Power banks come with all sorts of charging features, such as having low or high capacities and different charging speeds, and they can also have different designs. How you recharge a power bank is one of the most vital parts of owning one because you want an accessible way to recharge it. In this review, we’re looking at this IEsafy 26,800mAh solar power bank.

Built-in solar recharging for a power bank sounds incredible, but let’s see how it performs and what other features this IEsafy power bank has.


Power Capacity:

This IEsafy power bank has a 26,800mAh capacity, and that’s a lot of power. With a 26,800mAh capacity, you can charge most phones to full power about four or five times. When it comes to charging, higher-end phone models such as the Samsung Galaxy S22 Ultra, which has a 5,000mAh battery, or the iPhone 14 Pro Max, which has a 4,323mAh battery, can charge to full power about three times with this power bank because they have much larger batteries.

For charging tablets, you’ll be fair about one or two full charges, and for laptops, well, you can’t charge laptops with this power bank as the ports don’t supply nearly enough charging power, and there aren’t even any USB-C ports on it.

Output Charging:

The output ports could use some work on this power bank; however, the ports are alright for the price and the built-in solar panels you’re getting with this unit. That said, we still think that the lack of fast-charging ports is a big flaw, as nearly all portable phones and tablets are compatible with some sort of fast-charging technology.

So the two outputs are two USB-A ports that each have a 5V/2.1A (10W), and the max output of the power bank is 5V/2.4A (12W). So if you’re charging a single device from one of the USB-A ports, then you can use the 10W from each port, but if you’re charging two devices simultaneously, then the 12W max output of the power gets split. Raising the max output to about 24W would have been better to make the most of the standard charging that this power bank features.

Unfortunately, there are no USB-C ports on this power bank.

Input Charging:

You have two options to recharge this power bank: either use the Micro-USB input port or depend on the solar panels to solar recharge the power bank. The fastest way to recharge this power bank is to use the Micro-USB input with a 10W or higher wall charger. Yes, this power bank does indeed use a Micro-USB input directly charged from and not a USB-C port.

The main reason to get this power bank in the first place is the four solar panels on this IEsafy power bank. The solar input of this unit is 6W, and that’s not a very fast speed. Still, if you’re looking for a power bank that can recharge without a wall charger, unfolding panels is quite nice because you have more sunlight hitting the panels, which leads to more constant charging rather than just having a single panel.

If you’re camping or hiking and want a power bank that can charge without a wall charger, this IEsafy is a pretty good choice, but know that you’ll need a long sunlight exposure time for the panels.


Size and Weight:

When the solar panel is folded, this IEsafy power bank has a 6-inch length, a 3-inch width, and a 1.5-inch thickness. When the solar panels are fully unfolded, this IEsafy power bank has a 14-inch width. The charger weighs about 1 pound. So it’s possible to take this power bank anywhere with you.

Functional Components:

When using this power bank, the charging ports are under a covering, including the two USB-A output ports and the Micro-USB input port. A power button off to the side can be pressed to begin charging, showing the remaining capacity via the blue capacity indicators at the front of the power bank.

Also, the power button activates the flashlight at the back of the power bank; hold down the button to turn on the flashlight. The flashlight has three settings: constant on, SOS, and flash mode, which can all be cycled through by pressing the button.

Structure and Material:

With the charging ports covered, this power bank has an IP65 water-resistant rating, which means it can withstand water splashes. It cannot withstand being submerged in water and will get damaged if done so. The overall build is good and feels like a solid product; however, be careful not to treat the foldable panels too roughly and not to damage the connections to the power bank.


There’s not much to stay about the tech build of this power bank, as it doesn’t even feel warm when it comes to charging devices because the output is only 12W. The charger will get warm when you solar recharge it, but other than that, we didn’t find any technical build concerns.


This IEsafy power bank is not reliable if you’re searching for a power bank with fast charging, like, at all. It does not feature fast output charging for your devices, and neither does it feature fast input charging. Those two things are big deal breakers for consumers looking for a power bank.

This charger has solar recharging and a high capacity that can last quite a long time when it comes to charging phones. The solar recharging aspect will be most reliable if you can use the sun to recharge the unit.

The 26,800mAh power capacity is pretty good for charging phones to full power multiple times, but the charging ports could use improvement. This power bank does not feature fast charging for the output or input ports. Solar recharging only maxes out at 6W of input power.


The foldable solar panels are a great design choice, and there are power indicators for the capacity and the solar recharging—also, a LED flashlight with a few settings at the back of the power bank.


The build quality of this power bank is good but nothing too special. Just be careful about not treating the foldable panels too roughly, as that could damage teh connections. When you have the ports covered, this power bank has an IP65 water-resistant rating which means that it can withstand splashes of water but cannot be submerged in water.


If you don’t mind the lack of fast charging, this is an alright power bank, but we recommend purchasing it while it’s on sale.

The IEsafy is somewhat of a relic at this point. The lack of any fast charging ports at this point is a big letdown in an era where nearly every portable device is compatible with some sort of fast charging tech.
