Compact loader (8.5 x 3 x 7 cm) - that fits in the palm of the hand - and whose weight is reasonable (130 g); four ports on the amperage of 1 to 2.4 or 6.8 A in total, are obviously the major asset of this device that allows simultaneous charging of several mobile phones, tablets, GoPro cameras, external batteries, etc. The two slots to 2.4 A are also able to adapt to devices connected to increase the loading speed. The test was conclusive: faster recharge, without overheating, with a significant space saving. A tiny blue LED indicates that the adapter is plugged in, but does not inquire about the end of the load, which would be my only complaint. The classy and nice design touch, thanks to a kind of rubber anti-scratch and shock rubber, does not spoil anything. Just as CE standards and lifetime warranty!
