20,000mAh of power keep you and your gear going, and going - and going. Add 1000% more battery life to an iPhone, 600% to your large-capacity phone (like a Galaxy S4), or 130-300% to your tablet (depending on its battery capacity) - all away from an outlet. What's more, the added energy efficiency gives you 10% more usable power than the previous generation and many standard alternatives.

5 out of 5 eggsneed a really good spare battery?

Pros: This is my second Anker 2nd Gen astro pro2...I loved the first one and found it super handy. It's good for a full charge from near 0% battery on a shield tablet while you watch video leaving the anker with approx 30% left after. If your playing games though its only good for one fill from the increased power consumption. Anyways my wife and I wanted more juice on the go so we got a second battery. So far its just as good as the first. Now we should be set for that plane flight to Australia!

Cons: making sure the charger recognizes a device at plug in....make sure your lcd screen is lit when you plug in your usb port or the device may not charge ;)

Other Thoughts: would love to see a double (40k) or even triple (60k) capacity unit.

5 out of 5 eggsCharges everything you need and then some.

Pros: It actually fits in my pocket, while being thin enough to get my keys or phone in there as well. feels kinda awkward though. See other thoughts.

Cons: Takes all day to charge, but that's to be expected when you're carrying around enough power to jump start a few cars.

Other Thoughts: I bought this thing off Newegg during a Sale. Greatest buy and I normally get everything I order within 2-4 days with free shipping. It came in time before the camping trip. Two of my friends and I got into Vaping and we wanted to use our vapes while out adventuring. Anyway with the DC output we were able to recharge our 18650 batteries a few times (using a charger with a detachable DC input port), our phones and iPods. When I got home It still had 6% battery life left. Considering when it came in the mail it only had 83% power and I took it with me like that. It did pretty well.

This thing actually fits in my pocket. Granted I wear those Carpenter jeans with the large pockets and several other side pockets on them. They still fit. I was able to charge my smaller 800Mah vape through one of the USB ports and my iPod as we walked through the mountains. Its nice knowing if something starts dying I can hook up 3 different devices at once to charge them.

However, I think hooking up 2 or more devices at a time drains the battery faster than charging each device individually. I've been too lazy to do a test though.

It just feels like it wastes a bit more power when its charging several things at a time. It could just be me though.
