ChrisF Posted February 18, 2022 Share What do you use to charge your cycling computer on long rides ? I often top up the battery from a battery bank while having coffee, during longer rides. I am doing longer MTB rides this year which may well take longer than the time my 520 allows for. I am considering a head light shaped battery bank, fixed to the bars with a head light bracket ... Would love to hear what you use. Pictures welcomed PS - I did search but could not find an existing thread about this. Link to comment Share on other sites More sharing options...
BaGearA Posted February 18, 2022 Share Anything cylindrical should be good cause then you can strap it on one of those cheap cycling light brackets on the bar and run a short cable to the gps ChrisF 1 Link to comment Share on other sites More sharing options...
Tatt Posted February 18, 2022 Share Hi Chris Have you considered a dynamo hub, it might be an option instead of taping a big battery to your bike? https://www.bikeradar.com/advice/buyers-guides/bike-dynamos/ How much life do you get out of your 520, my Giant has over 30 hours life which I generally find pretty ample?

Tom I only need 1 or 2 hours extra out of the Garmin. And then only for a few rides per year. For regular ultra distances the dyno probably has its market.

Ooooo Murphy ..... I prepped and tested my equipment for the Trans Augrabies. Including a cylindrical battery bank and a "cheap cycling light bar mount". Worked very well to keep the Garmin going for the longer rides. Similar to this - I have to remove the unit from the bar to charge it .... Fitting it for day three ..... the cheap bar mount strap breaks. Thankfully I could stretch the heck out of it and hook onto the next segment .... but this cant last too long. Where to buy more of these bar mounts ? Ideally something better .... (or cheap enough to buy a spare) Link to comment Share on other sites More sharing options...

They sure have a WIDE range of products. Can it power both the garmin and GoPro at the same time ? Or rather, do they have a model with two outputs ....

Or rather, do they have a model with two outputs I’m trying to find it. It’s been a while since I’ve used it, and it’s not in my box with other cycling stuff. It’s either been placed somewhere in the house, or… discreetly removed from the house without me knowing. edit: found it in shoe box (long story). Model number RG40 Has two charge points, - one USB (Garmin charge cable can plug in here) - one mini-USB to charge GoPro. 4000mAh (so relatively small in battery bank sizes).

TyronLab Posted June 25, 2022 Share I've thrown a normal power bank into a frame bag. You can pick up relatively cheap frame bags that can carry the rest of your riding paraphernalia too. Not sure how accommodating your frame is. ChrisF 1 Link to comment Share on other sites More sharing options...

This frame only has space for a top tube bag. The fit between the Garmin and the bag is not nice .... with sharp turns I got alarms from the Garmin that the charger is disconnected. On my hardtail I regularly use a frame mounted battery to charge the Garmin. But I need a bar mount for the blue bike ..... Link to comment Share on other sites More sharing options...
RookieSports.co.za Posted June 26, 2022 Share Use a bicycle light that has a large battery and USB out. Dual function and made to fit you handlebar. 4000mah battery with USB output: https://www.rookiesports.co.za/product/fluir-ultra-720lm-front-bicycle-light/ 4800mah battery with USB-C output (you will need a USB-C to normal USB cable for this light): https://www.rookiesports.co.za/product/fluir-elite-1000lm-front-bicycle-light-usb-c-rechargeable/ ChrisF 1 Link to comment Share on other sites More sharing options...
117 Posted June 26, 2022 Share Is your Garmin old that it won't hold a charge for more than 6 or so hours? By the time you're said and done with brackets, battery packs, cables, bags, clamps, cable ties, o-rings on the bike and extra stuff to charge over night, you're probably better off getting a new Garmin unit You're welcome to use my lezyne for the ride, holds for about 50hours between charges 😉 ChrisF 1 Link to comment Share on other sites More sharing options...
ChrisF Posted June 26, 2022 Share 520, think I bought it in 2017. This is the reality when we buy into an eco.system .... watch, cycling computers, etc all Garmin. For now it will be the light-battery pack for that last hour on long rides - specifically MTB. Not doing enough of those to justify a new computer ... not yet. I am sorted on the road rides, which are the bulk of my longer rides. 117 1 Link to comment Share on other sites More sharing options...
