Power banks that have built-in charging cables are great candidates for when you’re searching for a portable charger because there’s no need to carry around a charging cable, other than recharging the power bank.

Some power banks have two built-in charging cables and that’s useful to have when you have devices that use either of the charging cable, which once again absolves the need for carrying around a charging cable and more focus on just having the power bank on you.

What makes a power bank with a built-in charging cable very reliable is that it has a USB charging port that can be used by any charging cable.

However, even with all that said, about how built-in charging cables are a great implementation for power banks, there’s just one more step that can be taken.

This iWalk T08 8,000mAh power bank takes that step because it not only has 2 built-in charging cables, and a USB port, but it also has a USB port built into the power bank for recharging.

Power Capacity:

The starting power capacity of the iWalk T08 power bank is 8,000mAh and we don’t find that to be enough power to go with the changing capabilities that this power bank has.

This is because there are 3 methods of charging devices at the same time.

Also, the initial power capacity of 8,000mAh won’t be what you’re receiving because there’s a conversion of power during charging and that’s going to result in an average conversion of 70%; As a result, you’re most likely going to receive 5,600mAh of useable power.

Charging Smartphones with the iWalk T08

It’s with this power capacity that you should use this power bank for mostly charging smartphones because it’ll be able to charge most smartphones 2 times or more before the power bank needs a recharge.

Charging Tablets with the iWalk T08

If charging larger devices like tablets such as an iPad, it’s best to use Mini tablets with the charger because an iPad Mini 4 has a battery capacity of 5,124mAh and so it’ll be able to charge to its full power, but it’ll take the entire power capacity of the iWalk to get there.

Charging an iPad Mini 2 which has a power capacity of 6,470mAh is going to result in a nearly full charge.

It’s quite futile to charge a Full-Sized 12-inch iPad to its full power because it’s just going to be charged halfway.

Output Charging:

There are 3 ways to charge your device with the iWalk power bank and this is the strongest point of the charger.

There’s a built-in Lightning charging cable for Apple devices like an iPhone or iPad; then there’s a Micro-USB charging cable to charge Android devices.

Lastly, the power bank has a USB charging port that can be used by any charging cable.

Now, this all sounds great. If you have devices like smartphones that require either a Lightning or Micro-USB charging cable to charge, then you don’t even need to carry around a cable. There’s the USB port to charge a 3rd device as well.

However, the Max Output power of the power bank is the only 5V/2.4A, so if you are charging 3 devices at once, then that’s going to result in slow charging speeds for the devices that are charging.

So it’s best to charge 2 at the same time at most, and that way you won’t slow down charging too much.

Even though the Max Output charging speed of the power bank is slow, you can still potentially charge most smartphones at their max charging speeds and you can even charge an iPad at its max charging speed with the Built-In Lightning charging cable if you’re charging it alone.

Input Charging:

This is the real highlight of the power bank because there are 2 ways to recharge it.

There’s a built-in Input recharging cable and a Micro-USB Input. As a result, you don’t even have to carry around a Micro-USB cable to recharge the power bank because the power bank itself already has it! How cool is that?

The recharge rate of the power bank is 5V/2.0A and as long as you’re plugging the power bank into a 2 Amp wall charger to recharge, then that’s going to result in a recharge time of 5-6 hours.

Size and Weight:

It’s a very portable power bank that you can take with you nearly anywhere.

This is because it has a length of 5.6 inches, a width of 2.7 inches, and a thickness of 0.6 inches. The weight of the charger is 6.5 ounces.

It’s about the size of smartphones and is so thin that it can potentially fit into a back pocket. It’s also lightweight that makes it perfect to carry around if you want to.

Functional Components:

Even though there’s quite a lot going on with the power bank, it’s still easy to use.

The 2 built-in charging cables are to the side of the power bank and at the bottom of the charger is the USB charging cable.

On the short side of the power bank is where you’ll find the USB port, power button, and Micro-USB Cable. On top is where there are 4 White LED power capacity indicators.

Charging automatically starts when you use the charging cables or the USB port; so you’re mostly going to be pressing the power button to check the power capacity.

The built-in USB charging cable is capable of data transfers, but it’s only compatible with doing so when you’re using the Built-In Lightning charging cable or the USB Output port; the Micro-USB built-in input cable does not feature data transfers.

Just keep in mind that this may cause Pass-Through charging to take place and that can be harmful to your iWalk power bank.

The Matte finish that the iWalk T08 uses is very useful for holding the charger and it’s not slippery.

Structure and Material:

It’s made of plastic but it’s built very well which makes it usable for each day.


On the tech side, there’s not much that iWalk gives to on but even when you’re charging 3 devices at once, there aren’t any hangups with things like heating up and that’s a good sign that the power bank is good at managing heat.

Other than that, the iWalk portable charger just uses regular Lithium Polymer batteries that can go through 500 charging cycles.

We think that this iWalk T08 power bank is something that you should give a chance because it has 3 ways to charge from it at the same time, and the best part is that you don’t even need your charging cable to use the power bank.

You can just pick this power bank up from your desk and head out, and that can’t be said about too many portable chargers.

You don’t even need a Micro-USB cable to recharge the power bank because there’s already a cable that’s built into it.

The power capacity and charging speeds aren’t the best, though, and it’s mostly meant for smartphones because that way you’ll at least be able to use the power bank multiple times over. You can use the USB Output port with any charging cable that you have.

Not the highest power capacity to charge 3 devices at once and the charging speed isn’t that fast either.

For the most part, charging 2 devices at once is going to be the best option. Although we do find it awesome that you can charge 3 devices at once.

You don’t need a Micro-USB charging cable to recharge it and instead, you can just use the Built-In USB cable.


It’s not that large, actually thin, and lightweight; which makes it easy to take with you while you’re on-the-go.


Not the best build, but the iWalk power bank can withstand everyday use without being damaged.


A lot of power banks on the market are labeled “Universal Power Bank” for marketing purposes, but this iWalk power bank takes a different path. It basically can be universally used with any USB charging device at all times because it has the built-in charging cable to do so and even a USB Port to use your cable.

Couple that with the ability to recharge using the built-in USB charging cable and this may just be the most reliable power bank ever.

  • LED Power Indicators: 4 LED Dotted Power Capacity Indicators
  • Size: 5.6 x 2.7 x 0.5 inches

If the power capacity and charging speeds are improved on this power bank, it’s going to blow a lot of fish out of the water. We love that it has all the necessary charging cable to make carrying your charging cable irrelevant.
