Quick question to SF KR1 owners

The CN200 (for the B65), CN400 (for the B90) and the C900* (for the B20) all require input of DC12V 1.2A
(* Note: No "N" in C900.)
SureFire have started using a 'digital' AC power supply like those found with laptops that can accept 110-230V AC. This uses an IEC-320 type C7 moulded "figure of 8" power lead that can be terminated with whichever AC plug your country requires.

Does this help?

SureFire offers kits for a number of different AC types and plugs:

1 (or no suffix) is for the USA.
2 is for the UK
3 is for the EU (and Korea?)
4 is for Australia

So the KR1 kit is for the USA. The KR13 kit is for the EU.
Remember to select -BK (Black), -OD (Olive Drab) or -YL (Yellow) depending on which colour Nitrolon G2 you have.
(Example: KR13-BK)

For the charging cradles:
CNxyy (Cxyy for 10X)
Where x = 2 (for B65), 4 (for B90) or 9 (for B20)
Where yy = 00 (for charger only), 11 (for US AC & 12V DC), 21 (for UK AC & 12V DC), 31 (for EU AC & 12V DC) or 41 (for Australia AC & 12V DC)
So you get CN421 or C941

For whole flashlights (L7/8AX/8NX/9AN/10X) a three-figure suffix is used:
"000" for flashlight only including one battery (8AX000) (Not available for L7)
"xyz" where x = 4 (for CN400) or 9 (for C900)
where y = 1 (for US AC & 12V DC), 2 (for UK AC & 12V DC), 3 (for EU AC & 12V DC) or 4 (for Australia AC & 12V DC)
where z = 1 (for 1 battery: 10X only) or 5 (for 2 batteries: B90 models only)
So you end up with 9AN415 or 10X931 or L7-445 for example.

Note that I'm very pedantic when it comes to SureFire product codes. If I put a dash "-" in then it's meant to be there.
