You can use USB 5v  charger , but there is danger of exlosion, as the output of these devices is not tightly regulated to 5v. If you carefully measure and observe the output, you can see it going to 6v or more. So, I think you could use a zener-transistor circuit like this for your purpose.Adapting to 5v solar panel is 








































super easy . Just use the  panel in place of the Adapter USB wires ! 
This is too low cot circuit and the usability  is huge 

 In case you are trip to village where no power , make a tincan  box fitt the solar and circuit , youhave powerbank on the go !

SpaceX ElonMask , is building up inter-globe-travel : Newyork to Mumbai in 30Minutes

Elon Musk predicts rockets will one day have the capacity to fly individuals from New York to Shanghai in only 39 minutes. Musk's organization, SpaceX, is building up a colossal shuttle to colonize Mars. It could likewise be utilized substantially nearer to home. Talking at a space meeting in Australia on Friday, Musk said the organization had investigated applying the innovation to zooming individuals to better places on Earth in madly quick circumstances. "The outcomes are very intriguing," he said as a video demonstrated a recreation of individuals boarding a rocket in New York that launched into space and afterward returned to arrive in Shanghai. Related: Elon Musk is expecting to arrive spaceships on Mars in 2022 "The  most interesting thing about going to space is there's no contact, so once you're out of the air ... it'll be smooth as silk, there's no climate," Musk said.

you said Joule Thief?

you said Joule Thief?  you said Joule Thief?  It’s a little wisp of a circuit that allows you to drive aPOWER  LED from a low voltage. Normally, if you want to light up a blue or white LED you need to provide it with 3 – 3.5 V, like from a 3 V lithium coin cell. But the magic of JT is  a 1.5 V battery like a AA cell simply will work.  Easy make  Joule Thief,  works like a charm. Not only does it work with a brand new battery, but it works until the battery is nearly dead– down to 0.3 V.  That’s well below the point where your other toys will tell you the battery is dead, so it can steal every last joule of energy from the battery (hence the name). how about a cellphone charger , yes it is doable , we are here to give you  a usable tested diagram . get  the ring toroid from a OLD smps of pc !
