Solar panels charge up fast and it’s very useful when u can’t charge fast and does last for long while love it I use it a lot

Great 10/0 always charged Free Solar I hope that you have a great day

Just what I needed to keep my devices charged outdoors

Not bad. Definitely good for camping. Used it for 3 days (Cell phones, portable fans) without needing to charge it.

Was awesome having this in time for the power outage.

The Anker Solix C300x is ideal for maintaining WiFi connectivity during power outages, and the ability to recharge using solar panels was a major factor in the purchasing decision. I am pleased with the purchase and glad to have a solution when the power goes out.

Expensive, no electrical outlets. It's just a giant USB charging battery with a built in light. You can do better in this price range.

Anker/Solix continues to refine the portable power space, this feature rich model is no exception. I have other portable power devices that go way back to lugging heavy sealed lead acid batteries encased in a wheeled suitcase style. These products have come ALONG way since those early days. You get 7 versatile ports in a neat space saving design. This ultra portable and ready for any adventure portable power bank will become a mission critical addition to any gear list. Unboxing was a breeze and this power bank came packaged with their rugged and outdoor rated solar panel. I did take advantage of the dual charging (140w) inputs to maximize the charge time and was fully charged in less than two hours from the out of box 20% charge. While it was charging I downloaded the Anker mobile app and was pleasantly surprised with how much info is shared. Battery temps, state of charge and individual details from all 7 ports. Pretty slick and the first Anker branded item I own that has this connected feature. I also appreciated the extension and adaptor that came standard with the solar panel, I will be able to utilize it with other Anker branded power banks. One random call out that I was not expecting was the clarity of the integrated display, the previous models had a very basic, limited display while this one almost seems like a lcd screen. I was able to verify that in direct sunlight performance is not impacted, but in a pinch you can also reference the mobile app for the same information and so much more. This model paired with the 60w solar panel, which will charge to 80% in approximately 4 hours in ideal conditions, can give you more than enough power on demand to keep all your devices fully charged. I have used this to charge laptops, cellphones, drones, bluetooth speakers, LED light strands, smart watches, and portable gaming consoles. This model does lack a 120v standard wall outlet but does have a slightly larger version available if that is a requirement. I choose this one and haven’t been inconvenienced. Build design and quality are typical Anker/Solix standards, smartly laid out and stout construction. They do highlight on their website the durability of the build construction. The two ways to carry this model provides options depending on the activity. The layout of the ports allow you to connect and utilize them all at the same time if necessary. The bonus pop up LED light will be used more than you expect and compliments this models Swiss-army knife utility. They claim this model is 30% smaller vs the competition when comparing same power storage capacity. I paired this with the accessory carry strap and feel this power bank can tag along for any hike or outdoor adventure. Anker/Solix has also integrated their “infinipower” technology which utilizes industrial grade components and smart temperature control to maximize and protect the lifespan of the battery bank. Overall, the design and layout of this power bank when paired with the packable solar panel provides you endless charging options for all your power hungry technology. This will become a constant when packing for any future adventures!

Just as I expected! Works for whenever I’m out and need to recharge my items!

Great power source to charge all your devices. Solar panel really helps if you lose electricity.

The best product I've purchased excellent would absolutely purchase again

There is a lot to like about this solar generator and power bank. It can charge up with solar, a car socket, or usb type c. The storage is large at 90,000 mAh. I like that there are many usb outlets on it and I really like the pop up light on the top. When I received this, the first thing I did was charge it up with a 100w usb c charger. It seemed to go very fast. A couple of days later I had a power outage and I was able to use this to keep a laptop charged up for work. The next day, power was back, but I charged the generator with the solar panels. This worked really well, much better than I expected. I wasn’t monitoring it, but leaving it outside in full sun, it was fully charged in just a few hours. The solar panels are light and thin. They also fold up quite compact. You could even strap the panels to a backpack, which is pretty clever. You could also charge it up with the car adapter. My only complaint is that it is pretty heavy. The straps do make it easy to carry, though. Overall, this has been great to use and the many charging options are great.

Awsome product solar charging is a new era!I can recommend to anybody!

I like Anker products, but not this time. The battery lasted 5 days after first charge, 3 days after 2nd charge, and only 1 day after third charge. I believe I received a defective battery. Unfortunately the exchange window has closed.

