Customer Ratings & Reviews

My business requires me drive a lot to visit my clients. This excellent power station always make me a peace of mind on my electronics when I am on the road. Other than those bulky and chunky pieces in the market, it has excellent design and light weight. The USB C power delivery port is a fantastic feature which turns to an easy charge for my iPhone, Mac and Apple Watch. I would highly recommend Fremo as a productivity powerhouse!

This product is something I've wanted for so long, but never knew existed! This power station will keep my phones and laptops charged , and the built-in light is a very nice touch for camping! Key features highlighted were very easy to carry, relatively fast charging, 100W PD output - plus the standard AC, 12V, and USB Quick Charge outputs. The Fremo fit all of these plus the lithium battery is an advantage for a unit that will get cycled many times a week. I am more than pleased with this purchase and would recommend to everyone that looking for the first power station.

I hate long reviews, sorry in advance, but worth the read. Please note I got this unit on sale for $200 out the door. 1- Charging: I have charged this time from 0% to 100% a few times and recorded it, it’s just under 5 hours to from empty to full, [about 25% charged per 1.25 hours (75min)] – this is with the 60W charger input, not sure for solar panel charging if the output is less than that. 2- USB A & C There are two types, USB 2.4V & 3.0V. The 2.4 V works great to power other LED lights and charging other non-essential items. The 3.0V quick charge ports do quickly charge my phone just like my wall converter from Samsung so that is nice. Charging Samsung Galaxy S24+ from 0% to 100% takes about 5% from the power bank when the phone is off, a little over 10% from the bank if the phone is on so you get about 10-20 chargers on a phone if you did nothing else. 3- Pass Thru Charging: Fremo has stated “Yes, our product support pass-through charging.” I have not tried this out yet as having it plugged into a wall and then running something else seems like a silly test but if you had solar panel or a wind turbine plugged in it would charge while outputting which I think is nice. Just have not found panels yet I want to buy. 4- LED light: LED on the front has three modes (solid, blinking, SOS) and draws about 1W, this I ran for about 3 hours with nothing else plugged and it dropped about 1%. I’m figuring you could run just the front LED with nothing else for about 600 hours (25 days) which for emergencies if this was all you had is something to say in itself. 5- AC vs DC The AC power drains this much quicker than the DC does, the output is measured in Watts no matter if it’s DC or AC, but the AC converter inside does take power to run so you lose a little bit of the efficiency factor there. Ran a crock pot on high at 200W draw and you could count down less than a minute (45 seconds) for every 1% the power bank dropped. So you could run 200W output for a little over an hour, but this is where I think you need solar plugged in to get what you need out of this. Box fan on high drew about 65 watts, Laptop drew about 80watts when on and running, just to give you an idea I graphed this out: Charge time ~ 5 Hours At 1W ~ 600 Hours At 10W ~ 20 Hours At 25 W ~ 8,25 Hours At 40 W ~ 5 Hours At 65 W ~ 3,25 Hours At 80W ~ 3 Hours At 100W ~ 2,75 Hours At 150W ~ 2 Hours At 200W ~ 1,25 Hours Over 200 W ~ >1 Hour *Biggest note if you are drawing 40watts or more you are going to have less than 5 hours of running time, see the graphs I made. Cons: 1- Only real con I can see is the screen always stays on, it’s probably very low power consumption vs what’s plugged in so probably not notable but since you can’t turn it off without powering off the bank it would be hard to know for sure how much it pulls. 2 – Rubber dust plug cover for the dotted outlined areas around the plugs, not sure why just the cigarette port had a cover but if these get used for camping a cover sheet to keep water, dirt, and bugs out would be nice. 3- I like the strap handle, just would be nice if this came with a small waterproof bag that fits this and the charger nicely and power bank in it since the charger is kind of bulky, also nice to store it safe bag.

After researching on this product and read other people’s reviews I decided to give this one a try. After using it for a month I’m very happy for the purchase. I really love the design and the quality of this product. Specifically the leather handle are very sturdy and soft on my hands. The mat finish looks great. The navigation panel are separated by 3 sections and very easy to use. We used it for our camping trip to charge 2 phones, camera, and cooking. It is very reliable. Overall, I think this is a great product that I feel comfortable using it for outdoor adventures.

This battery pack has been fantastic. Powered ten 50 foot strings of christmas lights for 6 hours. Powered a diesel heater for tent camping for 2 cold 35 degree nights. Charged easily with a 100W solar panel connected directly to the battery. I look forward to seeing what else this can power!

