## Questions & Answers

**Q: Hi just a question which way should I hold the Power Bank to read the compass. Should the usb symbol be facing forward?**
A: Compass’s point the same directions regardless of how you hold them they run of magnetic forces.

**Q: How to turn the flashlight off**
A: The manual says to double press the power button. This is incorrect  JustJoan is correct 
Hold the power button down for three seconds 
To turn the flashlight on 
Hold the power button down for three seconds again to turn it off

**Q: How do I charge battery in this power bank**
A: When you are outside let the sun charge it or plug it in before  you go anywhere.

**Q: How long does it take for the  sun to charge pack**
A: Actually, according the the spec sheet the solar cell charges at a rate of 400 mAh at 5.5V. For a 34800 mAh battery (which this unit has) that would be 87 hours assuming it is tracking direct sunlight the whole day. If it is lying flat on a surface, it will probably get between 1/3 to 1/2 of that, which means it will take about 20 to 30 days for a full charge from zero. On the other hand, in 8 hours it would probably charge around 1600 mAh which is enough to fill up 80% of a cell phone battery (a 400 mAh deficit for a typical 2000 mAh cell phone battery). So if you fully charge the battery pack, it would take 87 days (34800 mAh/400 mAh almost 3 months) to run down the battery completely. 
The solar panel seems reasonably sized for charging small appliances.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Amazing charger
*by S***D on July 2, 2025*

Wow, this solar charger is absolutely amazing. It’s so convenient when I take my jet ski out and need to recharge my portable speaker. Once the battery starts getting low, the solar starts charging highly recommend.

### ⭐⭐⭐⭐⭐ Best choice!
*by C***L on June 15, 2025*

Best one I have bought. I purchased 4 different ones before finding this one. This is my third one I have bought to give to my daughter. Charging my phone is easy and efficient. I use the flashlight at night when letting my dog out to do its duties.

### ⭐⭐⭐⭐ Perfect for what it is, small, wireless charging, and reasonable price.
*by J***X on February 1, 2025*

There are a lot of reviews saying solar panel doesn't work, can only charge phone a couple of times ect...It's all about reading the specks and math.Solar charging:This device is small. It's length and width is smaller than my galaxy s22 and only slightly thicker. I can easily carry it in my pocket. Putting an led in line between the Solar panel and the battery to indicate current flow is a very basic circuit. If the led that indicates the Solar panel is charging is on, there is current flowing to the battery and it is charging. There are excellent explanations in the question section which do a great job of explaining the math and why it would take probably over a week to fully charge this device. One review I read said the device would not fully charge with Solar. I "capped off" my phone from about 50% battery to 85% which used about one "bar" or one of the indicator let's. I then put it outside in the South Florida sun, in direct sunlight to see if I could fully charge it with the Solar panel. It took 3 days. It finally got back to a full charge. Am I disappointed, NO, that's about what I would expect. If you wanted to fully charge your phone, then recharge using Solar, the Solar panel would have to produce the same watage over a few hours that you used to charge your phone. You can do this with one of the folding Solar panels Amazon sells. These panels are huge in comparison to the tiny panel on this unit. It's all math and physics. Hurricane Andrew back in the day, we were without power for a little over a week. Thus device would have charged my phone once or twice, then it would probably take a week to recharge. Not what this device was designed for."I can only charge my phone a couple of times before recharging"Thus battery is small and easy to carry. If you are comparing power banks using the same technology, same type of battery, more capacity equals larger battery. Again math and physics. If the battery bank is about the same size as your phone, you are only going to get around 2 or 3 full charges with it. A power bank is basically all battery, so if the device is about the size of your phone the battery size inside is probably 2 or 3 times larger than the one in your phone. Thus expect 2 or 3 charges. Again math and physics. In an emergency situation, I would use this as a Solar flashlight. I have a larger power bank that is about the size of a lunchbox with a large folding Solar panel to charge it. Under perfect conditions I can recharge that device in about a day to day and a half. I recommend this device as long as you understand it's limitations. Remember it can fit in your pocket, It has wireless charging, and is inexpensive.BTW, the compass is just a novelty. If you are putting yourself in a situation where you need a compass for navigation, carry a real compass.
