Solar charging is one of the most helpful types of methods of charging that’s available today and that reason for that is because these chargers are able to provide a portable charging experience that doesn’t really rely on a power capacity.

Sure, solar chargers need light for them to be powered and to charge your devices, however, as long as you have light hitting the Solar panels you’re able to use the solar charger and not have to worry about using a power capacity that will eventually deplete.

Another thing about these Solar charging is that it’s implemented within a lot of products such as power banks, houses, and even cars.

In this case, Solar charging is present with this Eceen 74W Solar Powered Backpack. A backpack that uses a Solar panel is one of the best innovations and this Eceen backpack is able to prove that with the power that it brings and also the design features that make it great to use.

Power Capacity:

Okay, so the Solar charger itself does not have a power capacity but the backpack does come with a power bank so we’re going to be going into detail about that and the Solar charging itself within this section.

The power capacity of the power bank is 10,000mAh and it’s important to know that it’s only the initial capacity of the charger. Since there are two USB ports on this power bank with one USB port having a charging speed of 5V/2.0A and the other port has a speed of 5V/1.0A.

Ultimately, the Output power capacity is going to vary depending on how you’re using the charger but the speeds aren’t breaking any records so you’re going to receive an average conversion rate most of the time.

Power for Smartphones

Most of the time you’re going to have 7,400mAh of Output power capacity that you’re actually able to use and that is pretty good. It’s with this power capacity that you’re going to be able to charge smartphones multiple times to full power.

As an iPhone 7 with its 1,960mAh battery can charge to its full power about 3.5 times. Or a smartphone with a very high battery capacity can charge a Google Pixel XL with its capacity of 3,450mAh about 2 times to full power.

Power for Tablets

Charging tablets with this Eceen power bank is also possible but you’re mostly going to want to do it with Mini tablets such as an iPad Mini 2 or an iPad Mini 4 because they have low power capacities and are able to charge to full power and at least leave a little bit of power left over.

Charging a full-sized tablet such as an iPad Air 2 will result in using the entire power capacity that the power bank has.

Output Charging:

There is two Output charging speeds that you need to consider when it comes to the Eceen 7W Solar powered backpack and that would be the Output charging speed of the power bank and the charging speed that the Solar panel offers.

Power Banks Charging Speeds:

The power bank has two USB ports each of the ports has a different speed. One port has a charging speed of 5V/2.0A and the other port has a charging speed of 5V/1.0A. You’re going to want to use the 2 Amp port first because it’s the one that gives a faster charging. You should only use the 1 Amp port for when you’re charging two devices at once.

One of the best parts about the charging speed when it comes to the power bank is that the Max Output of it is 3 Amps.

Solar Charger Speeds:

The Solar panel of the Eceen backpack has an Output of 7Watts and let’s take a look at the conversion below of Wattage:

7W /5V = 1.4A

The Solar panel charging method using just a single USB port and if you’re charging anything with it then it’s only capable of charging it at speeds of the 5V/1.4A.

This means that you can directly charge your smartphone, tablet or any other USB chargeable device with the Solar charging method. A charging speed of 5V/1.4A isn’t too bad and it’s not too great either. It’s going to charge smartphones quite noticeably if the charging speed is kept constant.

Also, this charging speed of the Solar panel is going to be quite helpful for when you’re recharging the power bank because the max recharge rate the power bank is 5V/1.0A so the Solar panel is able to recharge it at its max power.

Input Charging:

The max recharge speed of the Eceen power bank is 5V/1.0A via a Micro-USB Input port and you can recharge it at its max charging speed if you’re using a 1 Amp USB wall charger or higher or by using the Solar charger to recharge it.

You’re able to hold it in a single hand if you really want to or you can place it into the backpack as there’s a spot that’s built for it.

Functional parts of the Power Bank:

All of the charging components of the power bank are on a single side and that’s where you’re going to find: two USB ports and the Micro-USB Input port for recharging. On top of the power bank is where there are 4 Blue LED power capacity indicators and the power button.

Functional parts of the Eceen 7W Solar Powered Backpack

The Total capacity of this Eceen backpack is 42L and it has three zip pockets that are able to fit a total of that much stuff.

The first large zip pocket is where the 2L Bladder bag for water goes, and it specifically goes into a small pouch and you can place and attach the water bladder on the inside where there are two hooks. The water bag uses a sipping tube that is going to be very helpful to use when you’re on the move while hiking and want some hydration.

Then the other two small zipper pouches are great for putting any of the small things that you want to be able to find quickly.

The Panel has a small pouch at the back of it and that’s where you can find the USB port for the solar charger and that’s where it’s best to place the power bank because it’s easy to access it then.

One of the main reasons that you’re able to have a great experience with this Solar backpack is because it has recurved shoulder straps and hip belt features perforated EVA foams and that basically increases the comfort level of the backpack.

As a whole, it also allows lots of ventilation to pass-through the backpack so you stay cool even when you’re moving for longs periods of time.

One of the weak spots of the backpack is that the hip belt pocket is too small to really store anything too large and the best thing that you can do is to just place a water bottle on them.

Another thing to know is that the power bank that it comes with can also be waterproof because it has a covering that makes it waterproof.

The solar charger portion uses 2 Pieces of Monocrystalline solar cells that are highly efficient and are able to offer a conversion of energy that is 22%.

Tech:

On the tech side of things, everything is really good with the Solar charger portion not heating up during usage and the power bank itself uses all the necessary safety tech features to keep charging safely.

Reliability
