About Us
In recent years, with the popularity of smartphones and various mobile electronic devices, founders Bard and Daniel have increasingly noticed the anxiety of mobile device users about battery life. So they founded the brand "Mregb" in 2014.
Mregb's core purpose is to provide users with high-quality,gendurablemost cost-effective power banks,addressing user concerns about battery power.

Product Description
Perfect compatibility
The product has a built-in smart chip that can automatically identify all USB devices on the market, and then change the voltage and current to make it compatible with different devices (such as iphone, Samsung mobile phones, tablets, cameras, etc.)
|
|
|
|
|---|---|---|
Safe large-capacity batteryThe product uses a safe and reliable high-density lithium polymer battery, which is smaller in size and has a larger battery capacity. The built-in security chip stabilizes the voltage and current and controls the temperature, provide safe protection for the power bank. |
A convenient and easy-to-use compassThe compass is precisely calibrated before it leaves the factory. It is built into the solar power bank without additional carrying. Point out the direction for you outdoors, so that you no longer get lost. |
LED indicatorThe LED indicator can accurately display the battery power, which is convenient for controlling the battery power during use. |
|
|
|
|
|---|---|---|
Two charging methodsThe product has a solar charging function, but due to the huge battery capacity and the limited charging power of the solar panel, the actual solar charging speed is very slow, and it is only used as an additional emergency function in emergency situations. In normal times, it is recommended to use a charger above 5V2A to charge the product. |
Waterproof/drop-proof/dustproofThe product has the top protection level of IP67. And use high-strength ABS material without fear of falling from high altitude. It can still work normally in extreme environments. |
FlashlightThe flashlight can stay on for more than 80 hours. In an emergency, which may help you get out of trouble.Note: (Long pressing the power button for 3-4 seconds,flashlight turn on, long pressing again, flashlight turn off. ) |
Rich application scenarios
solar power bank special Design for Outdoor. Compact design and with a hook + Carabiner, so you can freely attach it to your backpack in camping, and it will recharge itself under direct sunshine for emergency.
There is electricity when there is light
Specification
- Battery type: Li-polymer battery
- Solar panel: 5.5V/400mAh
- Material: ABS+PC+ Silicone
- Input: 5V/3A
- Output: 5V/3.1A
- Charging time: 8-10h
- Operating temperature：-10℃~+60℃
- Battery life：1800 charge and discharge cycles
Owning this equipment allows you to travel, travel or work, whether outdoors or indoors. Get rid of the anxiety about electricity anytime, anywhere.
Due to the extremely large battery capacity, the charging power of solar panels is limited, the intensity of sunlight and the instability of the length of time each day will affect the power of solar charging, and solar charging is very slow. Therefore, the solar charging function is an additional function for emergency use in emergency situations, and cannot meet the charging needs of daily use. It is recommended to use a charger above 5V2A to charge this product.

ATTENTION: Most of the bad reviews are because of the charging time under sunlight, this charger was not specifically made to be charged from the sun, its main charging method is to be charged from the wall.
Overall I am very happy with this solar charger, I charged my Motorola g7 play a couple of times, my portable Bluetooth speaker, and my AirPods. the battery holds a lot of charge. its really sterdy and compact.
My family ran a firework stand on the fourth of july and we needed to charge our ipad, this little charger charged the Ipad for pretty much all day (in one charge).
The flashlight is fairly strong, it was better than most of my familys other flashlights when i compared them one night, easily better than any $15 flashlight.
The usb ports were a little funky at first, one of my cords wouldnt charge through it, but you just needed to press it in a bit harder than I origonaly thought I woiuld have to.
PS: the compas was pretty usless, just spinning in circles over and over :/

It is approximately 4200mAH capacity instead of claimed 36800 giving just 11% of claimed efficiency!

I got this intrigued by the battery capacity in a small form factor that could have been a great option to travel with. Solar charging is an additional feature too that could be very useful in situations when you are outdoors and there is no other AC power source to keep it charged. The very first thing I did is to fully charge and measure the capacitance (mAH) of these. I was really disappointed and would not recommend this product that is very reasonably priced but internally it is false marketing with higher numbers to disguise consumers.Reviewed in the United States on September 20, 2022
My 2 cents are below:
Pros:
- Can charge multiple devices simultaneously
- Solar charging is a key feature but in my experience, it charges very slow & I ended up charging with a wall charger
- IP67 is waterproof and feels rugged overall
- Dual LED flashlights (680 lumens) are a nice addition to these
- Compass on the back of the power bank can be useful while outdoor recreations
- One of the slimmest & lightweight solar power banks in the market
- LED indicators in the device are very useful
- Very reasonably priced for the features it offers
Cons:
- On my tests ( I ran twice), this power bank only gave output capacitance of approximately 4200 mAH instead of claimed 36800 mAH. That's just 11% efficiency. I used a multimeter tester and a load with 2A power needs to test these (Results attached). These are really disappointing numbers & I believe battery capacity is false marketing being done for this product
- No fast USB-C PD (18W) charging in these
- No mention of safety standards like battery overcharge protection, overcurrent protection, output overvoltage protection, temperature control, short circuit protection, etc anywhere giving me less confidence in these
- Not a very great build quality. It feels plasticky & does not feel premium. Even the port cap fell off while using it
- Mismatch in use of manual directions. They say double click power button for flashlights but it works with a long press instead
- Came in generic packaging without any branding
- I wish a travel pouch was included that would have made it so convenient to carry along and I believe that this should be a standard across all other brands too

The shipping was fast, the item looked exactly as pictured. I charged it overnight and when I plugged into my phone it said slow charging. The flash light works, it’s a handy feature . Did not test the solar charger feature. I was looking for a fast charger so I will return the item and look for another.
