  • High power capacity
  • Features Quick Charge and USB-C charging
  • You can use 2 Input ports at once for faster recharging of the power bank


  • Heavy
  • Mostly meant for those that can use the fast charging tech that it features

The most useful aspects that a power bank can have is to have the ability to charge multiple devices at the same time. With that said, when a power bank does have the ability to charge multiple devices at once, the next important thing to look out for is what those charging ports are capable of doing.

That should be the case with quality power banks and the ones that you plan on purchasing are that the charging ports should have fast charging speeds and the Max Output of the power bank should be high enough so that you can use the fast charging that each port has.

In this case, this Lumsing power bank has quite a few ways to charge and all of them are able to accommodate both standard charging devices, as well as fast charging compatible devices like Quick Charge and USB-C.

Power Capacity:

The power capacity of the power bank starts at 15,000mAh and you’re going to be receiving an average conversion rate of 70%.

There’s energy lost during charging because the energy from the batteries has to convert itself to go to the device that you’re charging and also you have to take into account that energy passes through a charging cable and power is lost there too.

As a result, you’re going to be receiving about 10,000mAh to 10,500mAh of power capacity to actually use.

How Does the Power Bank do when it comes to Smartphones?

A power capacity of 10,000mAh is able to charge to charge most smartphones up to 4-6 times. Charging high capacity smartphones like the Galaxy S7 is going to result in 3 full charges.

However, if you have smartphones with a lower capacity than that, then this Lumsing power bank is going to be able to charge it about 4-5 times. Either way, you can expect numerous charges for lots of smartphones.

How Does the Power Bank do when it comes to Tablets?

Moving into tablets, this power bank can also charge them quite well, or at least it can charge Mini tablets very well. This is because mini tablets like the iPad Mini 2, iPad Mini 4 and the Samsung Galaxy Tab have power capacities of around 4,000mah to 6,000mAh. So you can charge those tablets about once to their full power and still have power left to use.

Output Charging:

There are 3 options for charging when it comes to this power bank. The

  • Smart USB port
  • the Quick Charge USB port
  • USB-C charging port

Smart USB Port

This USB port is mainly meant for standard charging devices because it has a charging speed of 5V/2.4A and it can charge smartphones that are not compatible with Quick Charge at their max charging speeds.

The same goes for tablets in general because an iPad has a max charging speed of 5V/2.4A and as a result, this port can charge it at its max charging speeds.

Quick Charge Port

This port is mainly for Quick Charge compatible devices. With that said, you can still use Non-Compatible devices with this charging port, but for standard charging devices, this port will only output 5V/2.0A charging speed.

So if you’re charging non-compatible Quick Charge devices, always use Smart USB charging port.

For Quick Charge devices, though, this port will be able to charge those devices very quickly at charging speeds of 5V/3.1A | 9V/2.0A | 12V/1.5A.


Lastly, the USB-C port on this power bank can be used as an Input and Output port.

You’re going to need a USB-C to USB-C charging cable to use this port as an Output port to use with your USB-C compatible devices. It has a charging speed of 5V/3.0A and can charge your USB-C compatible smartphones at their max charging speeds.

Not only can it can it charge compatible smartphones, but this port can also charge newer MacBook that use USB-C to recharge as well. However, if you do choose to charge a MacBook, it will charge very slowly.

Input Charging:

There are two ports that can be used to recharge this Lumsing power bank. There’s the USB-C port that can be used as an Input port, and there’s the Micro-USB Input port as well. Both of the Input ports have a recharge speed of 5V/2.1A.

With that said, if you’re recharging the power bank only using a single charging port, then a full recharge will happen in about 9 hours.

However, there’s a much faster way to recharge the power bank and that’s by using both the USB-C and Micro-USB Input ports at the same time. This way the recharge speed will be 4A and the recharge time will be 5 hours.

It’s important to now that you must use a 2 Amp USB wall charger to recharge the power bank as fast as possible.

Size and Weight:

It’s not too large, and about the size of a smartphone.

This Lumsing power bank has a length of 6.2 inches, a width of 3.1 inches, and a thickness of 0.7 inches. The weight of it is 12.4 ounces. Not too large or too small, and neither is the power bank lightweight. For the most part, you can hold this power bank, but most likely not for long periods of time.

Of course, if you’re charging multiple devices at once, this thing is going to have to be set down.

Functional Components:

All of the charging ports are on a single side of the power bank, and this includes the 2 USB charging ports, USB-C port, and a Micro-USB Input ports. To the long side of the power bank is where you’ll find the power button, and on top of the charger is where there are 4 Blue LED power capacity indicators.

Charging automatically starts when plugging a device into one of the charging ports, so the power button is mainly meant for checking the power capacity that’s left.


Structure and Material:

It has a solid build, and even though the power bank is made of plastic, it can still be used every day without wearing down.


On the tech side, the Lumsing power bank uses Short-Circuit, Surge protection and other safety measures to make sure you and your devices are safe during charging.

This Lumsing power bank is very powerful with all of its charging options because each of them is able to provide powerful charging for each kind of device that they’re meant for.

A standard device will charge at its max speed with the Smart port, a Quick Charge compatible device will charge at its max charging speed with the Quick Charge port and you can charge USB-C compatible devices with the USB-C port as well.

Most power banks in the 15,000mAh power capacity take quite long to recharge, but that’s remedied because this power bank is able to recharge within just 5 hours because you can use 2 Input ports to recharge it faster.

With all that said, this power bank is going to be the most reliable for those that can use the special charging tech like Quick Charge and USB-C charging that this power bank features. If you want this power bank and you’re only using it to charge a standard device, then you’re going to be using only 1/3 of the power bank’s capabilities.

Even after its conversion, this power bank can still charge smartphones numerous times to their full power capacities.

It can even charge the tablet, however, it’s best to use it with Mini tablets because it can charge most of them once and still leave power left over. There are plenty of ways to recharge devices, and two of the three ways are mainly for fast charging technologies.

It can recharge 2x times faster than most traditional power banks because you can two of the Input ports at the same time.


It’s not too large but it can be difficult to carry for long periods of time. This is because it weighs quite a bit.


The Lumsing power bank has a tough build but it’s by no means a rugged power bank.


For the most part, this power bank is built on the assumption that you either have a Quick Charge or USB-C compatible device, since this power bank has both of those charging technologies. Using those charging technologies is what’s going to make charging more reliable and overall makes this power bank reliable.

It’s best to reconsider for another power bank if you just plan on charging your standard charging device with it.
