Review: Excellent power station for camping - easily powers NHS issued CPAP for two nights before recharging - Review from an off-grid user based in the UK - power your CPAP using the sun! My primary use for this Portable Power Station was to power an NHS provided ResMed Air10 Autosense CPAP machine. After extensive research I was still unsure as to which power station to go for until I contacted EcoRiver for their recommendation on which one would meet my needs. They recommended this one - and being much more powerful and more expensive than the original one I was looking at I was initially a bit skeptical. However this machine is the minimum you need to power your ResMed Air Sense 10 Autoset on AC power (it is more efficient to power it using the 12V DC to DC converter, available from ResMed, but as far as I know this option means the humidifier function on the CPAP machine does not work as it needs more than 12V). Using this machine I could power my CPAP machine on AC power, just like at home, for two nights without recharging, using the humidifier function. However I used EcoRiver's excellent 400W solar panel (which I will review separately) to recharge it every day, meaning I had tons of extra power left over. This machine can easily power a toaster or microwave and can even power a powerful mains powered GHD hairdryer for a short time. DOMESTIC KETTLES NO - TRAVEL KETTLES AND LOTS OF OTHER THINGS YES! It would NOT be able to power a domestic voltage AC kettle as these use typically 3000W for a short time - when off grid in my view you're better off using gas to boil water rather than a domestic kettle - though it will easily power travel kettles, full domestic power AC toasters, lower wattage travel toasters, and all manner of other gadgets. It goes without saying that if you're planning to use lots of high wattage tools for a long time you will need an even bigger battery but for phones, tablets and laptops this machine more than has you covered. At times during a recent camping trip it was fast-charging four phones simultaneously. SILENT CHARGING FROM THE SUN! Before I bought this device we had to rely on a petrol powered 1800W generator to recharge things and use a TV in the caravan, which is loud enough to be pretty antisocial not to mention the fumes. Using this battery paired with a 400W EcoRiver solar panel provided free, silent power. Even on heavily overcast days with light rain, the panel was still providing 40w input power, which would recharge the battery over 6-8 hours from 50% full. In direct bright sunshine, the panel once recharged the battery from flat in two hours, which is an amazing amount of power. MAINS AC RECHARGING IN BAD WEATHER/WHEN MAINS POWER IS AVAILABLE This battery can recharge off a normal mains AC outlet, drawing 1200w, in about 50 minutes, using the provided kettle-style lead. Fairly loud fans kick in to cool it during this which is reassuring. This was a great feature off-grid as during one period of intensely heavy rain and dense overcast lasting two days I ran the battery flat and was able to recharge it using the AC outlet of a petrol generator in less than an hour. This is an amazing piece of kit and the accompanying app for iPhone is very clear. It was great to be able to check the solar charging was working well and how much power was flowing in and being used simultaneously. It is worth every penny. Buy it.
Review: Excellent Portable Power Generator - This is an amazing piece of kit that requires a detailed review ! Having recently heavily researched Solar power generation due to the massive increase in energy prices i decided to spend some of my hard earned cash in this technology to see how well it performed. I initially purchased a 537wh Bluetti EB55 along with a 200w solar panel. Whilst this performed well i was disappointed at how quickly the battery drained with medium draw appliances, and the fact the Bluetii display was information poor, ie no exact battery percentage or estimated time of power draw left. I also only wanted a LiFePO4 battery due to the serviceable life of these batteries (3000+ Charges/Cycles) compared with standard lithium ion batteries which are only around 800 cycles. The market was very limited for these type of devices, hence why i choose the mid-range bluetti. I did rush into this purchase and kind of regret now understanding watt hours and power draw. After a few days of use and a lot more research it did get me hooked on the future of this technology and the fact i could harvest free energy from the sun. As a direct result of my first experiment i did some more research and found that ECOFLOW were releasing a LiFePO4 generator - so i decided to invest some serious cash in the Ecoflow Delta 2 and pre-ordered. The ECOFLOW Delta 2 is a lot bigger than my Bluetti, however it does have around twice the battery capacity and additional power outlets. When it arrived my first impressions was that this was a very well built premium bit of kit. Turning on the device i noticed that it was around 38% charged so i immediately connected it to my 200w solar panel. The day was fairly cloudy was intermittent brief sun, after a few hours i managed to get the battery up to the mid 50's. I wanted to test this device with 100% storage power so decided to connect it to my house mains to charge the remainder of the battery. Although i never intend to charge this via mains electricity i wanted to test the quick charging functionality for emergencies. The first thing that i liked about this over the Bluetti was that there was no external charging brick (that's a huge drawback for me when i do a direct comparison) the Delta 2 just has a standard kettle lead which you plug directly into the unit and the mains. Within a couple of seconds of doing this the fans for the unit kicked in - wow they are loud and powerful. I have uploaded a video of this so you can see how loud this thing is when AC charging. The unit drew between 1kw and 1.2kw of electricity from the grid, and wow this thing can charge fast! 0-80% in 50 mins! As i already had over 50% charge it didn't take long to reach 100% capacity - the unit lowers the charging rate +80%, and the fans slow down somewhat - but you can definitely still hear them. When charging via Solar the fans were not nearly as loud. You have an option in the app (more about that later) which allows you to limit the AC Charging rate, which in turn should lower the fans. Included with the device is an MPPT to 12v car charger so you can also charge this device from your vehicle. Now for the power test! I wanted to see if this unit could power my UST Projector, and if so