Power Bank advice

trickydicky14

Need some advice please,
I use a Satmap hand held GPS which is good but very power hungry.
I do a lot of long- distance walking and running and intend to do a 100 mile event soon and need the GPS to navigate for up to 40hrs.
The LiPol battery in the unit would need recharging several times during this event and I was thinking of purchasing a power bank would this be a good idea if so, what would you recommend.
Asking a lot but it would need to be light, powerful and transfer power quickly.
Some advice would be great.
Thanks

Anker.



Get one direct from Amazon, not a marketplace seller or ebay, as there are fakes around.

Transfer power quickly, that will be down to your device, almost all powerbanks will put out enough power to kill your internal battery in a few charges.

Rapid charge it at extremely high currents.

Buy spare batteries for the device?

Even the most efficient charger will still waste power charging your device.

Which model Satmap do you have, how old is it and what is the capacity of the battery? Do you have a budget for the powerbank?

I would seriously first look at how old the Satmap's battery is. If it depletes so quickly, is this something that's just started happening and gradually becoming worse? If so, replacing the battery should be your first move.

Something to bear in mind is that constantly draining batteries and recharging them is very unhealthy for them. If the device allows you to use it while being charged, I would also consider a long USB charging cable to connect it to a powerbank that you might perhaps keep in your rucksack?

I doubt you'll use the full capacity of a decent 20,000+ mAh powerbank over a few days, unless you charge your phone with it too. But will you have stopping points to charge the powerbank, Satmap and other devices during the night? If not, you would be wise to look at the biggest capacity powerbank you can afford.

I like EC Technology powerbanks - you get a lot for your money, but no compromise on quality. Their largest capacity is this 26,800 mAh.

Humans have managed to find their way with maps for at least 4,000 years, the invention of GPS doesn't invalidate that ability and I suggest that the OP follows Chino's suggestion at post #3.

The other thing to consider will be whether you can use the device while charging, some won't. In which case you'd need to plug it in whenever stopped (100 miles is including sleeping I guess?)

Humans also used to travel long distances without any form of mechanical transport to help them so I assume that you're not hypocritical and you have a horse instead of a car.
How about cooking your food? Do you use an open fire?
After all, why would you want to use an invention that makes life easier such as a gas or electric cooker?

I would second the Anker recommendation above, combined with a coiled USB cable, which will prevent the cable flapping about whilst giving you flexibility in your GPS' carrying position (assuming power bank in your rucksack on your back, GPS secured to your front).

The unit wont need to be powered for 40 hours though will it?

Turn it on get the directions/reference then power it off.

All very good suggestions but it depends on the event. My sister is running the Spine Challenger this weekend and has to have a kit check the day before. If you don't have a suitable GPS they won't even let you start the race.
