Best wall wart for Xtar VC4

[H4X0R46]

Hey guys! So I'm thinking of getting the Xtar VC4 charger to charge some 18650s, and I saw that the charger does not come with a wall wart. What would be the best option for that? I have an old Samsung Galaxy charger that's rated at 5v 2amps, will this suffice? Thanks!

You could use any trusted 2 AMP charger or buy the one they sell for it.

I have one of these

5v 1amp. This would be safe to use? Kind of a bummer that Xtar chose to not include the power source for their chargers. Gimmick if you ask me.

Since it is only 1 amp, you'll be limiting the chargers capabilities.
You could easily charge 2 batteries with it but it'd take eons to charge 4 depleted batteries.

Tried using mine with a 1A one.
This way it can only charge 1 or 2 batteries as long as you don't use ports 1+4.
If you do, or try to charge more batteries, it will flash the screen and reset every few seconds.

Just get a 5V 2.1A one.

I would buy the one Xtar sells. I bought one with mine, and it's never failed me.

Sorry I made a typo, it's a 2amp charger. I noticed xtars is 2.1amps. Why the .1?

I'd guess headroom. Never build a device that meets the specifications. It needs to exceed them to ensure safety.

Alright thanks! I'll probably buy the adapter with my VC4. Just to be safe. Thanks!

If the one you already have is 2 amp, you can just use that one.
I only based my answer on your typo.

The VC4 charger requires 100mA for it's own operation and the rest goes to charging.

It's not hard to find a 2.1 wall charger, the Samsung Galaxy speed charger is 2.1

I didn't even think to account for the device itself! That's good to know!

It's got LEDs, a screen and a circuit to operate.
