    For now it works well

    I bought this Erayak from to replace a third-party product which unfortunately had failed. Compared to the previous one, it has longer cables, while it remains at rest when it is in maintenance function.
    The charger seems to work well: when I take the car for a few kilometers and then I reattach it to the charger, it charges for a few seconds (orange light and fan on) and then goes into maintenance; it means that the charger notices even minimal drops in charge and restores them in a few seconds.
    I hope the weather is more magnanimous with this charger than with the previous one, but the cooling fan leaves me hopeful.
    As a reference I can tell you that it charges a 55/60 Ah (12v) battery in about 12-15 hours.

    ERAYAK charger: great buy!

    Arrived on a Sunday, several days early. I tested it immediately because due to Covid, the batteries of my family's cars (which had been forgotten in the garage) had run out. Attached to the first, it shut down after just 6 hours as the battery was fully charged. The second, probably more discharged, took 14 hours, but the battery is very efficient. What can I say except that in my opinion the product is fine and that its price is low for the quality and the work it does. I forgot that it is also great for maintaining a charge: just plug it in and it turns on and off depending on whether the voltage drops over time.


    Ideal for those who have to leave the car unused for months; the battery is not damaged and the car restarts easily.
    Despite the unclear instructions in my opinion, it is practical and easy to connect in a minute and allows you to avoid disassembling anything. It is activated as soon as the battery charge drops even slightly and stops by itself when it is charged.
    It therefore keeps the battery always charged without wasting current or overheating.
    Top product also for the price.
