AZT and solar panels vs. battery bank alone
More last minute prep for AZT. Last Grand Canyon backpack trip I saw a guy with a Renogy 5W single panel (6oz?) on the top of his pack, which he said was enough to recharge his GPS, iphone, and some other USB appliance, while he was walking. He had it hooked to an Anker battery bank.
In an Amazon box, I have an Anker 15W solar lite multi-panel (12oz.) that allegedly has significantly better solar 'reception' when you are draping it over the top of the pack, compared to a single panel unit, which reportedly makes a big difference when you are walking and on the move, per illustrious Amazon reviewers. I have an Anker 15mah battery bank. I am using the iphone and Guthook as my only navigation device, apart from backup oldskool paper maps, so it is critical I am not running out of juice.
Anyone who has been using solar panels on the AZT care to share your experience with them?
Any battery bank only afficionados care to share your experience--are you getting caught short?
64K$ question??? If I am resupplying in town every 5 days, and my 15mah battery can recharge my iphone 6s+ 3+ times, and I have all the apps and bells and whistles turned off on Iphone to lessen energy demands, apart from Guthook, do I really need a 12 oz. solar panel--or any solar panel for that matter?
Thanks in advance.
