New Trent PowerPak+ (NT135T) 13500 mAh Battery Pack Review

This is the first time I write a review about a battery pack. I honestly never paid attention to these little things, but now that I have used a couple, I think I can no longer travel without carrying one in my bag the whole time.

A little side story before I start reviewing the New Trent battery pack, I used to have the i.Sound 16,000 mAh battery pack. I liked the i.Sound, but it did come with few caveats that I did not like. For Example, the i.Sound needs its own separate wall charger, unlike the New Trent NT135T, can charge anywhere from a microUSB cable (included). Another thing with the i.Sound is that it is too heavy, specially for traveling! The i.Sound weigh about 1.4 pounds (635 grams) which is a bit on the heavy side. The New Trent PowerPak+ NT135T weigh only 10 ounces (283.5 grams) which compared to the i.Sound, is about almost 3 times lighter! I understand that the i.Sound is 16,000mAh vs. New Trent 13500mAh, there is not much of a sacrifice in power, but much to gain when it comes to weight and size. Also, the New Trent NT135T is about half the size of the i.Sound!

When I first received the New Trent NT135T and held the box, I was shocked at how light it is, I almost thought that the box was empty and I was scammed! When I opened the box and saw the New Trent is actually in there, it was really a happy surprise of how light it is.

In the box, they include a nice good quality microUSB cable for charging or for using with devices that use microUSB, also, they include a little nice pouch for carrying the New Trent NT135T around, which they do not mention on their site. The addition of the pouch was welcomed!

My first impressions when I held the actual battery pack, was that how well it is made, it is really of a good quality plastic material. The whole device is made of matte finish which is good because it will not show any scratches and is easy to hold. It is about as tall as the iPhone 5/5s and about as thick as two and a half iPhones stacked on top of each other.

The New Trent PowerPak+ NT135T has two USB ports, one is labeled for smartphones which has output power of 1.0A and the other USB port is labeled for Tablets with output power of 2.1A. Of course you can plug in your smartphone to any of the USB ports, but in order for most tablets to charge faster, you must use the 2.1A port.

I actually bought the New Trent NT135T because of my recent travel plans from Hawaii to Washington state. I am writing this review from Seattle and it is my last day here before I head back in couple of hours (5 days trip). I have fully charged my iPhone 5S with it about 8 times now already, the battery pack still powers on, but I think it is about to die soon, my iPhone 5S is fully re-charged and ready to take on the day. Needless to say, I am pretty happy with this little thing, it helped me keep my iPhone charged for the whole trip.

The only little thing that bothers me, and this is with all the battery chargers and not just New Trent NT135T, is that each USB port outputs different power for different devices. In the future, I wish they can just make both USB ports output 2.1A/2.4A for fast charging and not have to label each port for Smartphones or Tablets. Besides that, I am really happy with my new toy. I would totally recommend it to anyone who is in the market for one. The quality is great, lots of power, and it is really light and small to carry.

      Hi Mal,

      I honestly use this device almost on the daily basis ever since I first bought it. So far so good. I keep it in my messenger bag at all times and plug my iPhone to it when I am commuting to/from work. It still works and charges like brand new and works as expected. I totally still recommend it.

      Hope this helps.
