    I have two of these for use with a small solar panel when hiking. It takes a little finesse sometimes to get the magnet on the positive terminal but the size and weight are excellent for keeping AAA and AA rechargeables charged. Great for emergency use as well, it takes no space in a pack or luggage.

    Pros
    - Compact
    - Charges quickly
    - USB Powered
    - Indicator LED
    - Magnetic

    Cons
    - Poor fit on positive battery terminal RCR123A & 18650


    I really like this charger, it charges reasonably fast and has a status LED that is red when charging and green when the battery is fully charged. However there is one thing I do not care for. When you go to charge a battery and place the terminals on the negative side the fit is fine, however the Positive side will not fit around the battery terminal on RCR123A and 18650 batteries. This causes the charger to sit at an angle on the top of the battery terminal, making for an easily broken connection. Otherwise i think this charger is great.

    TL:DR
    I really like this charger but would like to see a slight change made to one or both of the contact points to better accommodate the positive terminals on 18650 and RCR123A batteries.
