Hello.
We have a Jackery Explorer 2000 Pro power bank. It has 2 x AC outlets. When it's switched on, it creates a lot of electrical interference with wireless devices, such as DAB radios ...etc, no matter where they are in the house. It knocks them out and they can't get a signal. There doesn't have to be anything plugged in to the power bank for it to create this interference.
I suspect that grounding the power bank would solve the problem, but what would be the best way to do this please?
Had to look that up it's a beast!
It's portable and built solid by the looks of it else I was going to suggest hanging wire from a bolt or something and tie the other end on something nearby that's metal (perhaps metal gate or something that's fixed in the ground).
Do you know if it's a common problem with them in general? I'd guess they all do it a bit.
Another option is to earth the dab radio somehow? Is that in a vehicle?
(I'm not an electrician by any stretch I just make the forum tea when asked)

Hi Dan, and thanks for responding.
Yes, these power banks are really good devices and very handy to have, but the electrical noise from ours is hopping onto the mains wiring and causing reception issues with wireless gadgets in other parts of the house.
We have the power bank in the house to use when we get a power cut and we're aiming towards going off-grid eventually. We just need to find a means to power the washing machine!
When searching for answers to the noise problem, I've found that it's quite common with these power banks. I read on a Facebook forum that someone was having similar problems:
“Hey all! I have a Jackery 1000 Plus battery inverter portable power station and when I plug in a Fender tube guitar amp, I get a lot of noise from the speaker - before even plugging in the guitar etc.
Any tips for reducing noise? Maybe there's a way to bond/ground the system by driving a stake into the earth? The Jackery doesn't have a case ground or bonding point like generators do : ( Or maybe its inverter noise and a power conditioner of some sort could help?”
This guy didn't appear to find a solution to his guitar amp problem.
