+1 for Anker products.

I EDC an Anker Astro E1...it’s 6700 mAh. I haven’t checked the weight, but I’m guessing carrying two of them would still weigh less than a 10000 mAh, and they are small enough to fit well in backpacking gear.

Well made product that I have been very happy with.

I keep a Nomad keychain charging cord in the included pouch with the Anker...it doesn’t have much reach, but I always have the cable to charge with.

Not as cool as having a solar rig with you...
