Choosing a charger is a very important issue that should not be disregarded, especially if your charger has been lost or burned. Just go to a regular retail store and buy there exercises – boring and expensive. Good that we have such a marketplace like Aliexpress where the prices can make you happy.

Quality and delivery

Features: three USB ports output and the presence on the front panel led screen that shows current consumption and voltage drop, if such was noticed. On weekends indicators 3 ampere at 5 Volts.

To me the price is this «miracle» was released in 7.76$ considering the discount. Not so cheap, but if a charger with similar features to buy from us in retail, that it will cost you twice the price. Recall that for such broadcast saves is not worth it. For the chargers with a price below two dollars won’t even look!
