ASPERX Laptop Power Bank 27600mAh

This power bank has worked flawlessly on all of the mobile devices I've charged with it, including several Android phones and tablets. The digital display shows the current state of charge. I also love that it constantly displays the power being delivered to each device (in watts) while charging. This has allowed me to tell whether certain charging cables I have are high speed or older and slower.

The dimensions are compact yet it's noticeably heavier than comparably sized power banks. That's not necessarily a bad thing though. The build quality is outstanding - everything looks and feels well built, with good quality, sturdy materials. I'd highly recommend this for all your mobile charging needs. It's also great to have this around for power outages.

Amazing build quality and material choices. The rubber on the bottom and side are great for setting it down in 2 different orientations. Charges incredibly fast, it's neat watching it charge and the 2 decimal place percentage is nice. It truly does charge at 140W. Super Fast Charges my phone was well.

This AsperX laptop power bank is an impressive device to have when you're in need of an aftercharge for your laptop when you're on the go.

I let my computer drain all the way down to zero and then plugged this device in to see how much of a charge it would give me. My battery is 71 Wh capacity and the battery pack charged it up to 98% in about 2 hours. I thought this was quite impressive. I still had enough to do a full phone charge as well and a little bit extra.

I will say it is heavy because of the mass for the battery but it'll give you the amount of power that you need. It really was handy when we did a long car trip for our kids so everyone had their own port for their devices so they can charge them as we went.

When you do have to recharge the battery pack, I would plug it in overnight so it does have time to get all the way back up to 100%.

All in all, I think this is a solid device that will make sure that your laptop will be in workable form when you need that power. It is well built and the digital screen for information on the batteries remaining power is definitely appreciated.

My work often requires me to be away from a wall outlet for extended periods, and my laptop's internal battery is not always sufficient. I needed a power bank that could deliver legitimate high wattage charging to my MacBook Pro, not just trickle charge it.
This AsperX power bank is a very well made device. The aluminum unibody construction gives it a substantial, premium feel. Small details, like the diamond cut edge on the power button, are a nice touch. It is heavy, as expected for a high capacity battery, but that weight adds to the sense of durability. The small OLED display is functional, providing useful information like remaining capacity, output wattage for each port, and even the internal temperature of the unit.
The charging performance is the most important aspect, and it delivers on its claims. It successfully negotiates a full 140W power delivery profile with my laptop, providing the same charging speed as the original wall adapter. At the same time, I was able to charge my phone from the other port without a problem. It has enough capacity to fully recharge my laptop at least once, or to charge my phone many times over. The 99 watt hour rating also means it is compliant with airline carry on regulations.
This is not a small, pocketable power bank for topping up a phone. It is a high performance tool for users who need to power and recharge demanding devices like a modern laptop. For that specific need, this is a top tier product that works exactly as advertised.

This is an absolute unit of a power bank. While it's slightly larger than a typical convenient power bank you'd carry around, this is perfect for powering bigger equipment. For me, I need a power bank that can hold up to powering a laptop since I bring it everywhere. A typical power bank is okay for my phone or something, but they don't stand up for powering a full laptop. This power bank on the other hand is perfect for it.

I'm not in the know-how for testing power and whatnot, but I can say that it holds a lot of juice and charges my electronics quickly. The bank is also very sturdy and has a thick shell to protect it from drops. It's supposedly made from aluminum alloy rather than cheap plastic so it's a big plus. The bank also has a screen that displays important information so you're not left guessing the capacity left and if you need to recharge it. It also displays other neat information like the temperature, and output and input wattage, among others. The plentiful amount of added ports means you also get to charge multiple devices at once and use as you see fit.

Other things I have to mention are the device meets safety standards and has the necessary certifications so you're not worried about it blowing up in your bag. The other thing is that they also provide warranty and tech support so you know they stand behind their product.

Overall, this power bank is really well made and does a great job of charging my electronics. It holds lots of power, lasts long, charges fast, has a display screen, and lots of ports to use. It's exactly what I needed to be able to travel with my laptop and I'm probably getting some for friends/family too.
