I purchased this adapter charger for my home and kitchen vacuum cleaner and it has exceeded my expectations. Thanks to my knowledge gained in practice, I can confidently say that this charger charges the battery quickly and efficiently. I appreciate that it has a long cord, allowing me to plug it in anywhere in my home for convenient charging. The only minor con is that it's not the smallest charger, but that's not a big deal considering the excellent performance. Overall, I highly recommend this charger!
