Jackery Explorer 2000 Pro Tragbare Powerstation

I've been test-driving the Jackery 2000 Pro for several weeks now. Here are a few things I've considered or attempted, and the associated results.

- I'm looking for a reliable mobile power source, not something to stay in place. So I took it into a 2000km+ road trip, including some bumpy roads - proper physical shaking. The device has not shown any signs of problems, physical or electrical.

- I've done some tests to observe the sine wave stability, but unfortunately I don't have an inductive load at hand that is powerful enough to exercise its full power range. Still, connecting a 1.1kW electric motor (an air compressor) and then observing the sine wave in an oscilloscope shows it's quite comfortable there (see attached photos).

- To offer the unit's inverter a slightly more challenging environment, I got a resistive load of about 700W in place, and then started an air conditioner that hovers around 1000W while running. Handled the startup rush current smoothly.

- I haven't tested this myself, but I've seen reviews where people overload the device and it still runs for half a minute depending on how much it's overloaded, and then gradually less time the more it's overloaded. That's a great sign for an inverter. It means both that they have confidence the electronics can survive some abuse, and that there's finer control over that abuse. Careful engineering at play.

- To test the DC power inputs, I've connected a 240W/10A constant current power supply on each input at a time, and the Jackery did a great job maxing it out. It hovers between 240W and 241W precisely, around ~10A, so credit to both the Jackery for controlling the charge at the correct power point properly, and to the quality of the power supply for respecting the specs so tightly.

- I've connected 200W and 120W flexible solar panels in a few different circumstances, and compared the performance of the Jackery with a Victron SmartSolar 100/30, and both would rover around the same wattage in the given ideal and non-ideal circumstances. So the MPPT algorithm feels on pair with a respected brand, at least on this lower wattage range. I don't have enough solar panels to max it out.

- The DC inputs are setup in parallel internally, and if you build an adapter, you should be able to output to the two input ports at once, from a single source connector. Assuming it's done correctly, this should make everything run cooler, and make it easier to have a max of 25A without worrying about splitting it up evenly between the connectors.

- The DC power connectors are as bad as everyone says. It's a hard to find connector, and when you do find them they'll be expensive because it's pretty much only targeting Jackery devices which aren't cheap. Searching you can find some adapters at Amazon and AliExpress, and although the options are few, you can just rewire them towards whatever standard you wish, or ask a handy friend to do so for you. Still, while we all know they're doing this to sell their expensive solar panels, they're clearly going to get a lot of people upset and going towards other brands instead, which is a shame as they do a good work on the devices.

- The 12V output port is regulated around 13.2V, and it seems to use a constant current algorithm to prevent overloading. I still need to do more tests around this, though, as I've connected it to a 12V battery, and while it uneventfully charged the battery, the voltage of the external battery was high enough that it didn't reach the maximum output power per specification. Indeed, that's one point to keep in mind: while you can charge external 12V batteries this way, it will slow down dramatically when the voltage raises because this is not a battery charger with a proper multi-stage algorithm.

- I've also tested the 12V output with a number of different appliances within its spec range, resistive and inductive. It all works fine. Indeed, one of the 12V adapters I have is famous for disarming or burning car fuses, because it has too much capacitance and thus a high inrush current which goes to hundreds of watts on kick off. I usually need to connect it straight to the battery to prevent problems. The Jackery worked fine.

- The USB ports work as expected, with nothing to call home about. Fast charging, PD, QC, all together, it just works.

- So called "passthrough charge" works fine. That is, you can charge and discharge meanwhile as desired. To be clear, I never had a device where that wasn't the case, but people seem to ask about this frequently, so I imagine there are poor devices on the market where it doesn't work.

- When using the AC input, the device quickly ramps up to 1500W, and then slowly ramps down after 90%, at the very end going under 300W. I haven't managed to simulate some sort of voltage sag to check if the device can detect that it's pulling too much current from poor wiring or outlet, and ramp down earlier on. Given it ramps up earlier on instead of just shooting for 1500...

Grill, stay warm with an electric heater, power a fridge or a freezer, any power tool, or a speaker system. I am looking to set up an outdoor office with this one also. Charge up super fast from a wall socket, or top up from a car or solar. Could be a little smaller/lighter but is reasonably portable as is
