Portable power supply?

[rawfa]

Hi guys,

Now that I´ve got the H4N along with the NTG3 I´m looking for some good options regarding portable power supply for the H4N (I´ve heard its´ phantom power drains it pretty fast). I´ve checked the duracell usb power supply that isn´t the most powerful (1150 mAh) but it´s pretty small. Do you think this would be enough to get me through one day of shooting? What other small alternatives are there?

Sure there are options. Much depends on exactly what "one day of shooting" means? Do you have access to mains power? Do you have an equipment cart? Do you need something you can clip to your belt? Do you need something that attaches to the recorder that you are holding in your hand? Do you need a solution where you can get a quick replenishment by using primary (throw-away) cells? Or do you want to use secondary (rechargeable) batteries? etc. etc....

I've got a tascam dr-100 mk2 with a ntg-3 and some sennheiser 380 hd pros and have the exact same problem. Even with decent rechargable energizer 2450ma AA's i'm getting about 20min of battery, it's bloody useless. Either way I'm looking for something reliable as well, just found this thing http://www.amazon.com/Energizer-XP18000-Universal-External-Netbooks/dp/B002K8M9HC but no idea if it actually works well at all.

Sorry, I should have been more specific. By a days´shoot I´m talking about an 8 hour shoot using phantom power and recording at maximum quality.
