Dual voltage power bank for iPhone?

I would verify that you are correct on the one you have. Just about any power bank I have seen is dual voltage. First, how do you charge it? Does it have a dedicated cord, or do you plug a USB charger into it? If you use the USB, then any USB charger works and is dual voltage. If the power bank has a dedicated charger, then on the part that plugs in, it should indicate input voltage, if it says something like 110V - 240V, you are good.

I have not seen any phone chargers that are not dual voltage, EVER. A plug adaptor is all you need.

I bought a UK adapter that also has a usb slot. It's very handy. No converter is needed.

After a frustrating experience on my last trip using my various adapters/plugs, I came home and bought this Anker Nano charger. It has two USB C, two USB A, and one AC plug. The device has multiple adapters that work in the UK and Euro plugs (plus others) https://a.co/d/9S2u5l2 As a bonus, it's much slimmer than my other multi-plug adapters and folds flat.

I don't think I explained well what I'm looking for. I'd like to have a power block/bank that I would take with me every day to use if the charge on the iPhone gets low. I'd plug the phone into this, and charge it. Not an adapter, or converter. Ideally, it would be one that is dual voltage, so when I need to recharge the power block/bank, I can plug it in directly without a converter.

Hi, gmckel52,

As the others have said, just about every electronic device out there (including power banks) and are all dual voltage, so all you need is an adaptor. I have an Anker power bank that charges my phone quickly, and I like it a lot. Anker makes a very good power bank and you can't go wrong buying one of their products.

With regards to adaptors, I like to be able to charge more than one device at a time, so I purchase adaptors like this one: https://www.amazon.com/dp/B0CBTDS95J/ref=dp_iou_view_item?ie=UTF8&th=1 This is for France, and I like it because it has 3 outlets, 2 USB-C ports and 1 USB-A port. It's also more packable as the prongs fold down. It's also a 2-pack.

For the UK, this is similar, except the prongs are not foldable (difficult with the UK electrical setup). https://www.amazon.com/dp/B0C27DSWHB?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_1&th=1

Anker is what I have, although mine is a couple of years old, so you may want to find a newer one. And as I mentioned, EVERY electronic device out there today is dual voltage. I promise you that.

I would suggest shopping for one on Amazon (just key in "anker power bank") or check CostcoNext, which frequently has good deals on Anker products (if you are a Costco member). Or you can just go to the Anker website and look there. Here is a link to their collection of power banks. https://www.anker.com/collections/power-banks Belkin also has good power banks.

If you're not sure what you want, you could always go to Best Buy and talk to someone there. Keep in mine that the higher the cost, the faster you will be able to charge and the more data it will hold. But that comes at a price in that it will be heavier. You can get lighter ones like the Travel Card Charger that are about the size of a credit card, but probably won't hold much charge.

Here is an article that explains what you should be looking for. https://www.ecoflow.com/ca/blog/best-power-bank-for-travel I would suggest getting something between 10,000 to 20,000mAh. Also, keep in mind that you cannot put a power bank in a checked bag. You must carry it on, and it generally can't be higher than 20,000mAh.

I obviously didn't understand what you wanted, sorry. This is what I have for recharging my Android device. Assuming you have a newer iPhone with USB-C charging port, it would work for that. https://a.co/d/7PNohgk

I bought this a few months ago. It's lightweight and comes with a charging cord that doubles as a "leash" for the device. It works great.

You can charge it anywhere and it has one USB A and two USB C connections.

Or do you mean something like this that plugs directly into the wall socket?

or

A plug adapter is needed for both.

Amazon has plenty of choices.

The device CL linked to would also work.

Thanks, everyone, for all the great suggestions! I think I've found what I need. Thanks again!

I have what CL uses for my iPhone. I like that it can be charging while the phone is in use.

I have never seen a phone charger that was dual voltage.

Dual voltage is a configuration that is rarely used today. It is where a heating appliance is made to work on two voltages, one twice the other, like 115V and 230V. It was used for hair dryers or curlers, where the multiple heating elements were built for one voltage, say 115V, and configured in parallel for a 115V power source or two in series for a 230 power source, with a switch to select the input voltage.

Today's devices are actually multi-voltage. They don't need a switch. They can accept anything from 100V to 240V (and probably more). They use a transistor to limit the output to 115V for a US plug or to 5V, rectified to DC, for certain devices (i.e., USB) chargers.

Dual voltage (230V to 115V) power converters used to be common, like in the early days of this century. At that time they were 2:1 transformers and got very heavy if you wanted a 1.6 kW one to use with a hair dryer. They still make small ones for 40-200W for electronics that don't use a USB source. The wave form from transformer is better for electronic devices. For everything else, high wattage, they use transistorized voltage converters which do take any input up to 240V and probably higher except that's the max anywhere in the world. These are multi-voltage devices, not dual voltage.

this simple question was asked and answered 16 days ago, and the last entry was 3 days ago yet it keeps rising to the top, like somebody is changing spacing or some other trivial edit to keep it at the top.

Anybody know who is making all the changes?

I have one already, but I would need a converter to use it.

You only need a converter if the power bank says that the input is 115VAC (only) or something similar, as 110 to 125V, and I don't thinks I've seen anything like that, at least not for many years. A lot of power banks are charged via USB, which by itself doesn't need a converter (a USB charger is a converter).

If it has a high voltage (like a US 2 bladed) plug, look at the nameplate, if it says 100V-240V, you don't need a converter.
