I went with this one:

It can charge devices and the internal batteries at the same time.

This one charges mine and my wifes phone all day long walking around. Its been fantastic. Takes all night to charge back up though.

We are brining a portable charger like this

I ordered a bunch of stuff for this year. I went a little amazon crazy.

I stubbed my toe on a tent stake last year so I ordered these glow in the dark tent stakes.

I figured this blow up couch would be a cool addition to our campsite.

I got one of these battery powered fans for my tent.

I ordered a few of these batter powered led lights in different colors for decoration.

I ordered like 4 of these portable fans for our camping group to clip onto their camel packs for the daytime heat.

I ordered this portable battery pack to keep my phone charged.

I ordered a 300 pack of glowsticks 100 for each day.

I ordered these light shooter things. They are fun to play with in the camping grounds.

I ordered one of these anti chafe sticks for my fat legs. It's truly a life saver.

Also I ordered The Watterpuff for obvious reasons.

I picked up this one:

Bit hefty, but long warranty and great charging capacity.
