YELOMIN Solar Charger 20000mAh Portable Type-C Solar Power Bank with 4 Cables Waterproof Battery Pack Outdoor External Backup

I'll start by saying this power bank is big and durable. It is perfect to take on long hike or camping trips. It can charge my phone multiple times to full with one charge of the power bank. The solar panel also works really well and automatically starts charging when it detects sunlight. The hand cranking is also a great add on which makes me feel much safer in case I am out where there is no charging available. The included cables also makes this a all in one where I don't have to worry about taking anything else. The wireless charger also installed works really well and is also a magnet so works perfectly with magsafe. It is durable and I feel perfectly safe just throwing it in my backpack when I am about to leave. The only thing to keep in mind is the solar panel and hand cranking charging is very slow. I would think it would be something you should only use in emergencies. I put the power bank in front of my window for about 3 days and it didn't gain too much. However, this is expected. In all, this product is amazing and I feel much safer having this when I go on long road trips Read more

I bought this YELOMIN Solar Charger 20000mAh Power Bank mainly for travel, but it truly proved its value here in Jamaica after Hurricane Melissa. With no electricity for days, this solar power bank became a lifesaver. On a full charge, it topped up my phone to 100% multiple times, and with sunlight during the day, it kept itself going enough to last me around three days before needing a complete recharge. The built-in cables and multiple USB outputs make charging different devices very convenient. The LED flashlight is bright and helpful for night use, especially during power outages. The device feels durable, waterproof, and well-made — great for camping, hiking, outdoor travel, and emergency preparedness. Just keep in mind that the solar charging works best for slow, steady topping up, not full fast charging. But as an emergency backup power bank, it does exactly what you need. For travelers, campers, or anyone dealing with storms or unpredictable electricity, this is a very reliable portable charger. Highly recommended for: emergency power, hurricane season, outdoor activities, travel, and everyday backup charging. Read more

I havent seen any electronics this well-made in years. Very easy to use. I like things that functional & made to last- my feeling is the crank should have been made of something sturdier than hard plastic (so 4 stars not 5) but having a crank & being so well-made (truly heavy-duty) & user-friendly puts it well above the rest.

This is a nifty handheld power bank. It has three charging inlets: solar, AC connector, and crank. These mean you have your phone recharging needs, and other compatible devices, without worrying about a lack of connection to energy sources. It comes with the following: 6 Ports Highly Compatible with Multiple Devices: The solar-powered charger has not only 2 built-in output cables (iOS & USB-C ), 3 output ports ( USB*2 & USB-C*1), and a wireless charging area, but this portable charger supports charging 6 devices simultaneously. It has a 1 USB-A input cable and 2 input ports (Micro & USB-C), and it offers five charging modes. Built-in 5V/ 3A USB Outputs make charging 6 devices at full speed easy. The wireless powering area has a magnetic pull, so your device does not slip off while charging. The power crank is a feature that makes such power banks great. You are never without an input energy source when out and about, and we all have been through it: your device dies or is at 0.1% power. Having this handy pack saves digitally infused lives. Its size and weight speak to in-car, travel bag, or backpack carrying, not pocket; you will want something smaller and lighter for pocket convenience. I also use it as an around-the-house power pack for all the little USB-powered devices (small desk and table lamps, rechargeable flashlights, portable radios, and so on). In addition to these handhelds, I also use larger power banks to run certain small appliances and space lamps; lots saved on the home energy bill. Nice and convenient to own. Read more

This device works as a powerbank and thats it. This device will quickcharge your phone, which is nice. The flashlight feature "DOES NOT WORK". The "on" button doesn't do anything either, and appears to be "purposefully" broken/disabled by the manufacturer. The hand crank ignites the led charge indicator telling you if you are cranking hard enough on a scale between 1 led to 4 led lights. THIS IS GOOD, but I can't tell you if this works properly, who is going to crank this thing for 4 hours straight? If it is a real emergency, you will probably be dead by then. But my guess is that it actually does work. Anything that lights up little LEDs is a good sign. The solar panel appears to work as the LED charge indicator does show up if you walk outside. How long this thing can hold a charge sitting in a hot car for months, well, that goes past the return date, so I can't tell you that. So in summary, don't use it as a flashlight, cause it doesn't do that at all, but your phone has a flashlight on it so whatever. I thought about exchanging it for a functioning unit, but amazon wants to charge 9$ to return a defective device. Thats 20% the cost of the device. Wrap your head around that. :( Amazon's idea of "free return" is that you buy a printer, put a label on the box, then burn gas and drive a 20 mile round trip (if you own a car) to a ups drop off location. Yea free, but yet not at all, not in the slightest. Just let it be known, the device is always on, as is all rechargeable devices, and it will trickle drain eventually, I would give it 1 month in my car. Then charge it once per month. Can it survive an EMP attack? Yea, if you put it in a lead box, it should be fine. Is it waterproof? Heck no, but keep it in a zip lock baggie (gallon size) in your trunk and it should be fine. Am I super awesome? Well yea, I know I am, and I hope you are too. :) Read more