Anker's SOLIX C300X DC Solar Generator is a fine addition to camping and in my case, motorcycle traveling. It fits easily in one of the saddlebags of my touring bike and I have used it to charge my phone within the saddlebag while the phone is connected to my Bluetooth helmet allowing me to listen to music while crossing the deserts of California and Arizona! There is a built in pop-up light that provides more than adequate lighting in the dark of the desert when accessing my motorcycles trunk and saddlebags, which do not have built-in lighting, so this was a much used feature during stops while night riding. The output to the light is adjustable via a push-button to the right of the unit's power button. There are 3 settings of 1, 2 or 3 W(atts) accessed by pushing that right button 1, 2 or 3 times and indicated by a lit up indicator on the left of the small screen and time left using the light is shown on the right of the screen. Handy! This Power Supply is power packed and allowed me to charge my Dell Inspiron 16 7620 laptop 7 times before I needed to recharge the Anker. For reference, the battery level on my Dell was at between a low of 45% TO 60%. I was also able to charge my iPhone 14 (from a fully charged SOLIX C300X) on a daily basis for a full week of use with no problems. The unit weighs in at just over 6 lbs. but was easily managed by myself (I am a senior citizen!) with the included carrying strap. I carried it low on my bike in either of my saddlebags and again, it was a welcome addition to my motorcycle travels! When you are crossing the deserts there are still times when cell signals are weak or non-existent and that is when your cell phone will likely drain its battery searching for a signal. Having the Anker SOLIX C300X with me gave me peace of mind that my phone's battery was going to be up to charge regardless! On motorcycle trips I carry my iPad with me and the Anker easily kept it charged. I also used a DC Fan in my saddlebags to keep my phone cool while charging it as I toured on my motorcycle. The button to the left of the small screen is for activating the Bluetooth and Wifi on the unit. Press once: Turns on Bluetooth and Wi-Fi for app connection. Press for 2 seconds: Turns off Bluetooth and Wi-Fi. Press for 7 seconds: Resets Bluetooth and Wi-F Upon downloading the application for my iPhone, I used it to do firmware updates to the Anker SOLIX C300X. Easily done and highly recommended! Once connected to the app communication via your phone can be via built-in Bluetooth or you can connect the unit to your WiFi. I chose the simplicity and ease of Bluetooth but it is easily joined to my WiFi if that what I want to use! You must download the app to access the unit but doing so will allow the following functions: Turn the power station on or off. Adjust screen brightness. Monitor the remaining battery life and charging time. View output power and which ports are in use. Control the standby duration setting. Receive alerts for low temperature, overload, or high-temperature conditions. Perform firmware updates. During my testing I also fully charged the unit, shut it down and then waited 2 weeks to see how it held a charge. My results? After two weeks the unit retained a charge of 100%! That is outstanding! The Anker SOLIX C300X also comes with a Solar Charger but during my testing we had so much rain this was not possible for me to do with any degree of success but I will be using that feature in the future believe me! I cannot recommend this wonderful product enough! It really is versatile and easy to use and it will be going with me on my motorcycle trips throughout the coming years. It is that useful and easily carried in my motorcycle's saddlebags or in my car or truck! Highly recommended and a really outstanding product!

The Anker Solix C300X is a solid portable powerbank. I'm a fan of Anker products for phones and was excited to see how this power bank would perform. The C300X comes with a bevy of bells and whistles. In box you get a USB-C charging cable, detachable carry handle straps, folding solar panel, and dc adapter cables for the solar panel. The actual power bank can be connected to the Anker app to control and track battery levels and even has a built in lantern with adjustable brightness levels and is accordian designed so it can be opened upwards or collapsed down to adjust the amount of light you need. Its loaded with connection ports ( 2 x USB A ports, 4 USB C ports, and 12V car charger port) so you can charge up to 7 devices and be charged by 3. The included solar panel is foldable and easily stored, it is the 60W option and takes about 4-5hrs to charge (depends on weather conditions and sunlight). There are some pros and cons. I'll start with the cons, certain accesories should be included but aren't and will require you to spend more money. The solar panel is a 60W but Anker sells a 100W option which cuts charge time in half, idk why they dont make the 100W the default and only option as it is more efficient. Anker also sells the 12V car adapter separately which again should be included but isn't and requires you spend a little more money. These two reasons are why I took one star away. The Pros are that this power bank is excellent for travel or recreation use. The built in lantern is good for night activities, most of the USB-C ports are high wattage and will fast charge most handheld devices (phones, tablets, wireless headphones), and the solar panel is easy to store and transport so less clutter. I really wanted the Anker C300X for emergency purposes to keep certain devices charged like when heavy storms hit and there isn't power for days, but now I'm excited to try it out on fishing trips and outings. I would absolutely recommend the Anker Solix C300X.

