Compared to traditional fuel generators, it can save 40% of fuel when fully charging EcoFlow DELTA Pro 3.

Power Backup Made Smart and Simple

With four intelligent self-starting backup modes (when paired with EcoFlow DELTA Pro 3), power backup has never been easier.

Customizable start/stop

At night, once the power consumption reaches a certain level, the smart generator will automatically start to replenish power, eliminating the need to get up in the middle of the night to reset it.

Night-care mode

Monitor the remaining power of the EcoFlow DELTA Pro 3 energy storage in real-time, predict future power consumption and measure the power generation from PV, and auto-recharge it in time to ensure a peaceful night's sleep and rest for your family and neighbors, avoiding noise during charging at night or during peak power consumption periods.

PV-priority mode

Recharge the EcoFlow DELTA Pro 3 with PV panels, automatically prioritizing PV charging for savings and environmental benefits while minimizing noise from continuous generator operation. Need more power quickly as an outage approaches? One tap in the EcoFlow app switches back to PV and Smart Generator charging combo for swift reinforcement.

Smart reverse charging

It provides a reverse power supply to the generator battery through EcoFlow DELTA Pro 3 to wake up the generator and start charging it at the same time. Also, to prevent the Smart Generator battery failure caused by long-term storage or extremely low temperatures, it protects household electricity during severe weather scenarios.

Dual Fuel for Double Peace of Mind

Rest easy knowing that LPG and gasoline are readily accessible, ensuring you can quickly obtain fuel for backup power and alleviating concerns about fuel shortages during emergencies.

Gasoline Power

The smart engine produces 8kWh in single gasoline tank, you could power your home appliances for 8-hours at 25% load.

A Staple in my Skincare Routine
Scent: Unscented, Size: 25 Count (Pack of 3), Scent: Unscented, Size: 25 Count (Pack of 3)
I've been a huge fan of micellar products ever since they came onto the US market and these Simple Micellar Makeup Remover Wipes are no exception! Simple products are known to be gentle and easy on the skin. These wipes stay true to the brand and feel great on the skin! I have combination, sensitive skin and over the years, I've become quite diligent in taking my makeup off before bed. Although I have tried countless popular brands in the past, these Simple Micellar Makeup Remover Wipes are the ones I keep coming back to time and time again. These wipes are my first step of action in removing my makeup and they do a pretty great job of taking off everything. I usually hold the wipe over my eye area for a few seconds to allow the makeup to break down and come off onto the wipe--I've found that this does a good job of removing my mascara, eye liner and shadow. These wipes do not cause any irritation to the eye area and are great to use on the sensitive skin of the face. To take off stubborn or waterproof makeup, I just apply a liquid eye makeup remover directly onto the wipe and have found this to be the easiest and least wasteful method. I usually wash my face afterwards with a gentle cleanser and continue on with my skincare routine. However, on the nights I'm really tired, I rely on these wipes to remove all of my makeup. These wipes do not leave any type of chemical residue behind and make my face feel fresh and clean. The Simple Micellar Makeup Remover Wipes are a staple in my skincare routine. I keep one pack in my bedside table for easy access on the nights I'm too lazy to wash my face, one in my vanity, and another in my gym bag--I clearly like to stock up! I highly recommend these wipes; they are a must try for everyone!

Great, but different.
Scent: Unscented, Size: 25 Count (Pack of 4)
I've been buying these for a while now. I love them because I have really sensitive skin and these clean my face without leaving a greasy film, or irritating my skin like other face wipes do. Mind you, the only makeup I wear is mascara though, so it's really only cleaning off oil and dirt. They don't dry out my face either. The only problem I have with these, is that, the last batch I ordered (while in the same packaging, and having no difference in looks or labels) is different than what I had previously been receiving from the same company. They smell different (actually better in my opinion) and they do NOT remove my mascara as well anymore. I still love them, because it does help keep my face from being excessively oily and keeps it clean other than removing my mascara. Though I am disappointed that I now have to get a different brand wipe just for removing my mascara now.

Best of the facial wipes
Scent: Unscented, Size: 25 Count (Pack of 3)
I have used a lot of facial wipes. But, because of environmental reasons I am trying to cut back on the excess use of wipes which will go into a landfill. However, there are times when I am just too tired or too lazy to do a whole cleansing routine at night and I will reach for a wipe. These do a good job of taking off even waterproof makeup and yet still being gentle on the skin. I find I have no sensitivity to them(and I am sensitive to many, many things). I bought them specifically this time for my trip to Thailand because I knew it would be hot and humid and that I probably would need to cleanse my face a couple of times during the day from sweat and grime. They worked and I found them refreshing. I think I will always keep them on hand for the times I need them — this is by far my favorite brand.
