Now that most power banks have 2 charging ports, the next step is for you, the customer, to know what those charging ports are capable of.

Just because a power bank can charge 2 devices at once does not mean that it’s a great power bank because those charging ports might have slow charging speeds or one port might have a fast charging speed and the other port has a slow charging speed.

That is mostly the case with a few power banks on the market which is why it’s important to know what portable chargers hold value when they have 2 charging ports.

This is the iDaye 14,000mAh power bank that has 2 charging ports and enough power capacity to last you quite a while. However, let’s take a deeper look to see how it fairs in the field.

Power Capacity:

The iDaye power bank starts with a power capacity of 14,000mAh and that’s going to change during charging. Just how much will it change? Quite a bit.

This is because the power bank uses just regular Regular Lithium Polymer batteries that convert energy just efficiently enough, and then there’s a transfer of power through the charging cable and to the device that you’re charging.

All of this is going to make the conversion of energy at a normal rate fo 70% and that’s going to result in an Output power capacity of 9,800mAh. This amount of power capacity, although quite a lot lower than the initial one, is still useful for charging 2 devices at once and charging smartphones a few times over.

Charging Smartphones with the iDaye Power Bank

For example, you’ll be able to charge an iPhone 6s about 5 times to its full power capacity or you can charge a Galaxy S7 to its full power 3 times over.

So for the most part, you’re going to want to charge smartphones with the iDaye Power bank, because despite it boasting a 14,000mAh, the Output power capacity that you’ll actually receive is lower than that.

Charging Mini Tablets with the iDaye Power Bank

If you do plan on charging tablets, then we recommend taking the Mini route and mostly charging Mini tablets because that way, you’ll be able to charge tablets like the iPad Mini 2 or iPad Mini 4 series once, and still have enough power capacity on the iDaye power bank to charge a smartphones to its full power.

Charging Full-Sized Tablets with the iDaye Power Bank

Charging a full-sized tablet like the iPad 12-Inch version will result in the portable being close to its full power, but it’s going to take the entire power capacity of the iDaye power bank.

Output Charging:

There are 2 charging ports on the iDaye power bank and thank goodness the charger doesn’t have set charging speeds on the charging ports.

Each of the 2 charging ports is capable of an output of 5V/2.1A and the max output of the charger is 3.5A.

So if you’re charging 2 devices at once and the power bank is being pushed to its charging limits, then each of the charging ports is going to be outputting 5V/1.75A. That’s not a bad charging speed for 2 devices charging at once, and it’s a really good charging speed for smartphones.

However, it’s important to know that this power bank does not feature Quick Charge and so it won’t be able to charge Quick Charge compatible smartphones at their max charging speeds.

Also, if you want to charge a tablet as fast as possible, then it’s best to charge it alone because when you add another device while a tablet is charging, then it will most likely limit the charging speed of the tablet.

For the most part, the charging speeds and design are done very well, but if there’s just one flaw, it’s that having each port Output 5V/2.4A would have been better because that’s the max charging speeds for most tablets like iPads.

Input Charging:

The max recharge speed for the iDaye power bank is 5V/2.0A and as long as you’re using a 2 Amp wall charger, the power bank will be able to recharge within 7-8 hours. If you’re using a 1 Amp USB wall charger, then it can very well take about 16 hours for a full recharge.

Size and Weight:


It’s quite a large power bank but not too large that you can’t hold it in a single hand, we just think that it should be smaller and easier to hold because it is bulky.

It has a length of 5.7 inches, a width of 2.8 inches, and a thickness of 0.7 inches. The weight of the power bank is 9.6 ounces. Not the lightest or smallest power bank, but it does well enough, provided that you’re willing to carry around the half a pound weight that it has.

Functional Components:

On the short side of the power bank, is where you’ll find 2 USB charging ports and a single Micro-USB Input port. On the long side of the charger is where there’s a power button and on top of the power bank is where there’s 4 Blue LED power capacity indicators.

If there’s just a single important thing to know about the iDaye power bank, it’s that charging DOES NOT automatically start. Once you connect a device to the power bank, then you must press the power button to begin charging.

This kind of design is actually old and most power banks are supposed to automatically start charging, without that, there’s a possibility that you may connect your device and forget to even press the power button to begin charging.

Structure and Material:

It’s made of plastic and it’s very sturdy so it can be used every day. There are just 2 pieces that make the charger whole with just the top and bottom piece.


iDaye doesn’t specify what safety protections they use with this portable charger, however, they do have the certifications like FCC, CE and RoHS to set the basis for safety for you and your devices at least.


The iDaye power bank is meeting just at the line with it being a good power bank. There’s nothing too special about the power capacity, or size of the portable charger. However, what makes it very reliable is that it has just enough power capacity, and the charging design is great for charging 2 devices at once because charging speeds are not limited to just a port.

We think that if you need a 2 port power bank that’s going to provide enough longevity and charging power, then this iDaye power bank is the one for you.

The power capacity that you can actually use is quite a lot lower than the initial one because of the conversion of energy. Charging is good with the charger because it has a max Output of 3.5A and each of the charging ports has a charging speed of 5V/2.1A.


Not small or even lightweight. However, you can still manage to hold the charger if you wanted to, or place it into a bag to make portability more bearable.


Not the strongest build but it’s built well enough that it can be used every day.


The iDaye power bank meets just at the line of what we consider a great power bank because it has a power capacity to charge smartphones multiple times, and it can even charge some tablets to their full power.
