Is there anyway to purchase another Smart Controller charging block?  Mine is broken...  I contacted DJI customer service and that was pretty much a joke.

If you can't find the original, see if you can find a 3rd party model that matches the specs of the original.  Isn't there some warranty period for the SC and accessories?  Maybe you can force a return?

Any 12v / 2a Smart charge will work I'm using a RavPower unit I got from Amazon, works great.

For example:

Hello and good day kcole0929. Thank you for reaching out. When purchasing a charging block for your DJI Smart Controller please consider this specification for it to work properly on your DJI Smart Controller The DJI Smart Controller supports USB power adapters rated 12 V/2 A. Thank you.

Hello.
I wanted to ask if the charger Mu One 45w can safely charge the smart controller?

The smart controller charging cube is  rated at 3amps.  Anything less will charge slower.  And I've found off brand 5V 3amp ones charge slower too.  The manual says to use the DJI cube.  An option to buy the real thing would be nice.

The original power supply supplies 12V 2A

DJI should sell the charging adapter separately.  Some folks do not like to use any 3rd party adapters for expensive equipment like the Smart Controller.

I use this one, and the SC indicates it is fast charging:

RAVPower 24 watt charger that can fast charge the SC

I found the parent of the DJI Smart Controller charging unit. Here it is: https://www.aliexpress.com/item/32968861006.html It works just like the factory one.

For example:

I can also confirm this charger works. 24w same as the DJI charger.

Would this portable charger charge the SC at high speed? Thanks!

Does the Controller even support High Speed Charging?  If a USB-C charger is greater than the 12W 3A rating the controller will only draw the power it is rated for.  It can not over draw power so too much power is not an issue.  But if the Controller supports High Speed charging,  you want to use it for other devices or to simultaneous charge multiple devices then get a high wattage charger.

ive just brought a smart controller charger off {Amazon  America} they are $19.00---- or £20 delivered to the uk then buy uk adapter to fit it into you socket

i don't know exactly what is meant by "genuine" but that charger on amazon is not a "genuine dji" charger but in fact, i just yet another run of the mill slow charger....it's not even a knock-off.  i wouldn't pay $20 for that.
