But it was a tenner!Risk burning your house down charging a damaged powerbank to save spending £8 on a replacement ? I can see the Daily Mail headline already

I'm amazed the "Waterproofing" for this power bank is composed of a tightly fitting indented edge all the way around - there's no glue. Whatever the circuit is, seems to communicate with flashing LEDs if there's a fault (short caused by moisture in this case perhaps), so maybe absence of such means it's safe to use? Recycle probably, I've recently discovered there's a lithium disposal facility four miles away, but whether they actually recycle lithium batteries I don't know.I mean, power banks have been around for years and I don't particularly recall a rash of fires (or indeed one single one).
We'll be first against the wall, when the revolution comes...
beef up the cable stick a cell in it and its a hand grenade just flick the switch for a dead short![]()
Northern bans e-scooters from trains and stationsAnd do remember, (some) journalists rarely let truth get in the way of a 'good' story - click bait is the enemy!
Just to say that water has, in electrical terms, a resistance, so technically water ingress won't cause a 'short' circuit........if there's a fault (short caused by moisture in this case perhaps), so maybe absence of such means it's safe to use? ..........
Well, the LEDs stopped flashing for five minutes, off for five, on etc. after it dried out... so given that it was exposed for three weeks to rather a lot of rain water (lead? less so these days, carbon?) which isn't pure, and maybe mud, which may have been further contaminated by some ionic contaminant inside the power bank, could have caused a small current to flow somewhere between some component or other, or perhaps excess moisture affected the electrical properties of some component(s) leading to flashing LEDs? What's your theory? It was only a tenner, I doubt if this power bank contains a moisture sensor - I'll have to take the entire thing apart so we can find out what happened, which I'd rather not do, if it can yet safely be put to its original use of charging up my action camera, tablet, phone etc.Just to say that water has, in electrical terms, a resistance, so technically water ingress won't cause a 'short' circuit.
I've no intention of putting this to a test, but I'd have thought that water across terminal that resulted in a high current would see that same high current quickly heat the water to steam thus eradicating the 'short' - just a theory.......
The purer the water, the better its insulation properties. As a radar mainter of many years past, I remember one particular radar set where the 'final stage' magnetron, which ran at 100,000v, was cooled by pure water being pumped through the device itself.
Once it's fully dried out I am sure it will be fine. They look like nice cells, would be a shame to throw them away.Well, the LEDs stopped flashing for five minutes, off for five, on etc. after it dried out... so given that it was exposed for three weeks to rather a lot of rain water (lead? less so these days, carbon?) which isn't pure, and maybe mud, which may have been further contaminated by some ionic contaminant inside the power bank, could have caused a small current to flow somewhere between some component or other, or perhaps excess moisture affected the electrical properties of some component(s)?

Wow. What the devil was that radar system?The purer the water, the better its insulation properties. As a radar mainter of many years past, I remember one particular radar set where the 'final stage' magnetron, which ran at 100,000v, was cooled by pure water being pumped through the device itself.
Because I'm using Sennheiser HDR-130 RF headphones via the mixing console, the amp keeps automatically switching itself off every hour, hindering the slow drying process. I'll give it a thorough inspection in a few days and will probably just use it, with slight nervousness and initially at least, some caution.Once it's fully dried out I am sure it will be fine. They look like nice cells, would be a shame to throw them away.
you wont get 3 3000mah plus cells in a 10 quid power bank and i bet if you capacity test them wont even be 1000mahOnce it's fully dried out I am sure it will be fine. They look like nice cells, would be a shame to throw them away.
I think that famous high quality manufacturer of totally unfake capacity cells "Litokala" turned up in results, when I Googled "DBK INR2". And capacity seems to be much lower, than before it got rained on for three weeks (judging by it's charging of two action camera batteries and part charge of a tablet).you wont get 3 3000mah plus cells in a 10 quid power bank and i bet if you capacity test them wont even be 1000mah![]()
