    I am thinking of getting a battery powered charger for my Nexus 7 since I will taking it for all day outdoor use at an event later this summer. I saw quite a few listed but they had varying values of mah. How do I know what size I should consider?

    The efficiency of such a charger is about 60%.
    So, for to give your Nexus a full charge the charger's battery shouldn't be less than 1.7x of the capacity of your Nexus' battery.

    I'd look for an Anker Astro3 10000mAh powerbank.

    I'll second that. I bought one of these and it's great for the N7 (and other devices) --

    Amazon.com: Anker

    Anker is good. Highly recommended.

    Don't forget that besides capacity, you will probably want to consider output current when making a decision. Higher outputs can charge faster and may allow you to charge larger devices.

    You want to absolutely make sure whatever you get states it works for the nexus 7.

    Many of them are not able to charge the tablet

    IE. make sure it has a 2A output. That's what the N7 charger outputs.

    I second Anker products though. I have had the older 8400 mAh power bank for over a year and still works great. The build quality is rock solid.
