Raeisusp 5V USB Cable ACK-DC40 + DR-40 DC Coupler NB-6L Dummy Battery for Canon S90 S95 SX530 SX600 SX610 SX700 SX710

Perfect for the camera. Should work well with a power pack, will have a much longer battery life.

Works fine so far

I plugged it into an Anker 2.4A USB power wart and saw the camera side power output read 4.14V at 2.4A; precisely what it should read. Safe to say, a safe converter from USB for the camera. The jack (on my Powershot S120) fits very tightly into the access hole under the rubber flap; so tightly that, #1 I didn't get it all the way in on first try so I thought it did not provide power, & #2 It's difficult to remove, which means it won't fall out by accident. (Note for other people ordering from this business: A good experience. Ordered on Jan 14th and shipped in China on the 15th. Although Amazon tracking indicated it had been in California (from China) since the 22nd, to be delivered by Feb 5th, apparently it was reshiped from California by another hand and Amazon lost track. It arrived in the mail unexpectedly on Jan 29th.)

I was able to leave my Cannon recording until the SD card got full. I'm happy.

You have to open up the rubber flap in the battery compartment cover however it appears to work fine. Especielly whan using the camera indoors or on the bench you know the camera won't stop because the battery has gone flat

Works great, make sure you plug in tightly

Ground not connected on socket of dummy battery, I have to solder connection. Otherwise voltage is correct for camera. Probably dummy battery not tested before shipment.

Works well, but the plug does slip out of the adapter easily, and the adapter slips out of the camera easily. So take caution that nothing could slip, and it's great.
