For 2 months in the tardy summertime , I had the opportunity to test the EcoFlow Delta Pro 3 portable office station during a unretentive storm - related ability outage at my sign of the zodiac , on a sunny weekend camping trip with my small travel trailer , and for a few extra controlled tests . Since the kit I tested came with a400 - watt solar panel , I was capable to try several charging combinations and happen out what happens during coinciding solar charging while powering my camper . Testing this product gave me a flock to consider , on its own and compared to other portable power stations and inverter generator that I ’ve tested . learn on to learn more .
Jam-Packed With Premium Features
TheEcoFlow Delta Pro 3was designed to power essential base appliances through a tycoon outage or to conveniently deliver electricity on the go . A 4,000 - kilowatt - hour lithium branding iron ( Li - Fe ) battery bank is at the core of the exponent place . The sealed battery bank is IP65 - rated dustproof and waterproof , supporting indoor and sheltered outside operation . It offers years of honest service , with a working lifespan of 4,000 armorial bearing cycles .
charge options are plenteous . The EcoFlow Delta Pro 3 offers seven singular and 18 compounding charge method . It supports 120 - volt and 240 - volt AC charging , high- and low - voltage solar charging , car charging , and compounding charging through AC and solar ports at the same prison term . Charging time variegate : 50 minutes to 80 percent and 2 hours to full thrill using an AC wall outlet ; 12 to 24 hr using a exclusive 400 - watt solar gore ( the social unit substantiate up to three solar panels for charging in as trivial as 4 to 8 hours ) ; or about a twenty-four hour period and a half through the railway car charging interface . It also allows for solar charging while outputting ability .
mightiness output is where this unit unfeignedly scramble . It is capable of run multiple twist at the same time , including high - power - draw household appliances , with up to 4,000 running Watt and 8,000 surge James Watt . This is one of the few portable exponent stations to include three high - outturn outlets : a 30 - amp RV ( TT30R ) outlet , a 120/240 - V carry-over switch ( NEMA L30 - 14R ) exit , and a 240 - volt appliance ( NEMA 5 - 20R ) outlet .

As you might bear from a top - of - the - logical argument power place , the EcoFlow Delta Pro 3 offers undischarged monitoring and ascendence choice . It features independent onboard controls to activate the 120 - volt , 240 - volt , and DC electrical outlet clusters . The digital video display show the input signal electrical power , output electrical power , charge status , and remaining runtime ground on current usage . It is also Bluetooth and Wi - Fi enable for outback monitoring and control through the EcoFlow mobile app .
As a whole - dwelling house backup man scheme , EcoFlow Delta Pro 3 is expandable to 48 kWh if you max out on battery add - ons and parallel connections . It also integrates with the much broad EcoFlow ecosystem . In this form , it can remain plugged in without the hazard of rob or premature battery failure , thanks to a overbold charge direction system . When backing up sensible electronics , the 10 - millisecond Uninterruptible Power Supply ( UPS ) ensures that nothing suffers from an electrical disturbance .
Built to Transport, but Loading Can Be a Challenge
As a portable great power post , theEcoFlow Delta Pro 3is larger , arduous , and supply much more ability than most of its competitors . I wish that it was readily fit to power my RV without an arranger , so I give it a try as before long as potential . The telescope hold and 4 - inch wheel make it fairly comfortable to move across strong floor and paving , but I used a cart for any extensive movement over grass , gravel , or other scratchy flat coat .
With the exponent station being about the same size of it as a magnanimous cooler , I had to plan the wadding arrangement as I organise for my encampment trip . If I were railcar tenting in a tent , this social unit might be too large , but it was just right for my locomotion trailer . For comparability , I normally use a 4,500 - wattinverter generatorto start the camper , and this power station was similar in sizing and exercising weight .
Loading it into the truck contract some effort , even for two hoi polloi , but the molded handgrip on either end foreclose some hand and back strain . Instead of a rubberized overmold or other built - in cushioning scheme , this model has textured grip protector strips to wrap the handles . The fit is cozy to resist slipping and give the handles just enough padding .

begin with the fully charged power station , I calculate that I could power the motor home from Friday night through Sunday sunrise , but I also wanted to try out with the solar board . It needed extra distance — the dimensions are 42 inches long by 26 inches broad by 2.5 inches magniloquent in the memory board cup of tea — so I secured it inside the camper . If I were boondocking for a calendar week , I would need to have two extra solar control board to hedge against less - than - ideal cheerfulness .
Lots of Power for a Little While…or a Little Power for a Long Time
The manufacturer ’s website claims that the EcoFlow Delta Pro 3 can run a home icebox for 3 day . I tested it in camp on a warm , clear day with temperature in the upper 80 degrees Fahrenheit . I plug away the camper into the power station and turn on theair conditionerand icebox ( which was still warm in spite of appearance because I did not precool it with gridiron big businessman at home ) .
I noted the power draw of the electric refrigerator ( 170 to 180 Isaac Watts ) , air conditioner ( 755 to 780 watts ) , and both combined ( 890 and 910 watt ) . After the first hour of both gadget running ( in active cooling mode essentially the whole time ) , the exponent place charge was depleted by 5 percent . When I added the solar panel ( face in the south , fish about 45 degree ) , the solar input reading material ranged between 320 and 335 Watt . After a 2d time of day of course both appliances — while solar charging at the same time — the charge only depleted an extra 2 per centum .
After I use up those run reading material , I put away the solar panel and turn off the strain conditioner until later that nighttime when I needed it . With my normal tenting usage patterns from Friday night through Sunday morn , which include keeping the electric refrigerator plug away in , start the air conditioner only while I slumber , and occasionally using the microwave for a minute or so at a time , theEcoFlow Delta Pro 3still had an 18 percentage charge when I kick the bucket home .

At household , I recharge the power station and set it up as a charging fundament for my home ’s four laptop computers , four headphone , and three tablets . I was surprised to see how slowly the commission depleted . After 2 week , I ended the experimentation , and the mogul station still had a 51 percent heraldic bearing .
