advice please for a novice

I am targetting a 3 or4 week tour ... next year . My first one!

Carrying an iphone for pictures and an ipad for text updates to my journal

Clearly i can recharge both of them at my overnight stops ... not camping 

But if i was carrying a power bank .. a midday top up of phone is possible

Now regular contributors...... Any advice for  a specfic model to carry

THX for any input

I'd suggest looking at the Anker products. Mine have held up well. Model depends upon what you anticipate needing and how you want to attach to your phone. 

I too have been happy with my Anker powerbank. If you’re just needing one for a possible mid day top up of your iPhone, then a 5000mAh model will be compact and light and give you all the power you need.

One thing to consider with your power bank is its ability to charge while being charged. I find that power banks can take a long time to charge and it is nice to be able to charge other devices while the power bank itself is being charged.

Mine doesn't do this, which is why I am aware of it.

does this indicate a specific make to avoid  or is it be aware and remember this if buying new

The ability to charge the power bank while it's charging another device seems like it would only be needed when using solar power to charge the power bank.

When AC power is available it makes more sense to charge your phone directly using the phone's AC powered charger.

For tours over the past few years I’ve taken a 10 megasomething  Belkin power bank. It’s been more than sufficient to charge my phone and rear flashing night on the rare occasion mains power can’t be accessed for a day or so.

I do use my phone for photos, navigation checks and journaling. However I’m careful to conserve battery charge on the phone to avoid having to charge it during the day. That is, keep it switched off or on flight mode if necessary.

My newest widget is a Garmin bike computer. It runs for days without needing to be charged. So it takes some of the navigation workload off the phone.

Our airlines are becoming increasingly wary of power banks following recent fires on board. The current requirement is that the powerbank be in arms reach and not used while on board.

To overcome the issue of powerbanks not charging while being charged, get an adapter with two outlets. Or carry two adapters. They are very light.

The power bank I have uses a USB charging cord. I usually tour outside the US, where I live. Thus, I need USB chargers using different plugs than I have at home. I carry 2 of these, but I carry an iPad, iPhone, USB charged lights, USB charged wristwatch, as well as, devices that need to be charged directly (camera batteries, beard trimmer). Also, in my experience,  power banks take a fair amount of time to recharge.

I often have to manage the order in which I charge of my devices so that I don't have to wake-up in the night to change them over. I could buy more USB chargers I suppose, but two work for me. Since I don't camp and have access to electricity every night, this isn't a huge problem normally. It would be easier if the power bank could charge while charging.

I would suggest that it is a feature to look for. I'm not well versed in the current power bank market, so can't give specific advice on brand or make.

Congrats on taking on a tour! I've completed a number of day-long rides. I've developed a system that works for me to keep my phone, Garmin watch, and Garmin bike computer charged during multiday trips. 

My setup is a Rock Brothers handlebar bottle/snacks bag for holding a charging bank. I connect a charging cord from that to my handlebar-mounted phone. If I'm often taking photos, I'll put that in the bag also for quicker, easier access.  

I use two charging banks. My favorite is the Anker Power Core 5000mAh.  It is small and lightweight, and I'll often carry in my coat or pants pocket (and attached to the phone) when I'm walking around town at the end of a bike day. It doesn't hold a LOT of power, but I've found it enough to recharge my phone even on a long day.  Note: if you record a lot of videos during your ride, or if you're doing a century or a long day, the Anker 5000 may not get you through the day. I've never tried it on my iPad.

If you have a compatible phone, the Anker 633 magnetic charger battery with flip stand (10,000mAh) has worked really well for me.  It's a bit heavy, and can get hot with extended charging. It's also a bit costly - there may be less expensive ones on the market now.  You can charge your iPad with it also.

Finally, for my multiday trips I also carry an Anker 2nd Gen Astro E5, with 16750mAh. Looks like it has been superseded by updated products. I like it because it has multiple outlets enabling my to recharge two items.

Generally I try to charge up my phone, watch and computer when I'm done biking for the day, an charge through the evening. Then charge the batteries overnight. Also, one of my tricks is to find a charging outlet at a lunch and/or rest stop, and get even 10 or fifteen minutes of charging.
