## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great Charger for 2-cell Lithium-ion Systems
  

*by D***D on Reviewed in the United States on January 16, 2020*

I purchased several of these as a low-cost alternative to the factory-supplied charger provided with an Ultrasabers lightsaber.  Provides the same dual-color status LED & switch-over to maintenance charge as the factory unit.  A perfect replacement at 1/4 the price!* Note:. This charger has a 2.1 mm tip.  It works with both older sabers with a 2.1 mm tip & also newer sabers with a 2.4 mm tip?

    Worked for exactly what we bought it for!
  

*by C***H on Reviewed in the United States on June 18, 2020*

My 15-year old son did the research & found that this was the plug he needed to recharge the light saber he got for Christmas. It worked perfectly & charged it in just minutes.

### ⭐⭐⭐⭐⭐ 







  
  
    Works well
  

*by K***L on Reviewed in the United States on April 10, 2021*

Works as it should. I am using it as a charger for a DIY device that uses a battery management module to charge 2 18650 batteries.
