What's in the box
Universally Compatible
EcoFlow solar panels use an all-inclusive solar connector, so you can even use them with your existing 48V power system. The 400W solar panel includes a 300mm charging cable that gives you plenty of space to mount multiple panels, maximizing solar input.
Off-grid & On-grid Solution
This high-wattage panel works for both on-grid and off-grid solar-powered setups, storing energy for outages, reducing power bills, or powering an off-grid home.
High Solar Energy Conversion
Made from highly efficient monocrystalline cells, the 400W rigid solar panel has an excellent efficiency rating of 23%, allowing you to charge faster than using similar-sized panels. Combine this panel as part of your existing PV system or Power Kits setup, and allow the integrated MPPT algorithm to optimize your solar input.
Waterproof & Durable
The 400W rigid solar panel is designed for the outdoors. With an IP68* waterproof rating and a robust anti-corrosive aluminum frame, the panel can withstand a wind speed of up to 130mph* and a significant snow load of up to 113lb* and continue to capture solar energy for years to come.
*Water and dust resistance were tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum water depth of 1 meter for up to 72 hours.) *Well-mounted solar panels can withstand a dynamic 2400pa wind pressure load (130mph wind speed) and a static 5400pa snow load (113lb per sq foot of snow).
Easy Installation
Thanks to our plug & play solar systems, you no longer need to rely on electricians, tradesmen or other installers.
Flexible Mounting Options
Thanks to its integrated mounting hardware, the EcoFlow 400W Solar Panel can be easily installed in a variety of locations, including balconies, flat roofs, and garden spaces.

Stainless steel material looks sturdy and easy to clean
Style: No Stand, Color: Black
It has a compact and elegant design, in addition to feeling comfortable in the hand. In a few seconds it achieves a creamy and soft foam, perfect for coffee, cappuccinos, matcha or hot chocolate.

Fantastic foam!
Color: Black, Color: Black
Bought this so I can cut down on my trips to Starbucks and recreate those drinks "to go" at home.
It works for making any kind of foam...most recently been whipping up 1/8c half n half with it and added syrups for my iced coffees I take to work.
Soooooo worth the money. Starbucks quality foam (if you're not a coffee snob) at home. I now enjoy having iced coffees with salted caramel or chocolate creme cold foam that costs less than $2 to make at home versus $15 at the drive-thru.
Time & money saved!

High speed

Nice high speed, froths a lovely froth. I like that I won’t be changing batteries every month.
