This is an awesome little unit. Its small and compact and powers my Starlink Mini for roughly 11 hours. Just know that its only DC connection and has no wifi/bluetooth connection to the Ecoflow app. You can charge this device through the USB-C bidirectional input/output. Also has solar input for 110w max. Build quality is excellent and is geared for those who needs a travel sized DC-only portable battery station.

Style: TRAIL 300
I had always been a big supporter of Goal Zero and Jackery, but when I got a chance to buy and review EcoFlow's excellent Delta Pro not too long ago for our vacation home, I became a fan of the company's products. The Delta Pro's features genuinely wowed me at the time because neither Goal Zero nor Jackery had anything comparable. I had since bought and recommended the Delta 2 and River 3 series, though was not as impressed with them as they were comparable to the competition. I was curious to see how the Trail 300 would do. The Trail 300's 288Wh battery capacity - how long something can run for - means that it is lower capacity than their Delta and Delta Pro models, but comparable to the River product line. Such small sizes are generally used for day trips to recharge phones, drones, and laptops a few times and were not designed for home power backup or appliances, such as rice cookers or table saws. My use cases include powering my home internet modem and router (so I can continue working off my laptop during an outage) and to use my 12V mini rice cooker when camping. Then for the rest of the evening, it is used to charge my phone and illuminate the area with camp lights. Instead of using Nickel Manganese Cobalt (NMC), the Trail 300 uses Lithium Iron Phosphate (LiFePO4) like its more powerful Delta and Delta Pro siblings. There are significant differences between both Lithium-ion (Li-ion) battery chemistries that I will detail later. Some tips to keep in mind while reading my review: - How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts). - EcoFlow, Goal Zero, Bluetti, and Jackery power stations can be used while simultaneously charging themselves. CHARGER The biggest shortcoming I want to point out with the Trail 300 is the lack of a power adapter. You will have to supply your own. Every power station I had purchased in the past came with one -- perhaps the company is trying to save a little money due to rising inflation costs, or it is trying to reduce waste. Either way, you will need to get one. My recommendation is to buy a "140W USB-C Charger" from Anker or EcoFlow. Add a second 140W, and you can charge at 280W (140W x2) and be done 1.1 hours. If you get a less powerful one, that will still work -- it will just take a lot longer to recharge the battery. BATTERY TECHNOLOGY There has been a lot of debate on whether Nickel Manganese Cobalt (NMC) or Lithium Iron Phosphate (LiFePO4) is better. Both are Lithium-ion batteries. Goal Zero and Jackery used NMC for a long time and only recently switched to LiFePO4 (what EcoFlow and Bluetti had been using for some time). Why use LiFePO4 today? They hold some important advantages over NMC: - Safer, less volatile, and thus cheaper to manufacture - Charge cycle: 2000-5000 (10+ years) -- NMC: 20-25% capacity loss after every 500 cycle (6-10 years for up to 2000 cycles, after which capacity is vastly diminished) -- EcoFlow claims 3500 cycles before dropping to 80% of original capacity and 6500 to 50%. Each year, this number increases quite a bit as battery technology improves further - Usable in more extreme temperatures (-4F/-20C to 176F/80C). NMC: only 140F/60C max -- Check with manufacturer for your battery to be sure - Holds 350-day charge. NMC: 300 CAUTION: Lithium-ion batteries do NOT like to remain discharged at 0% for prolonged periods of time. If you let your battery stay at 0% for too long, you may not be able to charge it again without specialized equipment. CONTINUOUS VS PEAK OUTPUT It is important to understand the difference between Watts and Watt-Hours. How much power is used or produced is measured in Watts, and how much energy a battery can store is calculated in Watt-Hours. See the "Calculations" section below for more details. How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts). Trail 300 offers purely battery output (no AC output). It does so at up to 140W of DC per port for a total of 300W. So, peak and continuous output ratings that I usually cover in power station reviews become less important for the Trail 300. CALCULATIONS The below calculations are rough ESTIMATES as conditions, battery quality, and age can vary. [SORRY: I had to shorten my original review by a LOT (including many calculations) so it could fit here on Amazon.] Time to Charge This 288Wh Power Station - Calc: Hours to charge battery = Battery capacity (Wh) / Input Wattage -- As battery approaches 75% full, the input charge will increasingly be slowed down to prevent overcharging - AC Wall: 140W @ 2.1h [288 Wh / 140W] - AC Wall with 2x 140W chargers @ 1.1h [288 Wh / 280W] - 12V Car Charger -- 120W @ 2.4 hrs (at 10A, if car supports it) Charge Time with Solar - Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75]) -- In a perfect lab, solar panels charge at the listed wattage -- Expect to only receive 50-75% on a good, sunny day (ie. 75W – 113W for a 150W panel), depending on panel's age, component quality, and weather - 200W solar panel: as fast as 1.92 hours [288Wh / (200W x 0.75)] - Underproduction: If a panel is not making enough, adding extra ones can generate a higher, combined output - Overproduction: If the panels make more than the maximum the power station charge port can take, only the max will go through Watts Used/Produced by a Device - Calc: Watts used or produced by device = Voltage x Amperage - Vacuum with 120V @ 9.5A uses 1,140W - Solar panel with 12V @ 10A can produce up to 120W Ideal Battery Power Station Size - Calc: Battery capacity (Wh) = Watts used by device x Hours needed for / 0.85 -- 10-15% of power is lost during power conversion - 45W car fridge needed for 8 hours: Minimum 424Wh power station (45W x 8 / 0.85) FINAL THOUGHTS EcoFlow thoroughly impressed me with their Delta Pro power station and quickly added the company to my list of recommended battery providers. Their newest Trail 300, a LiFePO4 product, does not offer anything fancy except dual-port USB-C charging at 140W each, allowing the battery to be full in about 1 hour. The Trail 300 is light and compact, making it ideal for day trips and easy carry.

This is a fantastic compact portable power station that you can take it with you in the backpack. Before the T300 (Ecoflow Trail 300) was introduced, I always take the River 3 (R3) with me whenever I go on a camping or hiking trip. I thought I would settle down with the R3. At home, I daily use the R3 to power my laptop and phones. As soon as the T300 was introduced, I immediately fall in love with it due to its compactness and long use time before charging. The T300 is small and provide longer use time since it doesn’t have the inverter to convert to AC as that of the R3. The T300 is now accompanying me on my camping or hiking trip or at home in place of the R3. It is so compact that I can just out it in my backpack. I highly recommend the T300 to all hikers out there. I am taking the picture of the T309 next to the R3 to show how compact it is comparing to the R3.

Good idea, but they left off the 5521-barrel ports which are very useful for running many seemingly AC devices on DC to save the conversion loss. I currently run my modem on an ecoflow river-2 Max using the 5521-barrel port, this new device could not do that without some kind of adaptor.

Another well made Eco flow device that I thought I would not use very much. Boy, was I wrong! I have other larger products from EF and honestly did not think I would use such a small power storage unit. One of the first things that came up was a need to recharge my jump pack I keep in my truck. The trail 300 is compact enough that I can put it behind the seat and let it charge the jump pack without having to take it out of the truck! We also had a large community event at my church where I volunteered. The Trail 300 was available to charge my cell phone but still keep it secure in my vehicle. Those are just two examples of uses for this small device. Where might you need a very portable and easy to store power storage device? Give it a try, i know you will like it.
