if you need to use 20 watts for your charging which this amp cannot supply, buy a larger psu. i have this charger and power supply. i would use power supplies that exceed what the x120 requires. i wouldn't use this psu for the x120 unless you charging batteries within the power supply's power rating. it should work with 2s, 3s, 4s batteries depending the size of the batteries.
This power supply is a good starter kit for those who are new into this hobby and looking for best value charger. A constant 15V DC output is nice for most entry level charger even in Hobbyking. Please do purchase this and you will not regret at all. All you need is a 3 prong Ac power cord and you are good to go! Not that noisy and is very cool when I use this to parallel-charge 6 3s 2200mAh lipo batteries!
