Charging devices while hiking

i have a 10,000mAH one, works a treat, will charge a couple of decent phones and a tablet on one charge.

for redundancy/resilience, I'd rather have 3 x 10A ones than one 30A one. I'd also suggest that whilst modern top spec phones are good all in one devices, having a basic phone such as an old nokia 6310 where the battery lasts a week easily and then a seperate GPS using would be more efficient at battery utilisation and if one device runs out you still have the other to either call for help or navigate your way out would be a more sensible choice.
 
I bought the one Margaret suggested a few weeks ago for my cleaner, she doesn't drive therefore she can't charge her phone driving between jobs.
She was very impressed with it so I bought one for myself.
There may be a time I need it when I'm not at home or in my car.
They are very light and take up hardly any space in a pocket and I'm sure they would be easier to cart up a mountain than any fancy gadget.
If making an electronic device for educational purposes was the aim, well done lad.

My phone is the Nokia 6310...the battery charge lasts forever.
Ok it isn't a fancy phone, but I can ring someone and I can send texts, which is all i really want from a phone.

I don't believe that 50Ah, it looks far to small. To many of these devices lie about their capacity. It's a Chinese thing, they write on the box whatever people want to see on the box.

Also with it's stated charge rate of 5V 1000mAh it would take about 3 days to charge from flat

I've just checked mine Neil. It has a more credible 2000mAh. Both input and out put DC 5V 1 amp. Probably true to say it's a bit less output, it must loose something in the process.
It does a good job or recharging the iPhone.
 
Cheers for the input folks,I always carry two old Nokia's (one in the car and another in my rucksack).As you say,the batteries seem to last far longer than the modern devices.

I've also knocked together another charging device from a battery pack off a CB radio I bought using a (£1) 12v cigarette usb charger and I'm planning on using it with a multi usb (it might work :D).At the minute it charges my iPhone at a rate of 2% per minute so it'd take about 50mins to charge fully from flat.

The contraption using TEG's was really only a little project to see if I could knock something together to charge my devices if all else failed and all I had was a stream and flint and steel but sadly it's too heavy to lug about and the chances of that are slim to none :D

I'll grab one of them powerbank devices too (just as a back up),hopefully it'll hold a charge and won't need charging if left for a few days without use and if it isn't too heavy it can stay in my camping kit permanent.
 
What a horribly rough contraption that is and a waste of the battery from the handheld

Have a look at this ebay video to show you inside one of those supposedly 50,000mAh powerbanks is a 4000mAh battery

Surely this item is not 'as described' and you would be right in opening a dispute against the trader....Possibly get a refund.
 
The Chinese who make them don't care about such things. The old saying if it sounds to good to be true it probably is should often be applied. It is a physical impossibility for a unit of that size to contain a 50,000mAh battery at the moment.

Not really a "waste" it came with two when I bought it.
Besides,I've still got it and I could use it but I've wired a small 12v supply to the handheld for when civil unrest hits.
Hopefully that will last longer and the "waste" also doubles up charges my pencil batteries without lugging a big charger about.

Think I'll pass on the Chinese import and go with a uk version ;)
 
Check out the Anker range of chargers AccyX on Amazon. There will be one there to suit your needs.
 
Any that say 50000mAh that are only about the size of a mobile phone are lying about the capacity no matter where you buy it from.

It's the functionality that matters Neil not the numbers. The Anker one I have has one Smart use and two universal. I can recharge ipad, phone and camera if need be all at the same time. 3 times each off one charge. Rated at 1200mAh

You see when you understand these things it makes a difference.
I don't understand them, so I find it very hard to judge if what a seller is telling me is true...and whether what I really need is one with a high mAh spec...the mAh means absolutely nothing at all to me...it just might as well be in chinese.
All I want to know is ...will it effectively charge my device in the absence of having a mains power supply?
If the answer to this is yes, then that will do for me!
 
Aldi have one on their specials this Sunday at £5.99....Ok so it is 2600 mAh(whatever that means - I really haven't a clue.....and anyway if Neil says this may not be the true spec then it really is pot luck).
I don't really need one of these as I rarely use my phone and if I take my Ipad mini anywhere I usually make sure it is fully charged.
But thank you for the information, it might be useful for someone who needs one of these.
