I have 2 USB phone chargers - the LG charger is rated 5.0V, 0.7A and the Samsung charger is rated 5.0V, 1.0A. And I have a portable powerbank which takes hours to charge using any of those chargers.
Is it safe for me to get one of these Y-cables so I can connect it to both USB chargers for a combined 1.7A so that I can charge the powerbank faster? http://www.amazon.com/Black-Female-Extra-Extension-Mobile/dp/B00L32D088/ref=pd_sim_147_4?ie=UTF8&refRID=05Z674PCDMHS
