Can you leave a power station plugged in all the time?
TroubleshootingUpdated 2026-08-08
Yes, mechanically: every machine here will sit on the wall and pass power through to whatever is plugged into it. The two things worth knowing before you rely on it are how long the output actually drops when the grid fails, and that the input socket has a ceiling your load shares with the charger.
Switchover time is published on 9 of 12 of the machines here, and it is not the same number on all of them — the values range from 10 ms to 20 ms. Several manuals say plainly that the feature is not meant for equipment that cannot tolerate a break at all.
Every figure here is the manufacturer’s own, from a manual or a spec page, with the verification date on the row. They are stated CEILINGS rather than measurements — the records say so in their test conditions, and several are written as "≤" in the source.

Three distinct values across four brands is more spread than this category usually shows, and the interesting part is not which is fastest. It is that 4 of 12 records state the topology at all, and every one of those that does calls it offline — the inverter is not running your load until the grid drops. That is what a switchover time IS: the gap while it starts. A supply with no gap at all would have no such figure to quote.
Why charging slows down when you plug something in
What the AC input socket is rated for
The published maximum AC charging power on four records. On several of them the same socket also feeds whatever is plugged into the outputs, which is where the "it charges slower when I use it" question comes from.

The smallest input here, and the clearest illustration: the same manual gives a higher number for the socket once bypass is included, because charging and pass-through share it.

Two of these manuals publish the distinction explicitly. The Elite 30 V2’s AC charging figure is the charger alone; its socket is rated to 980 W once bypass is counted. The Elite 100 V2’s manual makes the same split, and its charging-plus-bypass ceiling lands on the same number as that machine’s own continuous AC OUTPUT rating — which is worth not misreading as one figure quoted twice. Both are bounded by what an ordinary 120 V branch circuit will carry, which is why the two sides of the machine meet at the same ceiling. So a kettle on the output does not merely add to the total — it takes its share out of the same rated input, and the charger gets what is left. That is the whole mechanism, and it is why a machine that charges in an hour bare can take all evening with a fridge hanging off it.
Does leaving it plugged in wear the battery?
This is the most-asked half of the question and the half we decline to answer. We have found no published statement from any maker in this library about continuous float, no measured capacity fade under permanent mains, and no guidance on whether time on the wall is counted against a cycle rating at all. What the records do carry is a cycle count and the retention threshold it is counted to, which is a different question and is worked through elsewhere on this site. An answer built out of what we hold would be an answer about cycles dressed up as an answer about float, and that is the kind of substitution this library exists to refuse.
Can you leave a power station plugged in all the time?
Mechanically yes, and every machine here will pass power through to its outputs while charging. Whether permanent mains wears the battery is a question we have found no published maker guidance on and hold no measurement of, so this site states no answer to it.
Can I use a power station while it is charging?
Yes, but the AC input socket is a shared ceiling on several of these records: the manual gives one figure for charging alone and a higher one for charging plus bypass. Whatever the outputs are drawing comes out of that same rating, so the charger takes what is left and the machine charges more slowly.
How fast does a power station switch over in UPS mode?
Nine of the twelve published US machines here state a figure, and it is not the same on all of them — three distinct published values across four brands, every one of them a stated ceiling rather than a measurement. Several manuals add that the feature is not intended for equipment that cannot tolerate any break at all.
