RAVPower 10400mAh 3.5A Portable Charger External Battery Pack Power Bank with iSmart Technology (Wireless Phone Accessory)
I bought the black colored charger. My initial impression is that the
build is strong and solid metal with some smooth plastic finish. I feel
confident that it would last a long time. I like the fact that there are
2 ports to charge with. I also like that there is an indicator of the
remaining power level. When I charge it, I am able to tell when the
device is still charging and when the charging is over- which was
I have tried charging various devices ranging from my
Samsung Galaxy S4, my iPod Touch 4th gen, my family's iPhone, and in all
cases, it performed very well. It would almost charge 1% per minute.
am very please with the product. My only caveat, which is no big deal
is that the left port has a different amp power from the right side. I
emailed CS and although they answered me, the answer wasn't the easiest to
understand. Perhaps labeling the ports would solve the problem.
I highly recommend it.
In terms of Resiliency, this would not only help your cel phones to be charged but if you also have LED lights that are USB powered, such as the S2 or the S20, you will see the value of the product.
ps. this product was sold to me with a discount for an honest review.