how long for. Plugging in my projector the display showed a power draw of 312w, this meant i would be lucky to get 3hrs from the unit which wasn't ideal. I therefore lowered the brightness of my projector down to 50% and this increased the draw time to 5.5hrs. I was super happy with that! We used the unit all evening to watch TV on our projector and the battery was down to 7% - i was super impressed. Over the next few days i did a ton of more tests on this device and all impressed me. I loved the fact that the display showed me the exact battery percentage, the power draw from the devices and the remaining time. Using the USB sockets on the front of the device i was able to charge all of our smaller gadgets like phones/iPad's etc. I even asked my partner to power their two work laptops from the Delta 2, this also worked fantastically. With lower powered devices you could get several days use out of the Delta 2. A rough calculation of the usage time compared to the 1024kwh battery worked out to around 84% during my real word tests - this is relatively standard across the battery generator range when allowing for Inverter draw and displays/wifi etc. The Delta 2 also has pass through charging which allows you to solar charge and draw power at the same time. Over the weekend we had some fantastic sun, and all of my Delta 2 energy was drawn from my solar panels - i have now upgraded to two panels to increase the charging times. The Delta 2 at it's peak was drawing +300w from my panels in bright sunshine. The charging time for this was showing around 3.5hrs. I am confident in the summer months i could easily draw 1kw and fill the batteries in just one day of sun. The device has 4 x 3 pin UK AC Sockets on the rear, along with the MC4 solar input connection and the AC Kettle plug for AC charging. Here you will also find a reset button should you ever need to use it. Also on the rear is a 12v cigarette input and 2 x DC5521 barrel inputs. On the front of the device is a lovely crystal clear LCD display which shows you a wealth of information such as time to charge remaining, time of discharge remaining, watts in and watts out and a very clear battery percentage. You also have 2 standard USB a sockets 5v 2.4a 12W max, 2 USB A Fast Charging Sockets 5V, 2.4A / 9V, 2A / 12V, 1.5A, 18W Max, and two USB C sockets 5/9/12/15/20V, 5A, 100W Max which support super fast charging. The USB C sockets are powerful enough to use and charge my laptops at the same time. Each group of inputs has an individual on/off button to switch on that part of the inverter. Individual control is better as this will save unnecessary battery drain. Another huge benefit of owning this device is that it is also Bluetooth and Wi-Fi compatible. You need to download the free ECOFLOW app and this allows you to see input/output rates on your phone even when you are away from home/the device - it's basic but works well. I loved the fact i could be at work and check the solar wattage going into the device! It was kind of addicted. The app can sometimes mess up and not update correctly, but i am hoping this can be fixed in a software/firmware update - which incidentally can be sent to the DELTA 2 via your phone/tablet! The DELTA 2 can handle devices up to 1800w with a surge boost of up to 2400w. This enables this device to power pretty much any standard electrical appliance plugged into it and it will work, albeit perhaps at a lower wattage if the appliance likes this, ie heat guns etc. The device also has a built in UPS so that if your mains powers goes out then the device will switch over to carry on powering your devices - it does have a few milliseconds' delay (unlike my purpose UPS device) but for most electronic equipment this should be fine. It also output a true sinewave, so sensitive appliances like computers etc would be fine with the Delta 2's power supply. Solar input maxes out at 500w. You need to be super careful if you are connecting this to multiple solar panels though so that you do not go over the voltage which maxes out at 60V 15A. Before you invest in solar panels always check the Open Circuit Voltage (OSV) of the panel to ensure it is within the range of 11-60v, one panel will be fine but adding multiple panels can take you close to this range if not over - you should always allow a 20% threshold too for cold sunny days. Working out solar compatibility is a bit of a minefield, but after weeks of research i believe i now understand the basics. To help you if you connect two or more solar panels in parallel with a Y adapter then the voltage of the panels remains the same but the amps are added together, if however you connect in series (positive to negative leaving only two MC4's) then you need to add the voltage of all your panels together and the amps/current remains the same. Thus, be super careful not to exceed the specs of the Delta 2 or you could seriously damage it. So in summary would i recommend this device - without hesitation YES! This technology is still super expensive, however it is an absolutely amazing product i really wish i had found this product before i purchased my Bluetti - it excels the Bluetii in every single way! To generate free electricity from the sun is fantastic, but to store it to use later is beyond amazing. This little guy does it all and does it very well... excellent storage capacity at just over 1kw of electricity (Around 28p at time of writing this review) truly portable - weights around 12kg, but has great handles to distribute the weight evenly, you can even add the battery expansion pack to take this up to over 3KW! Firmware updates are provided via the app to the device so it stays current, fantastic detailed display which is easy to read even in sunlight, great phone app, fantastic selection of power ports, fast solar charging, super fast AC charging, expandable up to 3kw with the additional battery pack, 8.2yrs of daily charging before battery depletes to 80% capacity & to top that ECOFLOW offer a full 5yr guarantee. I honestly can not recommend this product enough if you want to invest in a small solar energy setup - purchase cost to payback would work out at around 10yrs (excluding solar panels and wiring) with current energy prices at 0.28p per KWh, however this isn't all about money, this device is about emergency power, portable power (camping etc) being more green and protecting the environment. I genuinely love this product and wish i had purchased this before i wasted money on my Bluetti. I intend to save up to buy the add on battery pack... but rather disappointingly that may be a while yet! I hope that you found my review helpful.

