that has a thermister, the pine is also telling me its a 2850mah battery and its ment to be 4000mah
