Undoubtedly one of the best power banks for those looking for something they can lose with their laptop, this Aisung model fits all of the criteria we’re looking for when searching for a power bank. It’ll work with any of the models in our list of the best laptops under £500.

Firstly, it has a UK plug socket for AC output., which can support 100 volts. This means that it’s good for using with your laptop, but it can also be used to power other things as well. Not all power banks have an AC port, so this is definitely a big plus for this device.

But, this isn’t the only port you can connect to with this bank. it also has a USB output port, as well as a USB-C port too. You can charge it with a standard micro USB port. There’s a handy flashlight you can use to give yourself some light if you’re using the power bank in a dark location (camping etc). At the top of the bank, there’s a percentage indicator to let you know how much charge you have left.

Probably the most important thing about this power bank is the amount of charge that it holds. With 31200mAh, you’re easily going to be able to treble the battery life of your laptop – you can’t ask for much more than this from a power bank. So overall, this is undoubtedly one of the better options you can choose.

Not everyone is going to want a power bank with the ability to connect to it via an AC plug socket. This can mean the bank needs to be quite large, and if you’re looking for something portable, then this isn’t the best fit. However, there are plenty of options for those to connect to a power bank is a different way, which means you can get a much thinner power bank.

In terms of ports, there are other ways that you can connect your laptop to this bank. it has 2 x USB ports on the side of the bank, which is probably how most people will want to connect to it. As well as this, it also has 2 x USB-C ports on the side of the power bank too. Having this two of each comes in handy if you want to charge your laptop and phone.

Another reason why I quite like this power bank specifically is because of it’s design. It’s made to be quite sturdy and long lasting, and the aluminium design means that you won’t need to worry too much about damaging it. Many cheaper power banks can be broken pretty easily, so this is an important feature to think about.

This power bank should be at least enough to give you another full battery life charge if you’re using a standard laptop, like a Macbook or a Dell XPS series. So for a combination of power and portability, this is a great choice.

Anker Power Bank

One of the better known computer accessory brands out there, Anker have a good range of different devices that can help assist you with your cable needs. They’re typically very well priced, and this is certainly the case for this Anker power bank.

This power bank has different ports on it you can use. It has a 45w USB-C port that you can easily connect your laptop up to. But as well as this, it also has two smaller 15w ports. These are better used for your smaller devices, like a tablet or a phone. You can recharge this power bank to full battery in just 3 hours.

Something else that this power bank has that many others don’t is a specific “trickle” mode. This enables you to slowly make the most of your remaining battery and keep your laptop going, whilst keeping your battery maintained at a certain level. This can be useful is certain scenarios if you’ve only got a little battery left.

All in all, if you’re looking for something reasonably priced but with enough charge to replenish your laptops battery life back to full charge, then this Anker power bank would definitely suit you.

Typically, laptop power banks are going to be a little bit more expensive than a regular bank you can use with your phone. This is because they require a larger battery with more capacity. But, you can still get some good power banks capable of charging a laptop for a relaitvely cheap price too.

This power bank is a good example of that/ Whilst it’s 19,200 mAh isn’t the highest capacity out there, it should be enough to at least recharge a 13 inch laptop back to 100% at least once, if not a little bit more than that. It’s a low cost way of doubling your laptops battery life.

It’s designed to be very lightweight and durable, and it’s aluminium shell will ensure that it doesn’t take any damage lightly. It will easily fit into your backpack, laptop bag or even into your laptop sleeve as it’s than small.

So, with the aluminium shell and quick charging time, it’s quite difficult to find another power bank that compares to this one within the same price range. It doesn’t have the same capacity as other banks, but typically they can cost double or more than this device. It’s great value for money if you’re after a budget power bank.

Common Questions about Power Banks

Are power banks safe?

There are a lot of questions around the safety of power banks, and whether it’s safe for you to carry them around in your rucksack. This makes sense, as you’d expect that a full charged battery may be a little dangerous. The truth is that in the majority of cases, power banks are very safe. If they’re made to a good standard, then you aren’t going to have any problems with your power bank whatsoever. However, the cheaper and lower quality your power bank is, the more likely it is that you might have issues with it.

How power banks work

Essentially, all a power bank is going is taking in a charge from the mains electric in your house (or wherever you charge it) and retaining this within the power bank itself. Then, when you plug a device into the port of the power bank, the charge will transfer from the bank into your device. Although this sounds quite simple, it actually relies on quite advanced circuitry to do this.

What is mAh?

When we’re talking about power banks, we generally use the unit mAh to measure the amount of battery charge it holds. This unit is the Milliamps Hours that the battery holds, which refers to it’s overall capacity and how long the battery will last. So in this case, more is better if you’re looking to recharge your laptop.

Can you charge a laptop with a power bank?

The reason why you can’t use smaller power banks to do this is that they’re generally made from use with phones. This means that their ports are designed to be used at lower voltages (usually 5v). This is why larger laptop power banks have one higher voltage port for laptops (usually 16-20v) and a smaller USB port for phones (5v).

Do power banks stop charging when full?

The good thing about power banks is that when you’re charging them, when they’re fully charged they’ll actually stop charging – this is due to the smart circuitry within the banks themselves. So, you don’t need to worry about them overcharging, and you can leave them on charge overnight if you need to.

Conclusion

In conclusion, getting the right power bank for your laptop is definitely important if your battery life is important for you. It can make a massive difference and double, or in some cases even treble the battery life of your laptop. This is important to those of us who are often travelling without easy access to a mains charger, and these are some of the best laptop power banks available for this purpose.
