I have written about ultralight USB cables and this really miniature usb lamp but had you ever wished you could light a fire with your power bank? Now you can. Mine came free with the Hand Dynamo I just wrote about. You can buy similar ones from Aliexpress here and here for between A$2 and […]
Litesmith have recently utilised the 21700 Lithium battery to make perhaps the most compact and lightest (at 73.5 grams) 5000 mAh power bank. These batteries are available to 5800 mAh so expect some improvements still.They are selling for US$22 (Sep 2023). This size should allow you to charge (once) the largest mobile phone around (usually
The 14.8 gram 650 lumen glow in the dark Awesome Flashlight I wrote about recently which can be made into a head torch like this can also be converted into a cap light by using the supplied 1.9 clip. This A5X model is absolutely brilliant. You could just use the side LEDs (without the silicone
I will be using the Nano A5X (glow in the dark) 14.8 gram 650 lumen rechargeable torch for this mod though the pictures here are for the A1 which I already own (which is a whole gram heavier and does not glow- alas!) I have often added a simple O-ring, a length of 1mm dyneema

These ‘Nano’ rechargeable (lithium) torches are quite amazing. I thought I would try the A1X (weight 16.8 grams = 650 lumens) just to see how it turned out and I must say I am delighted. I will probably buy a three pack now of the A5Xs to go in my hiking pack as my go-to
Nitecore’s NU25 rechargeable torch is very hard to beat – though no doubt it will be (by their next model). It weighs around 28 grams without the band (which weighs another 23 grams). You can save 22 of these grams (as I have done here) by fitting a piece of dyneema cord and a micro-cord
I have been using these fob pocket sized phones now for about three years – and would never go back to a larger phone. The first one I bought was the Unihertz Atom which I carried for a couple of years. Practically all the photos I posted for the last couple of years here at
These are an interesting emergency light at 2.4 grams each. They plug straight in to your ultralight power bank. Some of them have a touch switch and are even dimmable (eg the Yitee one – quoted above). They are not as energy efficient as these 11 gram rechageables but would make a good spare, or
What a great new head torch I managed to pick up from Deal Extreme for under US$30! Equipped with a CREE XP-G3 S3 LED, the NU32 emits a bright 550 lumens extending out to 125 metres/408 feet. In addition to this primary LED, which offers four different brightness modes, the NU32 also features high-CRI auxiliary
Although they are not (at present) ultralight, I really like the concepts behind these wonderful lamps.
