In reply to Alee | CyclingAbout.com. Yes, fully charged. It is strange indeed. The battery charges with the plug, the Iphone also, so all cables are ok. It just doesn't charge the battery with priority, but the Iphone. When i take the phone off it charges the battery. When the speed drops the battery doesn't take the charging over. Maybe it depends on the type of smartphone and the amperage it needs?

In reply to Metten. Interesting. They must have changed something with the battery because my Flip 20 works as I described. I assume your battery has a decent charge before you plug it in?

I bought the goal zero flip 20 as a result of this article. Finally i thought to have a solution for my problem of failing charge at low speed and the flipping on and off from my Iphone. But at low speed my Iphone keeps flipping on and of because of charging/not charging. I use the plug with a Son dynamo on my Idworx bicycle. Although the goal zero is a pass through battery, it probably passes through the charging power directly to the device and not via the battery when connected. So it CANNOT be used as a buffer to prevent the problem. Nice powerbank, but no solution for the problem. Still looking for a solution 🙁

In reply to Little Devils. The specs would indicate that it's possible. I'm not too sure in practice though – let us know how you go!

You mention the Goal Zero Guide 10 Plus – any idea if this would work directly hooked up to a dynamo through the solar port? As it has a solar port, I wonder if it has some sort of regulator built into it? The specs of this port say Mini solar port (input): 6.5V, up to 1.1A – but how is that achieved if you just plug a solar panel directly into it? I can only think there must be some sort of regulator built into the unit, thus giving me hope I can directly connect it to a dynamo. What do you think?

In reply to Clayton Wangbichler. If you're happy with the way your battery is performing, then just grab an extension cable. Shouldn't add more than 30g to your setup.

Do you find that as simple and reliable as the micro usb method that most batteries charge with? Micro USB are pretty easy to find internationally. Also micro usb charges lights and other devices, so it minimizes the amount of cords you have to carry while bikepacking. Thank you for your input. I’m trying to figure out if I should keep the Flip 20 or go with a different battery.

Hey Alee. Article. Quick question about the Goal Zero Flip batteries. I have a Flip 20 and like the battery, but charging can be such a pain with it. The simple USB charger is nice when plugging into a wall outlet, but difficult (or impossible) when plugging into a Plug III, for example. How do you connect yours to charge while riding? Thank you.

In reply to Alee | CyclingAbout.com. I have to admit, I used to think that the Alfine's Di2 Motor Unit had its own small dynamo.

You can use the SM-BCR2 Di2 USB charger, but companies like kLite can also make a custom circuitry which removes the largish controller box with light indicators. My friend Jesse used kLite to build his dynamo Di2 charging setup: https://www.cyclingabout.com/video-trans-am-bike-race/
