    Powr Bank / ładowarka
    Color:Black
    Moim zdaniem dobry wybór, jeśli posiada się już trochę akusów 18650 w szufladzie, np. jako typowe zasilanie latarki, a nie ma się zacięcia do montowania czegoś samodzielnie. Działa poprawnie zarówno w trybie power banku jak i w trybie ładowarki. Ładowanie jest dosyć powolne, na pewno nie jest to "szybka" ładowarka. Wskaźnik naładowania pokazuje stan każdego z akumulatorów z osobna. Obudowa wygląda na względnie solidną, raczej ni ma szans, żeby akumulatory wypadły przy byle wstrząsie - pokrywa odblokowuje się z wyraźnym oporem. Jedyne, do czego można się przyczepić, to trochę luźne gniazdo microUSB - trzeba uważać, żeby w trybie ładowarki przypadkowo nie rozłączyć zasilania.
    Suggestion
    Nic, co mógłbym wychwycić na początku użytkowania.

    Second life for Li-ion 18650 batteries
    Color:White
    If you have some unusable batteries (from notebook or something else), this is the best way how to give a second life for your Li-ion 18650 batteries.
    -good relation between price and quality.
    -informative display with back light (you can switch on/off), shows actual current and voltage.
    -good assembly of the device
    -device charges batteries separately
    -looks good
    I will recommend it to my friends.
    Suggestion
    no

    Зарядка
    Color:Black
    Отличное устройство два в одном - зарядка и повербанк. Можно заряжать 3 батареи 18650, причем они могут быть разной емкости и заряжаются параллельно. А вот для использования как повербанк нужны батареи одной емкости и отдают заряд они по очереди.
    Suggestion
    Нет.

    Tomo power bank
    Color:White
    Using for last 3 months. Works well. You can choose your own battery brand and use with this power bank. Uses 3 18650 batteries. Display quality is nice and bright. Gives information of charge and discharge status.
    Suggestion
    If charging current could have been displayed while charging the power bank.
