Block Erupter 49 Port USB hub fuse spec?

[Tasweb]

Hiya!

I'm new here so this can become my mandatory Newbie section first post!

Can anyone with a Block Erupter 49 port hub tell me what spec fuse is in it?

Mine has arrived with no fuse and there are no markings on the chassis to indicate what I should use.

2.5W x 49 = 122.5W .... At 5V that's 24.5Amps!!!!

The holder looks like an automotive one but they are rated at 12V so I assume 122.5W is around 15A (actually a bit over 10A) in a car fuse but then what type of car fuse is it as they come in many different physical sizes?

Anyone able to help?

[EDIT] I just found a fuse in the bottom of the shipping bag. It is a 40Amp (!) ATO style automotive blade fuse.
