    Power bank 4000mAh
    Легкий. Весит 140 граммов (как мой смартфон).
    Большой плюс - это провод, который можно уложить в аккуратную ложбинку в аккумуляторе. И не нужно носить с собой отдельно аккумулятор и отдельно провод.
    Поверхность выолнена из немаркого пластика. Он не глянцевый, поэтому никаких переживаний по поводу оставленных следов от пальцев. Он не матовый. Какая-то особая поверхность, благодаря которой удобно держать (не скользит в руках) и не так сильно марается. Поэтому пусть белый цвет не отпугивает тех кто боится маркости.
    Нет кнопки вкл/выкл, такое ощущение, что аккумулятор всегда готов к работе. Если его не трогать, то он лежит себе тихонько и лежит. Стоит взять в руки и включится индикация от небольшого наклона и/или щелчка по корпусу. Даже при извлечении микроЮСБ штекера из корпуса индикация может включиться.
    В общем, для меня так и осталось загадкой по какому алгоритму индикация (показывающая уровень заряда) включается.

    Leve para todo o lado
    Bateria pequena leve e prática. cabo USB/micro USB torna-a numa bateria portátil ainda mais portatil pois tem tudo numa só peça e não há preocupação em procurar o cabo quando este está ali mesmo conectado a parte lateral da bateria.
    Dimensões muito agradáveis visto que se assemelha a um telemóvel de 5" com espessura reduzida.
    interface simples. Luzes led indicativas de capacidade atual da bateria.
    Não tive a oportunidade de experimentar mas agrada-me a bateria pela sua praticabilidade.
    Led indicativo com capacidade liga facilmente com pequeno toque.

    Great Battery for little price, super thin
    I took it just in casem to have a spare one but this battery it's just great! I love it! It's super thin, as my phone, and with the cable built in, u don't have to worry about anything_ just take it, and your are fine to recharge your phone on the go, at least one time! so it's ok as deal!
    The price now is less down about 3$ instead of when i bought it, for the same price, so not so happy about this....but is life, i guess!

    powerbank pagata 5 €
    è molto sottile, infatti non ingombra gli spazi. In molti pensavano fosse un altro cellulare ed è molto utile il cavo laterale.
    Un altro pro è il sensore che "battendo" la powerbank, ti dice quanto è carica. Ogni pallino corrisponde a 1000 mAh e infatti ce ne sono 4.
    inizialmente caricava abbastanza velocemente il cellulare. Ora invece devo tenerla costantemente attaccata per caricarlo spendendo il triplo del tempo. Salva comunque la mia giornata universitaria per quello che mi è costata.
