CPAP Power Bank Buyers Guide


A power bank being portable is an incredibly important factor that you have to consider when making the decision on if a portable power bank is the right choice for you.

Many things can impact a device's portable nature such as the weight and size but also if a device comes with a handle that will make it a lot easier to travel or move it around in general.

Many of the above listed products all are very portable and in some cases do have handles that you can use to carry it around. You should really consider this along with the size and the weight of the device.

Full Charge

With regards to a device's full charge you should consider this with the utmost importance due to the fact that it will be powering a CPAP machine which can help keep you alive.

The full charge is something that should be able to last a few days as you may want to take it on things like camping trips which would be an issue if the full charge were to only last you a few hours.

The longest charge on this list is 6 days which is a very impressive amount of time to still have a charge. This will obviously be impacted if you are using the portable power bank to charge multiple devices at once as they will require power too.

This is something that should be at the top of your priority list when selecting what is the best Portable charger for you.


The weight of the device is also incredibly important with regard to it being a portable device. This is because you don’t want to feel like you are lugging something around with you that could be weighing you down.

The majority of devices above are all very lightweight and will ensure that you are not weighed down by them when you are travelling with them. Obviously weight is not the only thing that makes a device portable but it is a big factor and should be treated as so.

Some devices will come with a handle so you can kind of give up some weight if you feel that the handle will be enough to make it a portable device for you. Like mentioned it is important and should be considered before making your final decision.


The size of a device is also incredibly important when it comes to choosing what is the best device for you to use.

Many of the devices above are all very small in stature and won’t take up lots of room when you decide to travel with them or perhaps place them in a corner of your room. Size is incredibly important just like the weight of a device is when it comes to if it is portable.

The reason for this is because you don’t want it to take up all the room in your luggage if you know you have to pack a lot of items.

Ideally the smaller the better but it you should take into account that if a device is a lot smaller you may be missing out on other features like multiple USB slots which can be used for other devices also.

Multiple Devices

This is a factor that should be left up to you to decide on how important it is. Many of the above power banks are capable of charging multiple devices at one time thanks to the amount of input and output slots that the device may have.

Specifically speaking you just want to make sure that it is capable of powering your CPAP machine but it is an added bonus if it can charge your phone overnight too.

Especially if you know that you enjoy camping and go to a lot of places that may not have a power source other than the one that you bring with you.

Digital Display

Again this is left for you to decide on the importance of this because it doesn't impact the power banks capabilities but it will make it a more user friendly experience for you especially if you don’t exactly know what you are doing with the machine at first.

If you have a better understanding of portable power banks then it may not be the most necessary feature for you.

However, if you know you will struggle to understand exactly what the machine is telling you then it is highly recommended that you select a product that has a digital display that can majorly help you out.

Frequently Asked Questions

What Is Considered A Good Full Charge?

Well really you at least want the charge to last you 8 hours based on the fact that on average that is how long people normally sleep for.

However, many of the above products can hold a charge for multiple days which can be incredibly important if you know you are going on a camping trip where you may not be able to charge the device regularly.

Is A Lightweight Product Really That Important?

Like mentioned it is up to you to determine if it is an important feature of a product however, it will help when moving the product around that it does not weigh as much as a tonne of bricks and won’t be weighing you down.

Does A Handle Really Make It More Portable?

I wouldn’t necessarily say more portable because you can still carry a device without a handle but it will make the whole activity of carrying it a lot easier for you.
