Question: How do Wasabi battery can be loaded using this Wasabi Power if output Volts are less then Volts required from battery ? Thanks.
Document: extra batteries to power my Cannon while on Vacation i made a great choice getting these extras batteries, thanks wasabi,
In fact, you could buy two of the Wasabi Power Battery (2-Pack) and Charger and end up with two chargers and four batteries for less than one LP-E8 Canon battery costs.
After reading and checking almost all similar products and their reviews, I decided to give an opportunity to these Wasabi batteries. Also, they get completely charged in less than 2 hours, using both the official Canon charger and the one that comes in the package delivered.PROS: I received the newest model with 2000mAh! (which is nearly the double of the original Canon battery) and the charge is great using with the Photive Grip for Canon EOS Rebel models.
The battery charger is set for240 volts.It only charges to about 1/2 or less on120 volts.This is so the same charger can be used with both voltages. I presume that it will charge fully with 240 voltsIt definitely does not charge fully with 120 volts. **I had the same thing happen with a small one cup water heater designed for 240 volts. It does heat but poorly with 120 volts.When I purchase a product in the USA I want it to work properly on our voltage.
The charger works fine and automatically adjust s between 110 and 220 volts. As for the batteries, the charge does not last as long as the Canon brand. But the price is so much less. I use these as backups. I always carry extra batteries with me just in case. And this fits the bill well and the price won't break your wallet like the Canon brand.
These arrived about 3 days after I ordered them (I love in Maine). I haven't had a chance to really test them yet, but given some of the reviews I may not be surprised if the chargers aren't the best. But I have charger. I just wanted spare batteries and these were a steal! I have used Wasabi Power before and loved them, so I'm looking forward to using these!
Great price and so far a great product. Good to have spare batteries and using these in a third party battery grip on my Canon T3i. These babies hold a charge for quite some time. I charge them mostly out of habit... never had one go down to an unusable state. Good product and much cheaper than OEM. Thanks!
Before (Slightly) upgrading to a T3i I was using a D3100. While in Orlando 2 years ago I needed another battery, I spent $47 purchasing a battery in one of the million strip mall Camera Shops with a guarantee that it would work on the D3100. The are two different EN-El 14's. One without a chip and one with, which is required for the D3100.
They are cheap knock off batteries, they don't last as long as the canon batteries, but two and a charger costs less than half of a cannon battery. Been using them for almost a year and they hold their charge pretty good. You get what you pay for. And definitely worth the money
Holds a charge less than an official Canon battery but, you do get two of them, with a charger.I'm not sure if the chargers work on the standard canon batteries. I had a canon battery plugged in to it for over an hour and didn't seem to get it anywhere. But the wasabi batteries charge pretty fast.Overall this is a great deal, good batteries. These are the batteries that you would use as a back up and not your primary. Especially if you do video.
Answer: Hello, if I understand you correctly, the output voltage is less than what is required? Maybe a defective battery.. Although,  dual voltage rechargeable, 220\50htz, may be the problem. The same with 110/60htz as well. So, it could be the charger. I have had zero issues with mine. Check the component that your using them on too... Hope this helps.
