Works great with the goggles, provides good amount of fly time from full charge and charges quickly. SD card reader is very convenient as well!

Honestly this card reader, battery pack was the decisive factor for purchasing a set of HDZero goggles and it work's really well! The contoured clips for the strap, the quick start barrel plug and the illuminated charging status lights made it a "no brainer", best choice imo.

The sd card reader is truly a selling point but i have a samsung, and im just not going to pop open the battery compartment to read an sd. Genuinely seeing others with an adapter and a portable charger makes me feel like i shouldve gone that route.
