These are excellent and very highly recommended. Leave your 18650 batteries (not supplied with item) in it and recharge using a standard 5v 2amp phone charger, single light is red when charging then turns blue when charged. Also has a button that you press for charge level as you can see in the pictures I was charging (red). Then pressed the button and its showing fully charged. Both button top and flat top 18650 batteries do fit, button top are a tight fit. Use decent quality batteries and you'll get great goggle time from this, great value and much better than a lipo as lithium iron batteries are not so sensitive to being discharged. Very pleased with this purchase. UK delivery took from Order 19 July 21 to Delivered 27 July 21, all good!

Отличный кейс для 2х18650 литий-ионной батареи с USB зарядкой. Подходит для моих очков Skyzone. Балансировочный кабель мне не нужен, мне не надо, чтобы болтались лишние провода с разъёмом. Провод немножко длинный, разберу при случае и укорочу. Зато можно надолго забыть о зарядке, установлю самые ёмкие 18650, прослужат долго.
