Review :
Produk yg bisa dipakai untuk mengetahui brp besar voltase & ampere dari charger, usb port & kabel usb, dengan toleransi kesalahan deteksi yang masih cukup kecil. Kita bisa tahu mana yang memang sudah rusak/perlu diganti, khususnya charger/usb port.
Sangat berguna untuk mengecek third party power bank dan charger yang dijual di pasaran. Ternyata banyak charger dan powerbank yang voltasenya melebihi batas wajar (>5.20 volt) dan membuat IC regulator & batere handphone cepat panas dan akhirnya rusak.
