Garmin 500 Battery Extender

I have a Garmin 500 and I want something that will allow me to extend the battery beyond the 8 - 14 hour internal battery.  Any suggestions?

Dan:
There are all sorts of small portable large capacity devices on Amazon.
I use these for back up on night rides and longer rides. 
You charge them up at home and use them as needed. 
Make sure the device you select has a method of connecting to the MINI USB on the Garmin.
Just figure a way to mount the back up somewhere on you ot the bike with a suitable length USB cable.

Dan –
 
I have a Garmin Edge 500, and here’s my setup.  If your Garmin’s software is different from mine you might get different results, but this gives me a runtime of well over 24 hours (longest runtime to date was around 28 hours with over 50% battery still remaining), and as an unexpected bonus the backlight stays on the whole time!

Powerbank, 3350 mAh; $11.99 from Amazon:  https://www.amazon.com/Smallest-Jackery-3350mAh-Portable-Charger/dp/B00L9F95RO/ref=sr_1_5?s=wireless&ie=UTF8&qid=1513869403&sr=1-5&keywords=jackery
 
You might already have a powerbank lying around, any size should work.  And I use a 6’ USB cable so that my powerbank can sit in my seatbag, but a shorter one might work, depending on your bike setup.  Also, be sure to use an OTG cable, not just a mini-USB adapter - the adapter cable will probably put your Garmin into recharge mode and stop it from recording; the OTG cable lets it record and charge at the same time.
 
Good luck!
