It seems like a very well made piece of equipment. The first one I got did not work properly, and it wasn't charging rat, and I had to return it. They stood behind everything, but there's return. Policy is very time consuming. After submitting everything anytime I would respond my response would put the whole process at the bottom of the queue to start over again. With that situation, the whole process took three or four weeks. Part of that time frame was because the batteries have to go on ground. In not air, so that slows it down quite a bit in transport. Very satisfied now, even have 2 extra battery packs to tie onto it. Everything is good.Just don't expect a rapid response to a return & replacement.

I am a long time user of Jackery batteries. I was very excited when the Explorer 2000 plus was released. This is the very 1st expendable battery system that Jackery has released. It allows up to 12kwh capacity on a 3000w 120v output, or 24kwh on a 6000w 240v output. Perfect upgrade for my home backup. Jackery Explorer 2000 plus uses the new LiFePO4 battery cells. The LiFePO4 cells are much safer comparing to the Li-Ion cells. It can operate between -4F to 140F temperature, and much better performance in a cold environment than the Li-Ion cells. The LFP( LiFePO4) cells is rated 4000 cycles to 70%+, and the Li-ion cells is rated 1000 cycles to 80%. It can last about 4 times longer than the Li-ion battery cells, can easily last 10 years on a daily use. That’s great for a daily home power backup solution!! Since the density of the LPF battery is different from the Li-Ion, it makes it a little heavier than the Li-ion batteries. The 2000 plus weighs about 61.5lb, and the 2000 pro weighs about 43lb. Almost 20lb heavier than the Li-ion battery. Portability wise it might not be the best option, but for a long lasting purpose this will be great! That’s why the 2000 plus has built in wheels, and handle to make it easier when transporting the battery to different locations. Then 2000 plus inverter can output 3000w max, and 6000w surge peak, where as the 2000 pro can only output 2200 w max, and 4400w surge peak. That means, I am able to power more devices around the house with this battery. I was even able to charge my Tesla with this battery as well. Even tho it’s only one level 1 charging, with 120v 12 amp, I can get about 10 miles of driving range from the 3kwh amount of power. Not bad for emergency needs. The Jackery control app is very useful. I can pretty much control everything via the app. I can adjust battery charging speed, output on/off, monitor output voltage, % of power left, temperature and more. The app can connect to the battery via bluetooth, or wifi. When connected via wifi, I can access my battery from anywhere, as long as I have internet access. This makes it so much easier to make changes when I am not home. I don’t see any web version of the app. I am hoping that Jackery will provide some type of web access as well, that will be even more useful as a backup, if something happens to the smartphone. I am super excited to see that the expendable setup allows up to 5 additional expansion batteries to connect to one 2000 plus base unit. Which max at 12kwh capacity. That can easily run the whole house for 24 hours or more. This makes the system really flexible, depending on my needs I can customize the capacity that fits my lifestyle. With the 30 amp outlet, I am going to connect to my transfer switch at home, so I can use this to backup the whole house for emergency purposes. Right now I have 4kwh, I am planning to upgrade to 6kwh in the next few months. I am super excited, with the possibility I have with this new expendable design.

Great solar backup battery system. I purchased an additional 2k battery ... so now I have 6k watts, for power outages.

I now own two of these, bought at different times, so that should give you some idea what I think of them. They are good, but could be improved. The main issues I have are: 1. Being able to turn on/off the battery saving feature, which limits charge and discharge, can only be done if the device is below the high end charge limit. That is rather frustrating, but not a huge deal. 2. If you have one or more of the expansion packs, how it uses power from those packs seems to be random. That matters to me because the second base unit I have is for charging these packs. I would like the base station to use the packs first, or be able to tell it to use them all simultaneously. It seems to do what it wants based on the phase of the moon. 3. The pass through when charging from alternating current is limited to 1500 watts, and apparently if you exceed that, the unit shuts off, rather than cutting charging, which would be less interruptive. 4. You have to power the base station off to add/remove expansion packs. If you're wondering why these things are important to me, the way I'm using this is one base station to power the house during outages, and the other to charge expansion packs with a small generator. That allows me to run the generator about 1/3rd of the time during power outages, and not at all at night. Less fuel and less noise. If it had better A-C pass through where I could use and charge simultaneously with use, it would be a lot more convenient.

Works as advertised, seems to be an excellent product.
