Portable power stations have become almost standard equipment for anglers doing long sessions.
The Jackery Explorer 300 Plus sits towards the smaller end of the power-station market, which actually makes it particularly interesting for carp fishing.
You don’t necessarily need a gigantic unit if your main requirements are keeping a phone, head torch, receiver, camera and other USB equipment charged.
A smaller unit takes up less space and, crucially, adds less weight to the barrow.
Before buying any power station, work out what you’re genuinely going to run.
Phone charging requires comparatively little energy.
A laptop, heated blanket or other high-draw equipment changes the calculation considerably.
Also remember that advertised battery capacity isn’t the exact amount you’ll ultimately get from the AC socket because power conversion itself consumes energy.
For ordinary fishing electronics, USB and USB-C outputs are often the more efficient option.
I’d also keep a power station off damp ground and away from condensation.
Having 240V available in a bivvy doesn’t suddenly make water and electricity good friends.
For weekend sessions, something around the size of the Jackery 300 Plus can make far more sense than hauling a huge power station around.
