The USB wall charger comes with quite a few features and advantages to protect your device. These are listed under:
1) There is a heating protection function which prevents the AC wall adapter from acquiring too hot despite the fact that it is charging. I have heard that some other inexpensive USB wall chargers bought from Amazon can result in the adapter to overheat and catch on fire.
2) There is an overcharge function which will detect when your battery is totally charged so that it cuts out charging. I cannot say if other dual USB wall chargers sold on Amazon have the same safeguard function.
3) The structure is really good top quality. I have seen electronic devices sold on Amazon where you look at it and think "if this lasts a month, I will be shocked". That is not the case with this charger.
4) There is a dim blue light. This indicates your area will not look like it is lit-up like a Christmas tree. This can be handy if you charge at evening in your bedroom and the vibrant LED light on some chargers can maintain you awake. This charger has a dim blue light, which is also convenient when you are travelling and staying in a hotel. The dim blue light will hopefully remind you that the wall charger has not been packed in your bag so you never forget it just before you check out.
5) The two ports can be employed to charge different brands of wise phones, tablets, cameras, GPS etc. The charging device can be utilized to charge Apple products. It doesn't matter what other devices are plugged into either port.
6) BL Brand is a business you can trust and Amazon is a location where you can invest in safely and get free of charge shipping for purchases of $25 or more. Etekcity Brand make sure their consumers have obtained the product by following up with emails that also include handy ideas and FAQs on making use of the dual port wall charger.
If you would like to buy this product you can find a great combined USB charger at Amazon. If you want a dual USB charger I would advise this 100 %.
