SmallRig Dual 21700 Reviews
Not a very secure latch

I like the idea behind this 21700 battery power supply. It brings my dead phone to 50% in 30 min. I like the replaceable battery. I don't like that the battery compartment cover pops open when handled, in my pocket or clipped to a bag. It needs a locking lever to prevent it from opening.
yup!

this is great even if its not on sale. small and easy to carry, but useful as emergency fuel for your phone, wireless mic, small light or anything that can benefit from a bit of charge.
