I think that it is like a motel . In a motel what is expected to be carried by the customer . phones and a pad is about it. Now ask the same question for a diving boat's the variety of items and types increase exponentially. If all the stuff taken on a dive boat was taken on a plane or to a motel in the varieties and quantities in % of passengers,,, the motels etc would have more restrictions also. Airlines already deal with most of the main dangers they are aware of. Try taking a hot plate to a motel room.
I was specifically asking about charging batteries.

And many (most, all?) Caribbean LOB divers get there via plane and spend a night before / after in a hotel.

Is anyone aware of any type of battery charging restrictions anywhere else?
 
try to bring a DPV, Canister light and a couple video lights next trip and charge them on the plane.
The airplane I recently flew on had approx 450 passengers. I would be very interested to know the current draw from all of the plugged in devices. There were NO charging restrictions in place.

Scuba is not that special.
 
Boats will have to learn to deal with people wanting to charge

People are going to have to adapt to some sensible restrictions

I think. 8pm cessation is too early. 11pm would be better maybe

The only people that really need overnight charging are those with DPV’s and I’m sure they can be accommodated with some sensible planning

The question is are the operators and customers willing to withstand the higher costs that any revised legislation is likely to bring
If you actually have a watchman it doesn't matter what time things are charging.
 
And since the cause of the Conception fire hasn't been determined it may not matter at all. Battery charging may not have played a role. We have to wait and see.
 
Charge the batteries on a Zodiac and pull it 25 feet behind the boat with a rope/power cord umbilical. Crash axe in the stern right where the umbilical attaches.
Like I said already in the other thread, the charging station is where the smoking area is, 30’ off the back of the stern! Lol :)

USB 3.1 is now up to 1.5 amps at 5 volts. Most USB chargers are much lower and most are not pulling maximum. 1.5 amps at 5 volts is 7.5 watts. There is some heat loss in the charger so lets say 10 watts. (Even though it's not that much) A 20 amp circuit at 120 volts can supply 2400 watts, but by NEC code only 1920 watts continuous. So a single 20 amp circuit could supply 192 latest model USB chargers drawing the maximum. Reality is that one circuit could supply all 450 passengers and 2 circuits would do it easily.

it isn't just the current draw and wiring..

You are confusing charging phones, tablets and laptops with stuff like Video Lights, Canister lights, DPV's that are much higher capacity (energy) packs, produced in lower qty and quite frankly not always made well.

I have never seen a usb powered DPV, canister light charger. Nor video light for that matter. I have seen usb 18650 chargers however.
 
We don't pay others to be in them! Charter vessels are offering a service which you pay for, but not with your life!
Do you think hotels and store buildings and buses are not "grandfathered"?
