Scam product
What great product i bought depending on its reviews but it just last for 3 seconds and then it blow up … cheap quality

Burned up as soon as I plugged it in.
No indication on if this is 110v or 240v. I bought it, plugged it in and it burned up, smoke pouring out of it. This seller needs to be investigated for fraud. Omitting something is the same as a lie. Only one star because there was nothing lower to choose from.

Unsafe
As soon as I connected it to the battery it smoked and made a popping sound. It’s certainly not safe and only suitable for 120v

Perfect for my motorcycle, high quality tender
I have had this tender for over 2 years now and of course it works great. The brand is great, it keeps my motorcycle battery alive during the cold season. Easy to use and great value.
