Lumsing Grand A2 Fit: Simple is better

The saying “there isn’t enough time throughout the day” has become increasingly relevant to my life. I am a recent college graduate working my first full-time job at a biotech company. By the time I’m finished with work and the gym, it’s usually 8 p.m. when I get to my house. Factor in my necessary beauty sleep of at least 8 hours and that leaves me only three hours of free time during the weekdays.

The limited amount of free time has really pushed me to get rid of extraneous distractions in my life. RIP The Office reruns. I place a lot of value in simplicity when it comes to electronic accessories. I want to make my life easier so I can be more productive. It’s why I predominantly use the iPhone because I know what I’m going to get each time I upgrade. When I was younger, I loved getting to learn the ins and outs of new phones. I am slowly but surely morphing into a cynical 24-year-old grandpa.

Lumsing is a company that I can get behind because they emphasize a similar philosophy in their products. Lumsing is primarily an electronic accessories company who focuses on simplicity and function. Let me introduce you to one of their power banks that I have been using the past couple of weeks.

  • Brand: Lumsing
  • Model: Grand A2 Fit
  • Capacity: 10050 mAh
  • Input: Micro-USB DC 5V/2.5A; Type-C DC 5V/2.5A
  • Output: QC2.0/3.0 DC 5v-12V/3A; Type-C DC 5V/3.1A
  • Size: 3.8 in. x 2.5 in. x 0.8 in.
  • Weight: 7.33 oz.

The Grand A2 Fit comes with one regular USB charging port and a Type-C input/output. The great thing about USB Type-C is that it is reversible so you don’t need to worry about which way you insert the cable. The dual input/output functionality of USB Type-C allows it to charge and be charged by other devices. Quick Charge 2.0/3.0 technology is supported in the regular USB charging port.


Quick Charge 3.0 was developed by Qualcomm that allows your phone to be charged from 0% to 80% in 35 minutes. This new technology is only supported in a limited number of phones. The QC3.0 port will automatically detect if your phone is supported and if it isn’t it will change to the correct power output. QC3.0 is also backwards-compatible which means QC2.0 and QC1.0 supported phones will work as well.

The Lumsing power bank comes with built-in flashlights which can be turned on by long-pressing the side buttons. Each Lumsing device features four blue LED indicators that represent how much battery is left. Four blue lights indicate 100% battery, three blue lights indicate 75% battery and so on.

I find myself using power banks as my primary source of charging these days. Pacing around the lab and a relatively active lifestyle always keeps me on the go. I used this power bank simultaneously throughout the course of the past month. The Grand A2 Fit was primarily used to charge my iPhone 6S. I got around five to six full charges on my iPhone 6S. Android phones tend to have bigger batteries so you can estimate being able to charge your phone around three times. I was also able to use the power bank to charge my iPad from 20% to 100%.

I do not own a phone that supports QC3.o but I do have a friend who has an LG G5. I was extremely jealous of how fast it charged his phone. It charged his phone from 0 to 80% in 35-40 minutes which is around what Qualcomm claims. I charged the Grand A2 Fit right before I went to bed and it was fully charged when I woke up. The power bank does not support pass-through charging which means you cannot charge your phone and battery at the same time.

The Grand A2 Fit is a great portable battery to carry around in your pocket. It is about the size of an iPod classic so there should be no problem carrying that around in your pocket. Lumsing specializes in electronic accessories making simple yet functional products. It carries this theme into the Grand A2 Fit portable power bank. I can appreciate the simplicity of this charger, which is a relief in any busy person’s life. You can find the Grand A2 Fit on Amazon for $17.99.
