Для экстренной подзарядки раньше использовал переносную батарею на 12000mah, но та была чересчур громоздка и тяжела для ежедневного ношения.
С этим Wievsonic все стало гораздо проще и он легко помещается в маленькую сумку, карман, куда душе угодно.
Батарея хорошо держит заряд, хватает для двух полных подзарядок смартфона. Удобная индикация и кнопка включения, спрятанная на торце корпуса.
Единственный минус то, что маловато разъемов в комплекте, но это легко решаемо, так как от прежних девайсов их накопилось на все случаи жизни. Короче, берите - не пожалеете.

Весьма полезная и иногда просто незаменимая вещь! Особенно в дороге (в поезде, например), на даче. А еще полезная - если у каждого члена семьи - своя модель мобильного. Из вложенных разъемов используем уже три %)))

Наконец-то дождался этого маленького пакетика с долгожданным аккумулятором. Признаков жизни он никаких не подавал и я просто думал, что он в дороге разрядился и его необходимо зарядить. При подключении к USB загораются два первых светодиодика и на этом всё заканчивается. После двух суток зарядки эти же два огонька продолжали гореть, но все попытки определить уровень заряда батареи согласно их инструкции терьпели фиаско. Естественно, ни о каком заряде других устройств от этой батарейки и речи быть не может.
Создаётся впечатление, что китайцы шлют нам всякое барахло в надежде на то, что цена возврата его им назад будет сопоставима с ценой самого товара и не каждый на это пойдёт.
