EasyAcc is one of the best known brands among manufacturers of portable batteries and those who have tried this type of product on Amazon it will be stumbled at least once in its batteries. The company has proposed the Metal 3000mAh battery, very small and portable and can also recharge the top of the range today.
The size of EasyAcc Metal 3000mAh are very similar to those of Vinsic Tulip reviewed in the past few days: we have a box with rounded edges of approximately 8.5 x 2 x 2 cm and weight of 78 grams, making it extremely portable.
The chassis is made of aluminum painted black, while the top is made of plastic with chrome effect and also houses the power button on and off. On the top side are located the four white LEDs indicating the charge, the USB port to connect the devices to recharge and the micro-USB port to charge the battery.
Charging EasyAcc Metal 3000mAh requires little more than three hours, because of the input current limited to 1A. With an input current of 1.5A, by comparison, would be needed about two hours.
The thing that amazed me most of this small battery is its ability to also recharge the Ecoo E04 Aurora Plus, a smartphone with battery 3000mAh: despite the loss of efficiency due to the output voltage greater than that of the internal battery, in fact, The battery is able to charge your smartphone up to 90% – an outstanding achievement that places itself above the direct competition. The efficiency of the battery, in fact, appears to be in the neighborhood of 90%, and this is an excellent result.
The charging speed is not very high, because the battery has an output of only 1A that, in fact, makes the charging of devices such as the latest top of the range or phablet with larger battery employ much longer to charge it. Unlike other similar products, the charge device only starts when you press the power button and not by simply inserting the cable into the USB port.
The only flaw is the use of plastic, in particular as regards the power key on / off a bit ‘dancer, gives the impression of a cheap product.
Low price, good quality materials (except plastics) and extremely high efficiency put this battery in their class, while the super-portability makes it possible to always have a way to charge your phone.
