The interchangeable plug design is clever and the unit feels robust and well made, so switching entre UK and European sockets Has not presented a problem no doubt lugs and the locking mechanism will wear with normal use goal Eventually it shoulds last for ages. The four USB outlets are Labelled Universal, iPad, iPhone, iPad and the operating guide Suggests That Each harbor is Optimised accordingly but quite how I dont know. Everything I've plugged into it (smartphone, IP Camera, phone backup power pack and wireless speaker) behaved identically-have as far as I can tell, irrespective of the port used. My phone (with a 3000mAh battery) charged from 60% to full in more-or-less the same time as with the Supplied 800mA load on the qui area Seems to be OK but I dont know enough about Li-ion batteries to know if a high current load is better for battery life than a lower one. Thanks to batteryuniversity dot com info for the Following:
Increasing the load current Does not Hasten the full-load state by much. ALTHOUGH the battery voltage Reaches the peak Quicker with a fast load, the load saturation will take along accordingly. The amount of charge current Applied simply alters the time required For Each internship; Stage 1 will be shorting the purpose saturation Stage 2 will take longer. A high current load will, HOWEVER, Quickly fill the battery to about 70 percent.
This is an ideal multi-purpose USB charger Both at home and one for general use Those trips abroad. An excellent and Very useful bit of kit thanks to GlobalBuy for the opportunity to test the product in return for a free unit.
