Can the Geekvape Aegis mod actually pass water/dust resistance and military standard shock testing? self.electronic_cigarette

Briefly, the tests were...
These were all the tests I had planned to do, and the Aegis survived, so I decided to see how far I could go. I started throwing it against a brick wall. It survived three throws but failed to function after the fourth. The battery was also severely dented and it vented (but did not go into thermal runaway and burst). The inside top of the battery compartment was covered in battery electrolyte/solvent.
I was stunned the Aegis survived even one throw!
Tearing down the Aegis I found out what caused the failure. An important component on the regulator circuit board, the inductor, had snapped off. It was epoxied on and soldered but these are relatively large, heavy components and are one of the biggest causes of failures due to vibration/shock in power electronics circuits.
The inductor did not snap off though until I subjected to Aegis to extraordinary levels of abuse/shock. I don’t think this would happen in any remotely reasonable abuse of the Aegis, even if you work on a construction site, are hiking, etc.
OK, let’s wrap this up with a few observations and comments:

Briefly, the tests were...
- Kicking the device down 200m of concrete sidewalk.
- Unscrewing and firmly screwing back on the battery cap 100 times and then dropping the device into 1m of water for 30 minutes to check for battery cap seal wear/damage.
- Uncovering/resealing the USB upgrade port and then dropping the device into 1m of water for 30 minutes to make sure the seal stayed intact after an upgrade.
- Freezing the device in a block of ice overnight...just because.
- Dropping the device from a 2m height, random orientation, onto a concrete sidewalk 20 times.
- Washing it in warm soapy water to test the seals with a lower surface tension liquid.
- The front plate and up/down buttons popped off. Once this happened it was hard to keep the plate and buttons from popping off again. I could not find the up/down button actuator after it popped off during the 2m drop tests.
- The screws holding on the decorative metal “bumpers” around the leather popped out during the 2m drop tests and were lost.

OK, let’s wrap this up with a few observations and comments:
- This mod is permanently sealed, no servicing is possible.
- This mod’s water resistance depends on the hand sealing of the front clear plastic underplate with an RTV-type substance. I’d like to see a gasket used instead as it allows for more consistent sealing and faster assembly. This isn’t an issue with good enough QC and post-assembly inspection/testing though.
- A possible issue could be the battery that is being used, inspect it after any hard drops. If the top or bottom are dented in then replace the battery.
- I’d like to see a more spring loaded top contact for the battery, perhaps with a rubber stopper to prevent overtravel in case of severe shock, that could help prevent indentation of the top and/or bottom of the battery.
- To increase this mod’s impact resistance even further the regulator circuit’s inductor would need to restrained further, perhaps by using additional epoxy or even a frame of some type.
- While a good portion of the mod is protected by the rubber shell the decorative metal frame pieces offer no shock protection. I’d love to see the rubber overmolding everywhere. This mod is astoundingly durable as is though.
- A different method to connect the decorative metal bumpers to the device might be needed as the screws holding them on could eventually weaken their grip over time, even with just an accumulation of the effect of numerous smaller impacts.
- The lightweight cast metal shell held up very well. It is a single piece except for the battery compartment threads which are in a small steel (I think) cylinder pinned into place at the bottom of the mod.
- I did not test the user interface for the software or the durability of the 510 connector. The user interface has been covered by several of our favorite YouTube reviewers and I didn’t have the spare atomizers needed for the 510 connector testing as they would certainly be ruined by the abuse I put this mod through.
