Fantastic Fast Delivery of a Quality Product
This EcoFlow 2Max Extra Battery was delivered today and I am very pleased to say it so far functions very good and nothing was broken or damaged during the shipping and delivery process as before in a previous same purchase. I can confirm that the operation and functionality is exactly as described in the advertisement for this product and additional 2048 Watts to my solar generator system will definitely cover my electricity needs during this upcoming summer months and fire season when the main power supply grid is shutdown for public safety. I would recommend these devices be purchased for your homes in case of any future power outages because they are very efficient and and very easy to use and will save you money and discomfort during the upcoming months. Long story short, the EcoFlow company works with customers to help purchase their products by offering different types of payment plans that are compatible with many budgets so anyone can afford to pay for a important product that will help them during power outages that occur very frequently nowadays. Thank you (I’m pretty sure I will purchase one more extra battery so I can run my air conditioner when the heat is causing the power grid to be shut down and instead I will be enjoying my regular life without disruption and sweating in the heat waiting for the power company to turn back on the grid power supply to every house )

At the sale price I got, a very good deal indeed.
I had my eye on this for some time and when it became $200 it's than the lowest sales price I had seen to date, I pounced. I like the Ecoflow system 48v LFP batteries so the wires so not over heat with no worries of exposed terminals and using the charger built into my DELTA 3 Plus. Yes it works perfectly with the D3 Plus, giving me an extra 2kwh rather than the 1kwh that comes with the D3 extra battery without the adapter or weight of the Pro's 4kwh option.

Ecoflow is the way to go!
Freak storms and power outages seem to be the norm these days. A year ago, I purchased the Delta 2 Max and added a battery to provide emergency power in the event of a blackout. I just added a second battery to ensure uninterrupted power. Ecoflow products are user friendly and very reliable. I power these with 2 400 watt solar panels and these have maintained a steady supply of power. I cannot say enough about the peace of mind that the Ecoflow system has brought to my household.

Dependable extra power
Arrived in great shape, and plugged into my Delta to max right away to equalize the charge and both batteries are now up to 100% well done EcoFlow. I look forward to using this in my RV camper
