ubs chargers

I cannot see on either of these what voltages they cover. It must be 100-240 V 50/60 Hz if it is to work in Europe.
If you already have an adapter plug, why do you need to buy a new charger, why can't you use your existing charger with the adapter?

Or plan B, buy a charger when you get to wherever you are going, then you know it will have the correct plug (no adapter needed), and work with the correct voltage.

Thanks Chris,
I have the European plug, but want at least a 2 port UBS charge for convenience. Neither is a converter which I do not need.

I'm just about to pull the trigger on this one in my Amazon cart. It's been recommended by a number of people in other forum threads on this subject.

I saw the posts but techno-phobe that I am I couldn't figure out the difference between 1A port and 2.4A port. Can anyone explain? It sounded like 1A is for notebooks but we're not taking those. Is my assumption correct?
Sorry to be ignorant but it's a long way from home if I guess wrong.

I couldn't figure out the difference between 1A port and 2.4A port

The more Amps you have, the faster things charge. But some things can only take 1A, so it doesn't matter. Other appliances have bigger appetites, and with 2.4A get full quicker.

P.S. It's USB. UBS is a Swiss Bank.

I have the 4 port version of the Anker.

2.1 Amp (or 2.4) is needed for tablets. 1.0 A is fine for cellphones.

Go with the lighter one.

Why bother with a converter when it is not needed.

We used the one that stoutfella linked. It works everywhere we travel and charges multiple devices. Excellent purchase!

I use a 4 port version of the Anker. Works fine for a phone and tablet. When traveling with someone I have enough ports for both of us. Occasionally I end up in a hotel room where the only open outlet is blocked by a headboard or some other piece of furniture. It's nice having a short extension cord in these situations.

I've been happy with this one: https://www.amazon.com/gp/product/B0191GVDKE/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
The plug(s) are an integral part of the unit and easily swap out.

I recently bought the Syncwire charger that was suggested in Stoutfella's post, and I've been very happy with it. I can charge two iphones and 2 ipads at the same time. (The ports marked 1A have the right output for the iPhone and those marked 2.4A have the right output for the iPad). It comes with outlet adapters.

I have the Anker dual-port USB wall charger linked in the original post. I purchased it in September. Two months later, it started sparking from the wall prongs so I called Anker and got a brand new free replacement within 3 days. I've had no problems with the replacement charger thus far.

I like that the Anker wall charger charges my iPhone faster than the Apple wall charger that came with the iPhone. I use the second port to charge (when necessary) the Anker lipstick charger that another poster mentioned. I've been very happy with the lipstick charger--it doesn't weigh much or take up much space and for long travel days it's good peace of mind. I also put my iPhone on "power save" mode when out and about to preserve the battery.

Good luck with your purchase

The plugs we have for our android phones and iPads are labeled for 110 & 240 volts, meaning they work on US and European voltages. We simply take a plug adapter and an extension cord that has multiple plug-ins (outlets). It works just fine without having to buy extra equipment. But I can see where carrying one 4-outlet plug would be less bulky than taking the bulky plug for 4 devices. Either way, I would still suggest, as mentioned in an earlier post, that you take an extension cord for those times when the outlet is blocked by furniture or in an awkward location. Enjoy your trip.

I carry a few Retractable USB extension cables. They take up a lot less room than a regular extension cord.

The adaptors recommended in this forum accept USB plugs, but I have a camera battery which does not have a USB cord. It's an ordinary US plug. Suggestions?

TIA!

Patty, you say "It's an ordinary US plug", does it then go into some sort of charger that you place the battery in? What does it say on this thing (in the small print)?
If it says "110/240 V 50/60 Hz AC" you are OK, you just need a plug adapter.
If it just says "110 V 60 Hz AC" you will fry your battery if you use it, you also need a voltage converter. But, it would be better just to buy a new battery charger.

The camera battery is dual voltage. But, it's not a USB - has a "regular" US plug. The recommendations I've seen on the RS forums have only included USB adaptors. I'm looking for a rec for a converter that accepts both USB and plugs.

Patty, we have a terminology problem.
Batteries are never dual voltage. Batteries are not 110V and are not 220V, they are usually a small DC voltage, for example 5V DC or 9V DC or 12V DC.
The charger converts from whatever comes out of the wall (110V 60Hz AC in North America, 230V 50Hz AC in Europe) to whatever the battery needs.
USB is 5V DC. If your charger is not USB, then either what you call the plug, or whatever you stick the battery into, is converting to whatever the battery wants. You need to look at this, and look at the small print, to see what voltage(s) it accepts as input.
it Is 90% sure it will accept 110-230V 50/60Hz AC, in which case all you need is a plug adapter, not a voltage converter. Saying it is not USB is a red herring.

Why bother with a converter when it is not needed.

In fact, a USB "charger" is a voltage converter (multi-voltage, 100V-240V AC in to 5 VDC out). You can't plug an iPhone directly into a 120VAC wall receptacle in this country or a 230VAC wall receptacle in Europe. You need a voltage converter (its charger), and that is what your USB charger is.
