### ⭐⭐⭐⭐⭐ Paid for itself after one use.
*by J***. on May 12, 2024*

So a friend of mine recently purchased a rebuilt battery for his 2019 Crosstrek, and barely 6 weeks later was having trouble starting his car, and in fact needed jumped twice to get home from work. In the meantime, he started travelling with the borrowed jump pack, just in case. This weekend I tried out this Konwei battery tester and was very happy with the results. I hadn't used it yet, so was holding off in writing a review, but sure enough, it was able to detect that there is indeed a bad cell in the battery and that it's cranking performance was LOW. Additionally, it was able to verify the alternator was indeed operating properly, eliminating that as a potential cause. So, for $30 it saved a $99 trip to Subaru for "diagnostics". My buddy gave me $25 for my troubles and saving him the trip, so the tester is basically paid for after 1 use, and already saved my friend $75. One caveat I've noticed is that compared to (much) pricier testers, it is NOT possible to run the charging test yourself, as the tester leads are only a couple feet long. So, I manned the tester while my friend started the vehicle and ran it to 2,500rpm's during the testing. But again, it's $30, so....

### ⭐⭐⭐⭐⭐ Easy to use
*by L***L on April 7, 2025*

Now I can check battery status on all battery types and priced is cheaper then I thought but not the product
