### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Been working well for months
  

*by A***Y on Reviewed in the United States on June 11, 2020*

I use this almost every day and it's very light weight and easy to use. It does not have an amperage guage so if you're looking to switch between 0.5 and 1.0A then this isn't for you.This also does not have a digital screen to show how much your batteries have charged. It will show a light at the top that starts red with an uncharged battery and turns green when it's finished charging.Overall, if you want your batteries charged this will do the job.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Works.  Notice that it doesn’t come with a power supply
  

*by S***F on Reviewed in the United States on May 10, 2019*

I used this to charge a new pair of 3200mA-hr 18650 Lithium Ion batteries over night.  The initial voltage was 3.7V and the final voltage was 4.26V.  I used the power supply for a Raspberry Pi to provide the energy to recharge the batteries, since it didn’t come with a wall adapter.  It worked.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    As expected
  

*by W***M on Reviewed in the United States on May 28, 2019*
