“When I saw it it looked like the battery was all in built in the head end but it's inconveniently down near the pump end, good if the lead was longer. Or inbuilt or removable like a cordless power tool.”
“Bought one of these recently and partner & I used it camping a couple of weeks ago. Gives plenty of water to shower and wash hair etc. but not too fast to drain the supply too quickly 10 litre bucket gives a good shower and hair wash in comfort
The only thing I can see that would make it better would be the on/off switch mounted in the shower nozzle handle for easier control.”
