Poundland "disposable" phone charger.

Yet another of the single use chargers with a fully rechargeable cell inside. This one takes it one step further with a full power bank chip. It's literally just missing a resistor, capacitor, LED and charge connector to make it a fully rechargeable unit.
But on a plus note it can be used as a cheap and easily available source of 500mAh metal cased lithium cells if suitable cell protection is used. Or if you patch in the extra components you can recharge it from a USB power source.
This unit represents very poor value compared to even the most basic Poundland powerbank. The only advantage is its slim size.
If you really need a powerbank for a festival I'd strongly recommend a proper high capacity unit.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
