Cons

  • Not too strong of a build
  • Charging design can be bad if you're charging 2 devices at once
(Last Updated On: May 7, 2019)

For the most part, power banks with 2 charging ports are a preferable option when it comes to choosing between a single and 2-port power banks.

Just think about it. Would you rather have 1 or 2 devices charging at one time while they’re both close by and you can comfortably use them?

With that said, though, it’s not necessarily about the amount of charging ports that a power bank offers.

This is because a portable charger can have 6 charging ports and those charging ports won’t mean anything if all of them offer just 5V/1.0A charging. Which is basically a slow charging speed for most modern devices.

This is the TeckNet power bank. A portable charger that is quite famous and well known in the UK, let’s see why.

Power Capacity:

This TeckNet power bank starts off with a power capacity of 10,000mAh and the Output power capacity that you actually receive can change depending on the way you use it.

This is because the power bank has 2 charging ports and uses Lithium Polymer batteries.

First of all, Lithium Polymer batteries aren’t able to give a better conversion rate than Lithium Ion ones.

Also, if you’re using 2 charging ports, then more power capacity will be lost during charging.

With that said, even if you’re charging 2 devices at the same time, it’s not going to deplete the Output power capacity too much, and most of the time you’re going to be receiving 7,500mAh of Output power capacity that you’ll actually be able to use.

It’s with a 7,500mAh that is best used for smartphones because that way you’ll be able to use the power bank multiple times before it needs to be recharged.

Charging tablets, on the other hand, would just result in the entire power capacity being used up, and no multiple uses.

Output Charging:

Many power banks are designed the way the TeckNet power bank is because it uses 2 charging ports that have their fixed charging power.

We don’t very much like this, but it is what it is and for the most part, we think that it’s just an easy way out rather than creating a connected charging circuit so each port can share charging.

However, let’s see what each of the 2 charging ports has to offer.

USB 1:

The first charging port is labeled “Output 1” and this is the charging port that you’re going to want to use at all time.

That’s because the charging speed of this port is 5V/2.4A. A Max standard charging speed that’s able to charge any device that is NOT compatible with USB-C or Quick Charge at its max charging speed.

This fast charging is very helpful if you’re charging a tablet like an iPad because they can be charged at their max charging speeds with this port.

Also, you should use your smartphone to charge with this port because it’ll charge it at its max charging speed.

Don’t worry about your smartphone getting damaged, because it won’t, since each smartphone and basically, any quality device is given a built-in protocol telling it just how much power it should need to charge.

So Output 1 is the port that you should use with the device that you want to charge the fastest for those times that you want to charge 2 devices at once, and also if you’re just charging a single device.

USB 2:

Output 2 is the charging port that you’re going to want to avoid. Mainly because it only has a charging speed of 5V/1.0A.

For the most part, a charging speed of 1 Amp is going to be able to charge very few devices at their max charging speeds. So when you’re charging 2 devices, this port should be used with the device that you want to charge at a slow rate.

Input Charging:

It has a standard recharge rate at 5V/2.0A and if you’re using a 2 Amp wall charger then you’re going to be able to get a full charge within 8-9 hours.

Design

Size and Weight:

Not too large of a power bank and we think it has a perfect size that can practically be taken anywhere because of its short length and thickness.

It has a length of 5.8 inches, a width of 2.9 inches and a thickness of 0.5 inches. So it’s a power bank that can fit into a pocket, not only is it quite thin but also because it only weighs 8.6 ounces.

For the most part, you can just walk around with this 10,000mAh power bank while you’re using a smartphone and the only time you’re going to want to set it down is when you’re charging 2 devices at once.

Functional Components:

It’s a very minimalistic power bank and that’s really how many portable chargers should be like. This is because all the charging parts: The Input, and the 2 USB Output ports are on the side of the charger. There are 4 LED power capacity indicators on top of the power banks. That’s it.

There’s no power button, and even though we find that unusual, we can understand why there isn’t a need for it.

Since charging automatically starts when a device is connected. However, it would be helpful to have a power button if you wanted to know the power capacity that’s left on the power bank, but now you’ll have to literally start using the power bank to know the power capacity.

Build

Structure and Material:

The TeckNet power bank has a rather mediocre, albeit, solid build. The centerpiece of the portable charger is made of Aluminum and the 2 side panels are made of plastic. So it won’t provide much protection against falls, so it’s best to be cautious about that.

Tech:

It makes use of a Safety Protection system that is able to keep you and your devices safe during charging. The use of Lithium Polymer batteries rather than Ion ones can’t be criticized simply because the Polymer batteries are what makes this power bank slim.

Reliability

For the most part, we found this power bank to reliable. It doesn’t have the best conversion rate to offer the best Output power capacity, neither does it have best the Output charging design; but it does well with what it’s got.

For what it does have, any USB charging devices will able to be charged at pretty fast speeds if you know what charging port to use and you’ll be able to go through many charging cycles if you’re using smaller power capacity devices.

Summary

Power:

Power capacity can do very well if you’re using smartphones, but if you’re using it primarily for tablets then you’re only going to be able to get a 1 full charge.

Overall, the charging speeds are good with the power banks having a Max Output of 3.4A.

However, the charging DESIGN is bad since only a single charging port is able to Output 5V/2.4A and the other one is very slow at 5V/1.0A charging speed.

Design:

A perfect portable design that makes it possible for this power bank to be taken nearly anywhere. It doesn’t have a power button and even though we understand why, checking the power capacity becomes just a little bit of a tedious task.

Build:

Not the strongest build quality for its physical features, so it’s best to stay wary.

Reliability:

The TeckNet power bank may not have the best of anything on the market going for it with this portable charger. It does, however, do a lot of things correctly enough to be helpful for most USB charging devices.

Conclusion

For the most part, this TeckNet power bank is just above Mediocre.

Mostly because it doesn’t offer anything special in the way of providing a great charging experience for every device that uses it.

We say this because most of the devices that you do use with this are going to be charged at a good enough rate with a good enough power capacity.

Sometimes good enough just isn’t enough.
