Overview of Beam Backpack
I recently created a post explaining the meaning of solar panel backpacks and because of that post, I decided to research on solar bags just so I could give a proper explanation by seeing them firsthand.
During my research, I stumbled on this bag and I have to say that the pack was pretty impressive. It had a nice look and its features were pretty good.
It was well padded and from what I found out the solar cells used for its solar capability are top-notch and are produced by one of the best companies around.
These obviously made me more curious about this back bag which is why I decided to write a review on it. In this post, I intend to detail out everything I found about this bag. Some points I would be writing about listed in no particular order are…
- The material used in designing the bag
- The type of solar cells used and the company behind its production
- The features of the bag such as its Voltage Regulator which helps to control the power input/output for charging your device, USB charging ports, RFID anti-theft protection, anti-theft buckle lock to secure the pack from thieves, and much more features
- The charging efficiency of the solar panel
- How to properly use the solar panel
- Some drawbacks of the beam backpack
By the time you finish this review, you should have a good idea as to whether this backpack is right for you or not.
The material used on this bag is polyester and it claims to be waterproof. While I am not doubting this, I would have to say that it is probably more in the water-resistant category.
This means that when exposed to light rain it would probably be able to withstand water from gaining access into the bag for some time but this can change if left under the rain for a longer period.
For heavy downpour, the time it would take to withstand water from gaining access into the bag would be shorter than that of a light rain.
On a positive note, the zippers used on the backpack is a YKK Water Resistant Zipper to keep any water at bay.
Design and Comfort
The beam backpack was designed for maximum comfort as it was made with a lightweight material. The back of the bag was designed with a thick soft multi-panel ventilated padding.
This creates a good airflow between your back and the back of the pack which would help keep your back dry.
The multi-panel ventilated padding also helps to give you maximum back support.
The ergonomic design and compression shoulder straps of beam’s backpack helps stabilize the weight of the pack on your lower back as suppose to a traditional pack which pulls down on the shoulders and concentrates its weight on the lower back.
It was designed with breathable cotton shoulder straps and you can easily adjust them so it better fits on your back.
To better fit the bag and make it more comfortable you can make use of the adjustable chest buckle which you can secure with the magnetic suction seal.
A complaint I found was that the bag absorbs a lot of heat being that it is black.
This can lead to a battery getting overheated when been charged and can lead to the battery going into an error state as the bag is closed.
Although I only found a few people that this happened to but just in case, the advice given to counter this is to open the top cell of the bag to let out the heat out of the bag.

Storage and Organization
Beam’s backpack was designed with 5 main compartments to make organization of your items easy. It comes with a laptop compartment capable of holding up to a 15.6inch laptop.
This is bad news for those that own a laptop with size more than 15.6inches because it would not be able to fit properly into the laptop compartment.
As good as this bag is, this can be a disadvantage for those looking to carry a bigger sized laptop and they might not be willing to invest in this bag because of this.
The solution to this is in making use of the main compartment to store your laptop.
By doing this it should be able to hold laptops that are bigger than 15.6inches.
This does come with a disadvantage as the laptop would not be properly protected as it would have been if it was in its own compartment which was specifically designed for it.
It also has a compartment capable of housing a 10.1-inch tablet.
It’s most spacious compartment is quite large to contain most of the items you use on a daily basis. It might not be as large as we might have expected but depending on your needs, it should be large enough.
There are also quick access pockets at the side of the bag for items like your water bottle, umbrella and similarly sized items.
The beam backpack has a reflective logo at the back of the bag which lights up when you decide to charge your phone with the backpack under the sun’s radar.
The logo lighting up indicates the bag is working and charging. It also lights up during the night if you decide to charge your device.
Beam backpack comes with two noticeable anti-theft features and they are
- Anti-theft buckle
- RFID blocking
It has detachable shoulder straps with locking buckles and they can serve as an anti-theft security system.
It allows you to be able to lock the buckle around anything which can help prevent the theft of your backpack.
All you need to do is to loop the strap, click the buckle and lock it up.
RFID blocking is meant to safeguard your data present in your credit cards.
This can come in handy as thieves now have ways whereby they can access your credit card information just by standing close to you.
To prevent or reduce this some companies now produce products that have RFID blocking.
For backpack companies making use of this, they usually create a special part of the bag mostly a pocket where you can place items like your credit card, passport or similar items.
When these items are inside these special pockets they become inaccessible by anyone trying to steal the information in them making use of technology without actually opening the pocket.
