You may have heard of the power monkey – instant phone recharger, handy for those emergencies when your phone is ’flat’. They cost about £25 and seem expensive to me even if they are a good idea.
I’ve just found a cheaper alternative – the powerstick. Uses a single AA but manages to output 5.5V – makes it an interesting idea for a range of projects … AND .. the best bit it’s been reduced to £2 (+P&P) from amazon. Worth a look I think.
NB Postage and packing are an extra £6 making £8 all together)