It also output a true sinewave, so sensitive appliances like computers etc would be fine with the Delta 2's power supply. Solar input maxes out at 500w. You need to be super careful if you are connecting this to multiple solar panels though so that you do not go over the voltage which maxes out at 60V 15A. Before you invest in solar panels always check the Open Circuit Voltage (OSV) of the panel to ensure it is within the range of 11-60v, one panel will be fine but adding multiple panels can take you close to this range if not over - you should always allow a 20% threshold too for cold sunny days. Working out solar compatibility is a bit of a minefield, but after weeks of research i believe i now understand the basics. To help you if you connect two or more solar panels in parallel with a Y adapter then the voltage of the panels remains the same but the amps are added together, if however you connect in series (positive to negative leaving only two MC4's) then you need to add the voltage of all your panels together and the amps/current remains the same. Thus, be super careful not to exceed the specs of the Delta 2 or you could seriously damage it. So in summary would i recommend this device - without hesitation YES! This technology is still super expensive, however it is an absolutely amazing product i really wish i had found this product before i purchased my Bluetti - it excels the Bluetii in every single way! To generate free electricity from the sun is fantastic, but to store it to use later is beyond amazing. This little guy does it all and does it very well... excellent storage capacity at just over 1kw of electricity (Around 28p at time of writing this review) truly portable - weights around 12kg, but has great handles to distribute the weight evenly, you can even add the battery expansion pack to take this up to over 3KW! Firmware updates are provided via the app to the device so it stays current, fantastic detailed display which is easy to read even in sunlight, great phone app, fantastic selection of power ports, fast solar charging, super fast AC charging, expandable up to 3kw with the additional battery pack, 8.2yrs of daily charging before battery depletes to 80% capacity & to top that ECOFLOW offer a full 5yr guarantee. I honestly can not recommend this product enough if you want to invest in a small solar energy setup - purchase cost to payback would work out at around 10yrs (excluding solar panels and wiring) with current energy prices at 0.28p per KWh, however this isn't all about money, this device is about emergency power, portable power (camping etc) being more green and protecting the environment. I genuinely love this product and wish i had purchased this before i wasted money on my Bluetti. I intend to save up to buy the add on battery pack... but rather disappointingly that may be a while yet! I hope that you found my review helpful.

### ⭐⭐⭐⭐⭐ Excellent addition for anyone wanting to avoid campsites

The Delta 2 is cheaper, lighter and both more powerful and easier charged than its predecessor. We have one in our Motorhome and it has made off grid so much easier and pleasant. It will power the Moho as a single entity replacing Electrical Hook Up (EHU) if you want or you can power individual items including microwaves and coffee machines. Recharging it is easy, we have a 220 Ecoflow solar panel that can be put out for charging swiftly in sunlight, or charge via your normal 12v cigarette lighter socket when on the move. If on an EHU it’s very quick to recharge and you can set the input level so as not to trip the site electrics if need be. We have just used it for a month away in Spain and Portugal and spent half our nights off grid in beautiful locations with the capacity to live as if on a site with full EHU. It can also power the fridge but probably for 6 hours max whilst receiving a good solar recharge from the panel at the same time. Two coffees on a Nespresso machine is about 7% of capacity, 25 minutes solar or driving and it’s back to full capacity. Great bit of kit and portable to another Moho or easily lent to a friend as oppose to fixed lithium battery systems.
