Nearly every charging electronic requires a charging cable, or rather, EVERY charging electronic needs a charging cable. Whether it’s a USB wall charger, car charger or even a wireless charger, they all need charging cables to actually be utilized. With that said, a power bank is one of the charging electronics that needs a charging cable while you’re on the go. Leaving your house with your power bank is great, but not so great when you forgot to unplug your charging cable from your USB wall charger that’s in your room. As a result, you’re stuck with a useless source of power.
This is why power banks with built-in charging cables exist because now you’ll always have a charging cable or two with your power bank. That is what this LAX 4,000mAh Power banks accomplishes.
For having a 2 built-in charging cable that gives the ability to charge two devices at once, this power bank has quite a low power capacity of 4,000mAh. However, the Max Output of 2.0 Amps evens it out because then you manage to lose less power capacity during charging. As a result, the conversion rate of the LAX power bank is about 75%, which is going to leave you with 3,000mAh of useable power.
Mostly Meant for Smartphones
It’s a small power capacity, and this is mainly because this is a Mini power bank. So you’re going to be able to get about 1 or 2 full charges for most smartphones. Another important thing to note is that even though there are two built-in charging cables, you should still charge devices 1 at a time so you make use of as much power capacity as possible for the device that you want to charge the most.
You can charge tablets with the power bank, but the power capacity isn’t enough to be worthwhile for tablets in the first place.
There are two convenient charging options available.
A Lightning cable on one side and a Micro-USB cable on the other side. The max Output power that is available is 5V/2.0A at once. This is disappointing at first, because if you’re charging two devices at once with this power bank, then each cable will have approximately 1 Amp of speed to use.
This is why even though it’s great to have two built-in cables, it’s best to charge a device at a single time for power capacity and charging speed benefits; as you’ll have 2 Amps of speed when you charge a device alone.
It’s already a mini power bank, and the fact that it has two cables is already impressive, it’s not surprising that it has power capabilities to match the Mini size.
Recharging is done through a Micro-USB Input and the max charging speed for recharging the power bank is 5V/1.0A. As long as you’re using 1 Amp wall charger or higher to recharge the power bank, then it’ll be able to recharge to full power within 2-3 hours.
Size and Weight:
It’s a very small and lightweight power bank that is going to be very portable.
It has a length of 4.6 inches, a width of 2.4 inches and a thickness of 0.4 inches. The weight of the power bank is 4 ounces.
So it’s basically the size of an iPhone 5, which means that you can easily carry this power bank in your hand while you charge your smartphone; or you can place it in your pocket.
The two Built-in charging cables are to the side of the power banks and each of them is 5 inches long. The Micro-USB Input port to recharge the power bank is on the short side. Lastly, on top of the power bank is where there are the power button and a LED power capacity indicator.
The power button isn’t really a button, more of a sensitive touch area that you have to press down on to begin charging. Also, there aren’t multiple LED lights to show the power capacity. Instead, there’s just one Blue LED light that blinks to show the amount of power capacity that’s left.
4 Blinks = 100%
3 Blinks = 75%
2 Blinks = 50%
1 Blinks = 25%
This kind of method to measure power capacity is highly unusual and rather difficult to check the power. It would be better to have multiple lights to check the power.
Structure and Material:
The entire power bank is made of plastic, and it has a very strong build.
On the tech side, the power bank has lots of safety tech features to make sure that charging is stable when you’re charging 1 or 2 devices at once.
The main reason that you’re getting this power bank is because you have both Micro-USB and Lightning chargeable devices. Once you get this power bank you’ll have a chance of charging those devices at all times with the power bank because the power bank has those cables built-in. So the reliability is really good because you’ll always have the necessary cables to actually use the power bank.
With that said, the power capacity is small and will only be able to charge most smartphones 1 or 2 times at most. It’s a Mini power bank that has 2 Built-in charging cables.
It only has 3,000mAh worth of usable power capacity. Also, the Max Output of power is 2 Amps at once. It might seem rather bad, but the powering capabilities of the power bank go right in line with what the power bank is. Which is a Mini power bank, that has two built-in charging cables.
It’s as small as an iPhone 5, and that means you can hold it in a single hand or place it into your pocket. Portability is not an issue. However, the way of telling the power capacity could be better.
The entirety of the power bank is made of plastic. Not a rugged power bank but it holds its own.
If you have both Micro-USB and Lightning devices, then this power bank is going to be useful as you’ll always have a way to recharge both of those kinds of devices.
