New (to me) Summit Kamado E6 not fuel efficient on first overnight cook

I recently purchased a used Summit Kamado E6. I'm coming from a Smokey Mountain 18. I've read about how efficient these cookers are and how very little charcoal they use, so I was really looking forward to seeing how much less charcoal it would use compared to my WSM. Last night I attempted my first overnight cook using some Jealous Devil Max XL Charcoal Briquets. According to the Kamado E6 user guide, you should be able to get 8-10 hours of cook time using only 35-45 briquettes. I filled up my Weber chimney to the top with the Jealous Devil briquettes, which should have been the equivalent of about 100 briquettes, and dumped them in. After getting the WSK up to temp at around 11:00 pm, I adjusted the bottom vent to the smoke setting and closed the vent to about 1/3 open. After it settled in around 235, I went to bed.

I woke up and checked on the grill temp, and it was reading 238. Impressive I thought. But after about another 30 minutes, temps started going down and continued to do so . I went outside and lifted up the deflector plate, and pretty much all of the charcoal was gone. I'm really confused at this point, because I'm not understanding how this is possible considering the amount of charcoal I put in (especially compared to the instructions), and how efficient the WSK is supposed to be. On my Smokey Mountain, I would still have a considerable amount of charcoal left in the morning after overnight smokes.

Any ideas as to why it used so much charcoal? I've never used the Jealous Devil briquettes before; do they burn quickly? I've used their lump in my WSM for a number of smokes, and even that lasted longer.

Thanks.
 
I don’t think a Weber chimney held anywhere near 100 briquettes of JD max, but I could be wrong.

I’ll defer to other users but on my one low and slow I just dumped the bag to fill up the whole lower section. Put in the heat diffuser and it had tons of charcoal left after 10 hours.

Good luck, we have a few really experienced users who I’m sure will chime in once the coffee hits.
 
JD briquettes don’t last as long as Kingsford in my experience. I prefer lump, but I feel like that burns slightly faster than Kingsford too.

Just curious if there is plenty of creosote buildup, which will help it seal over time.

Also, is the silver fan port plug tightly inserted (bottom right side of the bowl)?

Same. I fill the bottom, light a small area and it will go a long time leaving much not started.
 
A full chimney of hot and ashed over coals might be the isssue. It will burn out quicker than adding ten hot coals to an unlit bed of charcoal. Minion method is more effective for long cooks.
 
Sorry, no pics. There was definitely not 100 briquettes, because Jealous Devil Max briquettes are larger than normal briquettes. But since the chimney is supposed to hold approximately 100 normal-sized briquettes, and I filled it up, it should have been the equivalent of 100. All of the charcoal went into the WSK unlit. I then lit some leftover Jealous Devil lump (1/6th of a chimney's worth), and spread that over the charcoal. This is what I normally do with my WSM as well.

Unfortunately, I don't have a way to monitor the pit temps after the fact. I use a Thermoworks Smoke X2, and it doesn't have historical information (and I wasn't awake).

The fan port is tight, although I do see smoke leak in the back (which seems to be a common issue) as well as where my probe wires run under the lid.

Thanks.