Anker is a company that has made quite a name for itself over the last few years. Their battery packs, cables, and USB hubs are among the best quality products you can find. So, it only makes sense for them to be taking things a step further and building high-capacity batteries for camping and generators! Initial unboxing of the C300X the unit is solid but not too heavy with a nice black matte finish to it. There’s a clear and crisp display on the front that shows the battery percentage and the amount of wattage going to the device you’re charging. Out the box it does require a charge to get to full power. I was surprised that the battery doesn’t come with a USB-C power adapter. It does come with a USB-C cord but not having a proper adapter that can fast charge the device seems like a cheap oversight. The battery has a light on the top of it with 3 different levels of brightness that is very handy. The device itself has 5 charging ports. 2 of the ports are 2-way USB-C 140w for fast charging. There’s also a 100W USB C a 15W USB C and 2 USB-A’s. The device can charge through the car port and included are Solar Panels to recharge. You also can connect the battery to their app using Bluetooth that shows the remaining battery capacity and how much energy is being used by the devices connected. During testing I connected my Iphone 16 pro that was low on battery and was pleasantly surprised to see it only took about 3-5 percent of the overall battery on the C300x to fully charge my device. Plugging multiple devices in at once like a macbook, iphone and switch the battery handles it beautifully. I could see how this would be an ideal device to have camping or in a power outage as the Solar Panels will allow it to be completely portable. Even in a power outage the battery will last through the night powering all your electronic devices and then can recharge in the morning! I haven’t been able to test how quickly the solar panels recharge but I’m looking forward to using them in the future. Overall I am very happy with the performance of the C300X. The battery is portable enough to be a great solution for anyone who needs a battery on the go and would be an ideal for camping or power outages.

This is an impressive compact generator from one of the most reliable brands on the market for power banks. We use it often on our back covered deck when spending time outside. It's great for keeping a phone or bluetooth speaker charged during extended use. Guests love that they can top off their phones without having to worry, and the light on top adds a nice touch in the evening. Setup for the power generator itself is very straightforward. You'll want to plug it in and charge it to 100% before using it, and also download the Anker app so you can update the firmware. I'm sure you're thinking, "great, another app." Trust me, I get it. But the app is fairly simple to use and does allow you to monitor the unit and control the light remotely. More importantly, it's needed to get firmware updates, and Anker does not require a sign in to use it. I found the app useful, but it's essentially a digital version of the "dashboard" on the front of the unit. It was interesting to be able to see the output of each port in real time, and if you have multiple devices, you can create a whole system in the app. It's a nice feature. The solar panel, I haven't had a lot of time to test out, but it's kind of clumsy. It folds up into a tight square with a carrying handle, but it does have some weight to it. I view this as a nice tool for an avid camper, but that's really the only use case I can think of outside of a multi-day power outage. I don't know how stable it would be either. Even just setting it up inside the house it seemed like it wanted to fall over. If you are able to prop it against something solid, it's probably fine, but otherwise it seems like you would have to pay close attention to it to make sure it's still upright. Overall, it's a great power bank with nice features and companion app. Campers and people who like to spend time outdoors will love this, and it could come in very handy if the power goes out with it's ability to keep more than just a cellphone charged like most basic battery bricks. I definitely recommend it!

Overall, the Anker Solar Generator SOLIX C300 holds a long-lasting life. I had several charges from one full charge on this battery source. The charge to the Anker takes nearly 24 hours, but it goes a long way to charge all my devices. I didn’t try using both USBC ports simultaneously to charge the generator. There are several ports: 2 USBs, 4 USBCs, and a cigarette. I feel that there should be more charging ports for as large as it is. There’s a light at the top that is handy for outdoors - especially on a recent camping trip. There are 2 levels of brightness for the light. The Anker came with a solar charging panel that appeared to be very complex but was actually very easy to use. The solar charge was much faster than the electric charge (using only one USBC port). To my surprise, the solar method is preferred. The actual panels open up to cover a large area but condense into a notebook-sized, compact, easy-to-transport carrying device. Lastly, the Anker has a built-in (removable) carry strap that makes it easy to transfer from one location to the other. This is handy considering how heavy the device is. It weighs roughly 13 lbs. and makes my camping tote much heavier. If my camping tote didn’t have wheels, I wouldn’t travel with this Anker, although it lasts through several charges for several devices over several days. This Anker is handy, but not convenient. I also feel the value is lacking for the price.

This Anker solar generator can come in handy in several situations - planned or unplanned. It would be great to take with you camping, to the beach or pretty much anywhere you won't have access to electric power. There are various ports available (just read the specifications for the details) but the main thing that I feel is lacking is at least one AC outlet. If an actual outlet would've been included I think this would be at least a 4.5 star product. Once the generator is fully charged, I think one would be hard pressed to run the battery down - it really has that much capacity. The built in light is a nice feature to have whether you're outside and it's dark or you're at home but your power has gone out. One thing I wish it had come with was a carrying case - I think that would've been an excellent addition to the package and would really make me think Anker was being thoughtful in anticipating customer needs. However, that one minor gripe aside I don't think you can go wrong with this as long as you don't need an actual AC outlet.
