Was very pleased with the outcome of my test of this product. I have a Droid phone and was able to basically get two charges with the first set of batteries. I purchased this product to take to the Boy Scout National Jamboree where charging cell phones will be an issue. With this product I will not need to stand in line at a charging station. The USB cord is included which means that I only have to provide the extra batteries. Once the Jamboree is over I can keep this charger with me to use for emergency charges.

This chager and all the other AA battery type chargers will destroy your cellphone battery. Apparently, the chip inside your cellphone battery will get fried the 1st time you use one of these AA battery charger and your battery will discharge at a rediculous rate once it is disconnected. I have two of these battery chargers and thought it was a great idea. i used to get 8 hours out of my battery fully charged, now, I'l be lucky if I get 1 hour from it after a full charge. Once your battery is ruined, it's ruined for good. They should ddefinitly stop selling these kinds of chargers and somebody really do need to do an investigative piece on why they are being sold because it does they do destroy your cellphone batteries. AA batteries are incompatible with the batteries that are in you phone.

Great in a pinch

By JimK

Comments about Rayovac Backup Charger (PS73-4BT6):

Bought one of these during a recent vacation in Disney World. It was hard to go a full day without losing battery power, especially with a group of people, but this handy power pack charged cameras and phones throughout the trip. Especially convenient is that the unit itself doesn't need to be charged; it was much easier to find AA batteries than to find an outlet, and we didn't have to lose time waiting for a charge.

Comments about Rayovac Backup Charger (PS73-4BT6):

I don't need this everyday, but I have needed it a few times now to keep me charged until I get to my charger. It works better than I expected. I can get a full charge and really never have to worry about running out of power. Great for when I am on the road.

I packed the 7 hour charger for a road trip with my four sons. When their tablets died I plugged in the charger and it worked as advertised. Thank you for saving my trip. I have already purchased several more.

Item not usable for purpose advertised. A waste of money.

By Summer505

Comments about Rayovac Backup Charger (PS73-4BT6):

I am very disappointed with this item. I can not tell if it is done charging or even when it starts charging, I can not charge my android at all, and it takes forever to charge my iphone. This was truly money wasted. I would never recommend this item to anyone.

An effective and simple design

By EdNC

from NC

Comments about Rayovac Backup Charger (PS73-4BT6):

If you're the type who plans for emergencies, this is the cell phone back-up power device for you. Most back-ups use special or rechargeable batteries. This power pack uses easy to find AA batteries. And if you need even more talk time, just pop in replacement batteries. You can't do that if you have a rechargeable, and your AC power is still out because of an ice storm. Well done!

Bought this hoping to use this as an emergency charger for to my phone on the road....Nope. Will not work with iPhone 5S. Thier description as a battery pack for iPhone should be "Some iPhones". Works fine for my kindle. That's the only reason I gave it 2 stars.

Does as advertised

By blkandwhtlion

from Syracuse, NY, USA

Comments about Rayovac Backup Charger (PS73-4BT6):

This is great. I use it for emergencies only at first, but now realize that it is really convenient anywhere. Since it takes batteries it really becomes cost effective with rechargeables. So long as the batteries are good, this will work fine. Not much can go wrong except physical abuse. The only draw back is I can't carry this on me 100% of the time as it is a bit too big for my jean pockets with the cord and all. It never leaves my car though.

HORRIBLE PRODUCT

By r2bees

from Dallas, TX, USA

Comments about Rayovac Backup Charger (PS73-4BT6):

this was a WASTE of my money. The first time I used this product i waited for an hour for my phone to charge and I checked it was still on the same percentage. I thought well maybe I have too many apps running. So I turned off my phone. An hour later still SAME percentage. It s true you get what you pay for. This is a USELESS RUBBISH PRODUCT. I'm taking it back for a REFUND!!

Nothing great about this at all.

By Melgallegos

from New Mexico, USA

Comments about Rayovac Backup Charger (PS73-4BT6):

This product did not work. I did not get to use it once. I put batteries in it and they died before I got to use it.Ridiculous to keep batteries in my purse loose just because this product runs down batteries if you keep them inside. I will not recommend this product. Batteries were also brand new and Rayovac. Figure that.

disappointed

By Jana

from SW, KY

Comments about Rayovac Backup Charger (PS73-4BT6):

Since upgrading my iPad to IOS7, I have found that the battery doesn't last as long. When a friend showed me her charger, I was thinking it would be the answer to my problem, when away from electric power source. Was very disappointed when I connected my iPad to the charger and it read "not charging". I then plugged it up to my Galaxy Note and it is charging, so there is nothing wrong with the charger itself. But, as noted by others, it will NOT charge an iPad.

Cool product will mention to customers.

By pianoman6954

from Taylor, MI, USA

Comments about Rayovac Backup Charger (PS73-4BT6):

I bought this to use with NiMh rechargeable batteries but was really more impressed with its performance with alkaline cells. It's clear this is a simple joule thief and a very efficient one as I was able to charge a 900mAh lithium ion and a 2200mAh from 3.92 to 4.1 at 1/4 C rate. This breaths new life into alkaline chemistry batteries because this although their discharge curve is flat, their less than stellar discharge rate and energy density the do offer better long term storage capability than most rechargeable chemistries. This devices cuttoff voltage is clearly very low making a large pack of AA's and this device a must have for emergencies. A word of warning to other users that because of its low operating voltage this isn't ideal for rechargeables unless you plan to keep good track of them because this device would likely still operate at below nominal voltage for most NiMh and Ni-Cad chemistries.

Doesn't work with rechargeable batteries.

By SlyDog

from Springfield, OR, USA

Comments about Rayovac Backup Charger (PS73-4BT6):

I'm glad to have a product that I can use to recharge my camera while on a backpacking trip, but I'm disappointed that rechargeable AA batteries will not work, likely because of their 1.2v output. There is no reason that this product couldn't be designed to function well using 5 rechargeable AA batteries. Then, i'd be really happy. It is a real disappointment that so many products ignore the common use of rechargeable batteries.

Big disappointment

By Janice18

from Marion, VA 24354, USA

Comments about Rayovac Backup Charger (PS73-4BT6):

I bought this today for my trip coming up. Decided to charge the batteries to try it out. The batteries were on the charger about an hour when I heard this hissing sound. Battery acid destroyed the charger, was all over my counter. So basically, not sure if this works or not. Went to return it and get another and of course they are out of stock
