Adafruit Powerboosts in parallel, possible?

[CostasVav]

Hi,

I was wondering if I could connect a Powerboost 1000 Charger in parallel with a Powerboost 500 Basic. I know it is possible to hook two Basics in parallel to provide more power to a project.

Given only one circuit is charging, could this work? Would it need any extra circuitry, like diodes or anything?

Thanks!

Tested a Powerboost 1000 Charger in parallel with a Powerboost 500 Basic, works perfectly. Have both hooked up to a switch to power on both at the same time.
