Habe mich aufgrund des günstigen Kaufpreises für den Artikel entschieden. Die Verarbeiten ist nicht perfekt, aber für den Preis angemessen. Bin mit dem Produkt insg. zufrieden, da es bisher mit keinen USB-Geräten Probleme gab. Wer jedoch USB-Geräte mit hohem Strombedarf (z.B. USB-Scanner) einsetzen möchte, die ihren Strom über USB beziehen.

Involvement: эксперт (понимает внутренние работы) Ownership: меньще 1 неделя

Pros: Показывает вольты, амперы и даже высчитывает отданный ампер-час.
Поможет протестировать USB компьютера и зарядного блока питания, покажет сколько ампер-часов всосала батарея телефона.
Говорят, что есть защита от высокого и низкого тока, я не проверял.

Cons: В данной версии нет пищалки.
Цена в TD относительно цены производителя сильно завышена, я считаю, что справедливая цена на данное устройство 100-150 руб.

Other: Весьма оригинальная игрушка, аналогов не встречал.

Bottomline: Штука интересная, мне она понравилась.