As a camper myself, I have been looking for a portable charging station that I can carry around easily to juice up all my electronic devices. I had to shop around but never managed to find the right one, either because of size, lack of charging outlets or how compatible it is with all my stuff. I have an action camera, a drone and an air bed in my tent besides regular devices like phone and laptop. The Fremo X300 satisfies all my needs. This bad boy also makes it much easier for car camping as it charges my mini fridge and fits right under the backseat. Love the screen, easy to read. Lastly, the PRICE is UNBEATABLE! Highly recommend it!

I am a contractor. My car is my office. In my opinion, the best thing about this battery generator is, (other than charging my phone, laptop and printer ) I can use it to make hot coffee or oatmeal or instant noodle when I am on the road. I normally just pair it with one of those Travel Electric Kettles on amazon. the 300 watts kind. Don't think you can use it with any high wattage devices. I use the battery to power the kettle to make hot water. Then I made my own coffee. I don't have to wait in line for Starbucks. That saved me quite a bit of time and money. I have used this battery for almost a year now. It is still running alright.

This power station is great for people who want to make sure they can charge and power devices if the power goes out. It’s also great for camping. It charges to full in less than 2 hours. I also bought a solar panel that can charge it in about four hours! This is a great buy, but I think it’s worth $200-$250. I wouldn’t pay regular price for it. Sales happen often so keep a look out!

I has used this when hurrican beryl hit houston. I was out of power for 5 days and the fremo held me down. What makes this power station differnent from others is that you can monitor how much watts are being consumed and you have multple ports for your various gadgets. The circuit built is fairly strong. During a power outage I could power my modem/router so i could have widi and charge my phone. I would not use this for high power tools ( hair dryer or microwave).

Very compact. It powered my Starlink satellite, phone and laptop. I stopped it after about 2 hours but it had more use available had I needed it. I have charged it with the solar panel in under 3 hours and dual charged it with c port and wall outlet in under 2 hours and so far I am very happy with it.

Perfect small portable battery for me! I primarily use it to power a 43" tv mounted to a rolling tv cart so that I can watch sports on my back porch while in the pool.

Solid build quality, love the convenient flashlight. Looking forward to camping with it. I kept the styrofoam and used it as a frame for the faraday cage i made for it with the addition of some hvac tape. Works like a charm.

It was very good keeps charge and does what it's supposed to do add a reminder

I love this so far it’s there in case of emergencies. I tried it even when I had power and it lasted longer than I thought.

Great product built with compact size. Charges my 5 gopros at once on the go with the ease. Worth the price.

