Ecoflow DELTA 1300 Lithium-ion Power Station + 160W Solar Panel Expired

Your question leaves out so many variables. Are you talking about in your RV or camping? Then yes, this is a good choice.

For your home?
If you want to power some small things for a few hours on the first night of an outage, yes.
If you're in a multi day outage and want to use things in your home, no.

You can power a normal size fridge for about 7 hours, but if you mix in using a microwave or coffee maker, using lights, having a modem and router running with a pc, you're looking at like 1.5-2 hours, maybe slightly longer if the sun is shining. If you're going to run a typical space heater, MAYBE an hour of juice. The problem is if you are using this during the day, it simply won't recharge fully and when the sun goes down you are not going to make it with lights/basic electronics for more than a little bit.

The efficiency rating of this setup is absolutely horrible, like 55% if I remember right. so for every 1000w you put into the battery, you actually are losing 450W because of the very poor battery bank. Lithium ion batteries are normally in the mid 80% efficiency level, but because of how wasteful the charging unit is on this unit, you're going to lose a bunch of that juice. Most quality pieces are in the 73%-89% range. Look up Solar RTE, or round trip efficiency .

As stated above, if this is used every once in a while as a battery bank that you are charging from the sun, it's not that bad of a deal, but if you think this will get you far during a power outage, especially if you are in a cold climate, you really need to buy something quality.
