    Excellent recharge device

    Love this charger. It does everything I expected it too and more. Couple it with a 3A power block and it will fast charge for you as well. Highly recommended

    The charger arrived in a timely manner. The ums4 charges 18650 batteries very fast using the q3 adapter that you need to buy separately. The batteries were charged in about 1 hour. It didn't matter if you had 1 or 4 regular or imr batteries in the slot using auto charge mode.

    This is a great little tool so far. I have charged 18650, AAA and AA batteries so far and I got great results. The charging parameters can be easily customized and you can put it on steroids with a little quick charge adapter with a matching power output . The automatic detection and setup of the charging parameters is perfect for most of the cases. The internal resistance reading is not very accurate, the same battery in different slots or the same one will show different values for the internal resistance for different charging sessions, and if it happens that the value shows over 250mohms, the battery may appear in a "POOR" state but don;t just go and throw the battery. In my case the batteries that occasionally showed POOR work perfectly. The charger displays the charged capacity since the charging session started, it would be nice to show though the total capacity, but that is not a big issue. It appears to be a reliable charger and very well constructed and, so far I've had no heat issues with the charger or the batteries I have used.