I am not entirely sure if hacking this is possible but at least it gives you a better chance of beating the bad guys.
Beam backpack comes with an RFID blocking feature located in a side pocket at the side of the bag.
The pocket is made of a double layer silver fabric, magnetic suction deal which offers 99.99% protection all held within a slim band.
Flexible Solar Cells
Ever heard of CIGS? The full meaning of this is copper indium gallium selenide solar cell.
It is actually a thin-film solar cell that is used to convert sunlight into electrical power.
It has a high absorption coefficient which means that it is able to strongly absorb sunlight.
One of the most popular American companies that produce these sought of solar cells is Miasolé. They are an American solar energy company that sells CIGS thin-film photovoltaic products.
Their manufacturing process lays CIGS on a flexible stainless steel substrate.
They are behind the manufacturing of the CIGS flexible solar cells used in the making of beam backpack.
One very important fact you need to know behind the technology of this type of solar cells is that they have a conversion efficiency of 19.2%.
This might not seem like a big deal to you but trust me when I tell you that it actually is a big deal.
It is a big deal because It sets a world record for CIGS sputtering technology.
It adheres directly to surfaces and is very lightweight, ultra-thin and flexible which makes it an excellent power source for a solar panel backpack or a solar-powered pack.
The Miasolé Solar Cells boast a 5V-11V; 0.1A-1.7A peak charging current giving you an easy way to charge your cell phone using the sun’s energy while on the go.
USB Charging Ports
A solar-powered backpack would be completely useless if it doesn’t come with a USB charging port for connecting your cable to power up your devices.
The beam backpack comes with unique USB ports. This would be very beneficial depending on your type of cable.
It has one USB output charging port along with a micro USB charging port. Some USB cables are made up of the normal sized charging connectors while some others are small sized.
So depending on the size of your charging cable it should be able to fit either into the USB output charging port or the micro USB charging port.
It is advisable that when making use of solar energy to charge your device that you make use of a voltage regulator.
A voltage regulator helps to control the power input/output for device charging.
If you intend to build your own solar panel backpack you might not have any idea about the amount of energy the panels you get might produce when charging your device.
It is best to get a voltage regulator that can help to control this current so you don’t blow up your device.
The voltage regular included in the beam backpack as I mentioned above helps to control the power input/output for charging your device. It gives optimal and intelligent charging.
How exactly does this work? Well, let me explain. The power supply for older solar power technology is usually limited when there is a cloud cover.
What the beam’s voltage regulator does is that it automatically reboots when this happens which gives you a continuous power supply without a manual restart.
It automatically identifies the sun’s strength and exposure and automatically switches to solar power and self starts without human intervention.
To better understand how to use this please follow the principle of operation below.
Solar Charging Efficiency
The solar panels used in the production of beam’s backpack were tested outdoors to show you just how well they work and the results are documented below.
Note that the solar radiation was about 1125W/m2 and it was tested with direct sunlight.
Also, I was able to collect these results from the sales page of beam’s backpack so I have no way to know if they are accurate.
- 8.5 hours get a 10000 mAh power bank fully charged, 4.71-5.0 Voltage maximum 1.35A of electric current
- 3 hours get a 2716 mAh iPhone X fully charged, 4.71-5.16 Voltage, maximum 1.27A of electric current
- 3.5 hours get a 3400 mAh MIX2S fully charged, 4.71-5.17 Voltage, maximum 1.32A of electric current
Been away from home can mean that you would have no power source and a dead battery can make life difficult for anyone that regularly makes use of their phones.
Accessing the internet, making that emergency call or even taking that memorable picture can be difficult with a dead battery.
Beam’s backpack is a way to stay fully charged because it is a solar powered backpack.
It has an ergonomic design, is highly water-resistant and is able to attain a peak output current of 1.7amps making use of one of the most powerful renewable natural source of energy which is the sun.
Its solar cells which are CIGS are considered to be one of the best in the world. They are lightweight, flexible and are waterproof.
Your devices are sure to remain powered and your items are sure to remain organized due to the organization pattern of beam’s backpack.
Its exterior storage system is as organized as its interior storage system making accessibility easy enhancing its user experience.
It’s charging speed and efficiency is close to that of charging indoors with an outlet.
The buckle of its shoulder straps can serve as an anti-theft protection system that can be used to protect the backpack from being stolen.
Although the laptop compartment might not be as large as I might want, it is still a backpack that I highly recommend for anyone looking into solar powered backpacks.
