One of the better chargers out there easy to use and great quality. Your delivery is quick. Amain is the best place to shop for RC.

I have only got to use this once since I've purchased it. I found it very easy to use and learn, it does everything I need it to do, for the type Batteries I use. Very satisfied

Nick HamiltonVerified owneron Spektrum RC S2100 G2 AC Smart Charger (6S/12A/100W x2)

Wouldn’t recommend. $200 charger and won’t let me put batteries in storage mode. Doesn’t always even let me charge a battery. Kind of a junk charger. Wouldn’t recommend as I can’t ever use it.

Thomas Kakaraon Spektrum RC S2100 G2 AC Smart Charger (6S/12A/100W x2)

Be aware there is no case for the workbench as stated in the video. Really it’s just an overpriced charger. I bought it thinking it would bring my Smart batteries back to life that decided to discharge themselves past the point of no return after only a few uses. I run Spektrum controllers and receivers in all my cars and planes. For the money I like my Passport Ultra P2 or my HiTec X2 better because of the Bluetooth capability and they’re both half the price. If you want to throw good money on top of bad you should definitely buy this charger. Two stars may actually be too many but who knows. I’ve reached out to see if Horizon Hobby will do anything about the $200 plus dollars worth of batteries that I can’t use but I still haven’t heard anything back.

Gabriel BeachVerified ownerMay 18, 2023on Spektrum RC S2100 G2 AC Smart Charger (6S/12A/100W x2)

Nice unit but for some reason one of the charging port keep saying “wrong battery type” while no issues with the same battery when plugged into the other port. What an inconvenience to get this rectified, I’m very much disappointed!

What reviewers say

Six reviews of the Spektrum RC S2100 G2 AC Smart Charger (6S/12A/100W x2) average about 3.5 out of 5. Reviewers who praise it describe it as easy to use and well built, with quick delivery. Critical reviewers report that one charging port intermittently showed a wrong battery type error while the other worked, that the charger would not enter storage mode or sometimes start a charge, and that a claimed workbench case was absent. One reviewer considered it overpriced compared with competing chargers. Opinions diverge sharply, and the reviews are few, so the overall picture is uncertain.

  • + Easy to use and learn
  • + Good build quality
  • + Quick delivery
  • − One port shows wrong battery type error
  • − Will not enter storage mode
  • − Sometimes fails to start a charge
  • − Priced high for some reviewers
