Rayovac 2-Hour Power Mobile Charger Review

I received this product for the purpose of this review. All opinions stated are my own and may differ from yours.
Rayovac 2-Hour Power
Do you have an emergency preparedness kit for when your power goes out for an extended period of time? Do you like to go hiking or camping and find yourself off the grid long enough for your mobile phone to have a dead battery? In both cases, you can't recharge your phone once its battery dies down. I recently had lunch with a coworker and his solution was to carry around a spare battery. At some point though, you're still going to run out of power if you can't recharge.

Rayovac offers two solutions for this, one of which I got to play with. There is their 2-Hour Power product which allows you to partially charge your phone from a Rayovac Lithium CR123a battery and a 7-Hour Power version which works off of 4 AA batteries to give you a full charge. I got to play with the 2-Hour version.
Rayovac 2-Hour Power Components

The 2-Hour Power is extremely lightweight (30g/1.1oz) and easily fits into a backpack or emergency kit. There are two versions of this product, one that plugs into a Micro USB port, the other for an iPhone4/iPod. The 7-Hour Power product doesn't connect directly to the device. Instead, you can connect any USB-based product to it.

With either product, just connect to your device, turn the battery-based charger on, wait for the phone to charge, and your ready again to use. The benefit of the 2-Hour Power is size, the 7-Hour Power benefit is the more standard connector. Timing for both is based off Samsung Galaxy SII needs.

The box claims you can throw the device in the closet/drawer and not use it for 10 years and it will still recharge your device. This was the first issue I had. The phone connectors are apt not to be the same in 5 years let alone 10. One of them is even outdated already as the iPhone 5 uses a different connector. The second issue I had with 2 Hour Power is the Lithium CR123a battery. You're apt not to have extras around, unlike the AAs used by the 7-Hour version. The 2-Hour Power pack rules on space though, so if you want a short-term solution for extra power when hiking/camping, this is a great low-cost/low-space solution at just $20.

The 7-Hour Power seems the better option of the two, though. First, it runs off of AA batteries. Alkaline, but still standard AA batteries. I have enough of those around that I could recharge the phone many times over if power were out for an extended time. The AA batteries cost less, too. More importantly though, the 7-House Power product allows you to plug in any USB-based device. That connector is a bit more standard then the ever changing connectors found on phones, so is more apt to matter in 10 years. It is a little bigger though, but you get a full phone charge off those batteries. Of course the device is bigger, so if you're space conscious, and the shorter amount of talk time is fine, stick with the 2 Hour version. 

Here's a quick video to show you how they work.

  6. Thanks for this review. I have not seen these chargers but I will look for them. I think the 7-hour charger would be great for my emergency supplies. The 7-hour charger would be great for those times when our power goes out in the winter time.

  7. When you first get the 2 hour charger do you have to charge the unit first and if so do you have the charger off or on to charge the battery pack

    1. There is no plug for the two hour charger. There is a battery. The phone charges off the battery. Charge the phone, kill the battery. Get a new battery for next time.
