## Customer Reviews

### ⭐⭐⭐⭐⭐ works for 4runner
*by T***G on March 27, 2021*

Was a good bump for output voltage on my 2005 4Runner. Downside was the fuze in a 3x3 baggie, one slip of paper for invoice, all in a 6x6x4 box without anything else in it. Certainly a waste of space...

### ⭐⭐⭐⭐⭐ With minor snipping, works great!
*by R***R on January 17, 2022*

Charges my AGM battery on my toyota vehicles as the alternator should.

### ⭐⭐⭐⭐⭐ did what it supposed to
*by E***. on March 23, 2022*

good and fast shipping
