Transcend Portable Solar Power Battery Charger

Traveled first year with our RV all the way from Virginia to Colorado…. Boon dock a couple of places and it was darn hot!! No power. We had our portable fan as to minimize RV battery but just could not cool it enough. I have added and upgraded our RV battery since last year. In addition I purchased the ecoflow pro, ecoflow pro extra battery, ecoflow portable generator, and also the ecoflow 400W solar panel. I have tested it out and so far it works pretty darn good. Granted it will provide only 6 hours to power essentials and running one of 2 15k BTU AC. Of course I had to add softstart to the RV AC (very easy install). I plan on buying additional extra battery from ecoflow and of course double capacity to the RV batteries as well. Anyway for a beginner RV’er this solved my problems for cooling without excessive manipulation to the RV power system. I just used the 30A converter to 50 A directly to RV power input…and will power on for at least 6 hrs without the 400w solar and portable generator (haven’t tested generator yet) connected. We will see how it goes this year but so far I am very happy with our ecoflow system. Side note I build solar panel holder with pvc wood as it is light, flexible, and easily transported in RV…set it up so it will take less than 5 min to set up.

The Dou charger not only allows the charge of 2 batteries but it can use different power supplies. I am able to charge 2 batteries at a times using a solar battery pack such as the DigiPower Solar Portable Dual USB 15,000mAh Battery RF-PBSLR15 (bhphotovideo.com). It can also be plugged into any USB charging port.

Excellent compact solar charger. Very light weight and portable. When paired with the 220 bifacial panel it's a pretty tough to beat for it's size. Excellent camping buddy.

I have several Power Stations, even some I built myself, but nothing come close to this. EcoFlow has really outdone themselves. The feature rich unit is strong, powerful, yet extremely lightweight and even expandable. I bought the Extra Battery as well. The ease of use and portability make this my favorite hands down. This unit packs a ton of power and features into an really small package. The WiFi feature allows me to keep an eye on it from anywhere, Just like my off grid solar for my home. I can easily look to see the SOC, loads, solar input and many settings. The Delta 2 along with the Extra Battery are the best companions for off grid RV’ing, parties, worksites, power outages, emergencies and so much more. I reach for the Delta 2 and its extra battery when I need power to go from now on. I have portable solar panels to keep it topped off. This is by far my favorite power station, and I highly recommend it to anyone looking for one. It gets 5 stars from me!

I’ve had a few different cameras, and tried this one mostly for the solar power and battery life. It was a winner! Battery life is great and the photos are clear with good range. I switched all mine to this one!

This ecoflow delta I got , is portable and very convenient to use. Also do not forgot to buy solar panel which also help to gain extra free power from the sun. Any parts you need afterward you can order from company website very quickly. They are fast and efficient. I strongly recommend everyone looking into this , also because This is new generation battery you can charge faster and more time than old delta model. Again I will recommend this to my relative if they look for back up power generation device and also solar capacity.

I finally had a day with some sun to get out and really test my EcoFlow Next Gen 160W panel. I was pleasantly surprised with the performance and ease of setup. At 11AM EDT (early October) I was able to peak at 130 watts input into my power station. I averaged 125-128 watts until my power station battery approached full when the MPPT slowed down the charging until my station was topped off. This is about 80% efficiency, which is about exactly what one should expect in real-world conditions and good sun. I specifically bought an EcoFlow portable panel, because I'd seen many positive reviews, and they're IP68 rated (waterproof and dust proof). The integrated sun dial was a definite plus as it helped me get the panel set at the optimum orientation to maximize solar input. The storage case is really nice too! I kept the foam padding included from shipping to pad the panel as it folds for storage. I will definitely buy another one of these panels, or a NextGen 220W panel as I expand my portable solar setup.

I researched Solar portable power for about six months NOTHING comes close to the EcoFlow Delta Pro.

I am new to the whole portable power station world, but this is an excellent first time purchase! I primarily purchased this for the back of my truck camper build, but I find myself using it in every day activities. I leave my laptop and switch plugged in to it during the day, and at night I charge my phone with it. I enjoy the 220w solar panel combo for the river 2 pro. An excellent pair! I have enjoyed powering every day object's with green solar power and am definitely considering more products from eco flow. Overall very well built and I am very pleased with my purchase.
