Hello,
I am going on a 7 day backpacking trip and would like to use my Ambit 3 peak to track the trip. I figure that I will nee to recharge it 2-3 times during the trip. Does anyone know what capacity external battery I would need to accomplish this? Anyone have recommendations on battery backs they like?
Thank you,
Aug 4, 2015 at 6:10 pm #2219043It must recharge with USB?
How many mAH is the battery?
Multiply by 3 since you want to recharge 3 times, and multiple by 2 for inefficiency and get a battery pack with greater than that capacity
If your battery is 500 mAH, for example, you want a battery pack that has at least a 3000 mAH battery.
I got an Anker from amazon.com that's worked okay. Several other people same.

I haven't used the GPS on my Ambit 3 yet, is that the reason for the limited battery life you are estimating?

I haven't been able to find the specs for the battery size in the Ambit 3. I found that the Ambit 2 has a 480 mah so I imagine the 3 would be in the same neighborhood. I am doing an off trail Wind River trip and would like to keep GPS on at the lowest battery consumption level to track the route we take. I also like having all the other information you get by hiking with GPS activated.
I am not sure how much battery drain I will encounter but I want to be sure I get the whole trip. It seems like something around 3000 mah would be sufficient.

Aug 4, 2015 at 7:07 pm #2219059480, 500, good guess? : )
3200 mAh for $12 if you have prime

I thought you knew the battery size. Definitely a good guess. Thanks for the link.
Aug 4, 2015 at 7:17 pm #2219064Once you get one if you don't mind I would love to know how it works out for you James.
I'm not in immediate need but I have an Ambit 3 and like you for use on multiple day treks am searching for a good battery solution.cheers

Sure thing. I will let you know my thoughts when I get back from the trip.
