I hope that I am not violating any group buy rules by asking this question here, and if so, please let me know.
After expressing interest in the group buy currently in the ‘looking for interest stage’ I went looking for more information on the HMD10 3 in 1 holster / charger / battery bank. I have found it for sale at two different prices on BangGood.
Expensive one is currently $29.39 and lists the weight as 235g (without battery).
Cheap one is currently $13.43 but lists the weight as only 98g (without battery).
Can anyone who is more experienced with specifications and reading these web sites explain what the difference is?
