Ultralight Hiking USB cables, etc.

This is my tiny bag of cables and other electronic goodies. The cable (17 grams) is only 6″ (15 cm) long and comes with interchangeable tips (5 grams each). Shown USB, micro USB (x2) and Sat Phone charger plug (comes with, so total = 27 grams) – this will get all my hiking devices charged on the trail: phone, camera, torches http://www.theultralighthiker.com/11-gram-rechargeable-head-torch/, sat phone, sat messenger, or etc). Also see below it a 5 gram white USB/Micro USB SD (& micro SD) card reader – great for sharing files on the trail (eg someone else’s photos. Also a couple of spare micro SD cards and adapter/s and a 3 gram case for extra photo etc storage – just in case I get the opportunity to make a movie about Fiordland moose! Note to self: I can save 4 grams here! The solar set-up below can recharge  a couple of AA/AAA batteries and all these devices as I walk along.

NB: Solar charging http://www.theultralighthiker.com/powerfilm-usb-aa-solar-charger/ (well charging in general) did not work at all well at high altitude (as on my Everest Base Camp trip), though it works fine at home in the Victorian mountains (never above 2,000 metres), and usually much less – there will be a future post about this, but to cut a long story short; everyone’s batteries discharged (even when not in use) at at least twice the normal rate in Nepal, eg: http://www.theultralighthiker.com/i-saw-below-me-that-golden-valley/


Cable inc sat phone tip 17 grams

2 x micro USB tips 5 grams ea

USB/Micro USB reader 5 grams

3 micros SD cards, adapter, case 5 grams

Cuben stuff sack 2 grams

Total 39 grams.

I bought the cable and adapter tips from these folk: http://www.tekkeon.com/products.html

They also sell this interesting AA charger: http://www.tekkeon.com/products-tekcharge1580.html 125 grams Uses AA alkaline or rechargeable batteries TekCharge MP1580 doubles as a battery charger, so you can charge your rechargeable NiMH or lithium batteries as needed.

They also have a number of power banks such as this one: http://www.tekkeon.com/products-tekcharge1820-specs.html 125 grams for 4800 mAh

This is a reasonable weight for a power bank (I will also have a later post about them), but my spare battery for my Samsung Galaxy S4 camera weighs 35 grams for 2900 mAh, so about 15 grams per each amp hour. At that rate of conversion a 4800 mAh power bank should weigh less than 90 grams! I need to walk around the city sometime with an electonic scales in my posket weighing these ubiquitous little guys. I have done very poorly searching eg for ‘lightest power bank’ on the net. Good luck with that! But, if you have better information, please let me know.

I figure you need a minimum of approx. twice the capacity of your phone, so likely over 6000mAh. This would need to weigh (much) less than the above solar setup or this lighter version, the Bushnell Solarwrap Mini: http://www.theultralighthiker.com/charging/ which can be cut down by about 7 grams and still attach to your pack (as above) so will weigh < 80 grams for 1,000 mAh, plus whatever the sun delivers!