I see more and more of these portable chargers coming out. Up until now, I've only had the opportunity to use the small cell phone sized battery packs. Having a power station like this really offers a lot of great options, and this one comes with a huge amount of features. This is a really nice looking portable power station. The case is laid out well. Markings are clear and readable. I like the use of color to help group and identify the ports. It's surprisingly light (about 8lbs.), When I saw pictures of it I expected it would weigh as much as a car battery, but far from it. There's a nice leather handle on the top that allows plenty of room for your hand. It was nice to see a handle like this, I haven't seen anyone put a leather handle on, well... anything, for a lot of years. It adds a touch of class and reminds me of when things were made to last. Hopefully, it will mean the same for this power station. The case has two ports at either end, one is for air intake and the other is an air outlet. There are actually fans inside, so cooling at some point may be needed, but I never noticed the case getting hot or the fans running, but it's nice to know they're there if needed. I suspect these will come into play on hot days when using it outdoors. Each section of output connections has it's own button to turn the section on. The AC section has two connectors on it, one of which you can plug a grounded plug into, although there's no connection for the ground prong, it's just an empty area that allows the groundpin to slide in so that three prong plugs can be used. Obviously this means that whatever equipment you plug in will work, but won't have ground protection. Above this section is an LED flashlight. It's quite bright and also has a mode that will flash S.O.S.. This would be very useful either in the back yard or camping at night. Moving to the left, the next bank of connectors is all about USB. There's five in all and they break down like this. 2 x USB-A ports (5V, 2.4A), 2 x USB-A ports QC 3.0 (36W if they stuck to the spec). Good for quick charging phones and tablets. And there's also a USB-C port. This is bonus port because it's a PD port and can charge things at up to 100W, like laptops, or it can be used to charge the power station. To do this you'll need a PD wall charger and fortunately I happen to have one, so I was able to try it out. This is a really nice feature, it lets you fast charge the power station quicker than the included wall charger. I tried both methods and with the wall charger it read about 60 watts, with my PD charger plugged into the USB-C port it read 91. When it arrived, it had 25% charge and it took roughly two hours to charge to full. Not bad at all. Moving left again we come to the DC out section. There isn't much explanation about this section and what the manual says is somewhat confusing. After doing some internet digging I was able to figure things out. You can run devices that you would normally plug into your car 12V power port (they used to call them cigarette lighters). This is labeled 12V 10A. OK, I get that. There's also a small connector next to it that reads 12V 8A. This is a DC6530 port. The purpose of this port is to power/charge things that use this style of connector, for instance, some laptop brands use this connector as the power input. Although these days, I tend to see more proprietary connectors on laptops. It's also used on other things, but you'll probably need to buy a cable to connect your device to the power station. There is a specific DC IN (13-30 V 80W MAX) port between the USB section and the DC OUT section. This is where the included AC adapter gets plugged in to charge the power station. If you want to charge the power station in your car, with your cars' 12V power port, you'll need to buy a cigarette to DC 5521 cable. A DC 5521 jack is what's on the power station and it's the jack the included AC adapter plugs into. 5521 translates to the actual size in mm of this connector (5.5 x 2.1). This jack can also be used with a solar charging panel, but again you need to connect it with a DC5521 cable. Another thing worth mentioning is the fact that you can dual charge this guy. That means you can use both the included AC adapter and the USB-C PD port to charge it from two sources at the same time. Plugging in both sources at once showed a power input of 151 watts. Cutting the charge time down to 1 ½ hours for a 0% to full charge. So all these labels and numbers are nice as a reference but the power station also has a really nice, easy to read LCD display. The one part of it that probably gets the most attention is the battery charge level. It's large and also shows a percentage readout right next to it. In the lower right hand side, it shows you the power coming in. This is helpful when charging the power station, and it's how I knew that the PD charging port was charging it at a higher power level. In the upper right hand side, it shows the power going out. This is how much power all the devices you've plugged into it are drawing. There's also small indicators that show you which banks of connectors you have turned on. The display is really clear and on top of that, it's back lit, so very easy to see in the dark as well. So after I fully charged it up I wanted to see how it worked. I hooked up a small (32”) TV to it, and a Blue-Ray player. I put on The Fellowship of the Ring and let it play. Well that only drew about 30 watts, so I also connected my Galaxy Book and two Samsung tablets to the USB section and turned on the flashlight for good measure. Well that only got me up to 76 watts. Safe to say I wasn't stressing it out at all. But for what I will be using it for, that's a fair representation. Mostly I'll use it in the back yard, or during power outages, or I'll put it in the car for road trips. So for me, this is the perfect size power station and it offers a collection of ports that most people would be hard pressed to overload. As another test I plugged in the power supply from one of my laptops and connected it. With the display on it got up to about 130 watts. So still not bad. This is a cool and compact portable power station that you could easily carry for a good long time and not get tired. It has a huge collection of ports to accommodate a wide range of devices. The display is easy to read and offers a lot of good information. I think if there was a way to make it better, it would be in the documentation. It would be to helpful to have more thorough examples of what you can hook up to what port. Clearly, I had questions about the DC output section and the manual was not much help. I think it would be beneficial to a lot of people if there were diagrams of how to use the ports. With a device like this that's able to supply a lot of power, you don't want to hook it up incorrectly. Granted, most of the connections are obvious, but a lot of people may not fully understand what the ports are actually capable of. This is especially true of the USB ports. Documentation aside, a great device. Well engineered and well laid out.

I have a smaller auxillary power station (physically and in terms of capacity) that I was using to charge my motorcycle's weak battery. That 135Wh unit would run out of juice within 3 hours from 100%. That's why I picked up one of these when it was on sale, hoping it could offer me charging time longer than that. So far it did not extend run time significantly, relative to my other power station even though this cost 3x as much (and I'm only comparing to the sale price I got for this). Also once, it mysteriously draied itself completely from full, I think maybe the build-in screen stayed on after I unplugged the charger. I am wondering if the unit I received was sitting in the warehouse so long before being sold, that it has lost its full potential. But I decided to keep it because I need more than one power station anyway.

It works great. I about it for my mother's oxygen machine and the power goes out. The only bad thing is it does not have three prong plug in her machine does. I can charge her portable machine on this though.

not bad, ended up returning since I found that the power capacity was minimal compared to other units in the same price range.

I absolutely love this item, because i can take it anywhere and charge it with almost any charger and it comes with its own fast charger as well and its a must have.
