Survival Frog EasyPower USB AA Rechargeable Batteries -1.2V/1450 mAh Long Lasting Double A USB Co. - (4 Pack)

TLDR: Great product. Solid made, easy recharge, charge held well. 98% comparable to capacity of a regular AA Duracell battery. One out of four batteries was damaged for me, and before I knew for sure, the seller already sent me a new pack. I am definitely coming back to purchase again from this seller. Long story for whose needing more details... and nerds. =3 I use a high-powered device every day for work and hobby. I've started with a NiMH rechargables, but within a few months they were inoperable, due to constant abuse (also low quality, but I got them with the device). So I decided to try the regular AA Duracell and Energizer batteries. Both are NiCa and rated around 1400-1700 mAh. I clocked about 7 hours of use off the regular batteries, give or take half hour. Getting tired of spending money constantly on batteries and polluting, I look up these batteries. Now, I've also looked around - amount of mAh, reviews, even company itself. I decided to try out Survival Frog. I was not disappointed. As I have mentioned above, I think one of the batteries is a little degraded chemical-side and discharges quicker than its partner in my device. So this kept in mind I would like to speak mostly about the good (regular) pair (there are four in the pack) and provide best/average stats as I have came to experience them. First of all, the items are great in terms of use - they compare to the regular batteries within 98% of capacity, in my opinion (about 10 uses for me at the time of writing this review). For the remaining 2%, they made up more than enough with rechargability. So some of my testing/usability stats: - With my high-power device I get a solid 6-7 hours of time, solid use, no issue, no interruptions. (compared to 7 hours of Duracell) - I have charged with a Mac, "PC" and car charger. Different amp grades. Consistent use, Batteries shut off on their own. - Recharge time is about 40 minus off a computer-out USB (I have not clocked car charging because driving take attention, sorry) Pros: - Reusable over and over... and over... No drop in performance after 10 charges, consistent use time. - Rechargeable (I mean... this is why you are buying them... So you already knew this. =)) - "Comfortable" - Cap is secured well for the USB connector, although I will need to see how long the rubber string lasts. Looks decent though. - Comes with a small USB hub for charging. Very lightweight with switches for on-off. - Very lightweight (I think they are lighter than regular batteries) - Design is, actually, pretty nifty (Minus the color, but is for "frog" color) - Seems to be build quite solid - don't seem flimsy Cons: - Caps don't always fit well visually, but only visually - there is no interruption in service and electric contact is solid - Poison-Green color is a con for me, per personal preference. I would definitely purchase again, when the charge degrade.

These are great to use in place of your regular batteries! Instead of throwing away batteries after their power is used up, these batteries you just charge and use over and over again! Fantastic!

These are great for your money, But are they really worth the extra money? Im asking this question because you can buy normal rechargeable for around the same price if not cheaper with a charger. If your someone that travels a lot and you have a laptop and portable charger then yes these are great, But for the most part it would be cheaper just to get the normal non USB or Micro-USB AA/AAA/9V/D. The life is around the same. If you want to buy these because of the look and the function then buy all means do so. I bought them because I have both USB and normal US outlets. The build quality feels great and does imitate the feeling of normal AAs and does go green when fully charged. I can use a Xbox controller for around 3-4 days and my daughter can play with her toys for a full day. These are a good buy even if you want something to fit that modern life style.

I've been using these for years & they WORK & are super convenient. I have saved a ton of money on batteries for everyday things like my xbox controller, electric toothbrush, wireless mouse, etc. And it is so convenient when your wireless mouse battery dies & you can just charge the battery right into the USB port of your computer. I have had only 1 battery in my briefcase since I've discovered this item - and I have yet to throw out a single battery. They haven't gone bad yet & it's been years! As long as they continue to make it, me & my family will continue to buy it. I only wish they'd ship to Hawaii, otherwise this is an amazing value.

Some of the other reviews made it sound like I would need to be charging these pretty regularly, but the one I've been using in my computer mouse, I've had in there for almost 2 months and the one battery has lasted this whole time without swapping it out. They fit perfectly, so there is no worries about them being the wrong size or anything with the cap. It makes sense that the cap would be attached, that you cannot fully remove it just to make sure it lines up correctly when you put it back on, and having that cap attached limits where I can charge it, I use a USB hub, so I had to move some wires to get it to fit, but they charge very quickly, and they definitely hold that charge. I wish I had these when I was younger, and needed more batteries in my life. I would have saved a lot of money.

I had bought a set of these a while back from a different company ( although the batteries look identical). I lost one of the four original batteries, so I decided to order these. Of the four , one won't take acharge, blueled doesn't light up ble at end of charge, it just goes off. It doesn't show a charge on my battery tester or multimeter. The other three seem OK, though.Will be hesitant to buy again

This package is a dream! The included charger even has attractive LED lights (Red for Low, Blue for Charged). The four batteries were already fully charged when they reached me, and I haven't yet had to recharge them, so I can't tell you how fast or effectively the charger actually works — but they power my shaver beautifully, and I look forward to my next trip! I'll leave this lovely little charger at home and use my phone charger to charge these batteries (one at a time) if they should happen to need it, saving packing space. But, for home use, the four-port charger will be ideal.

Love these batteries they are easy to use recharge with the USB or pass through charge with a charging base they also change color when usb charging from red to blue great little batteries One thing wish was better is the cap it is held on with a plastic cord witch is very short would like to see it longer makes it hard to charge in some instances

Got these for my Oculus Rift S, use two while the other two are charging. So far I'm very happy with them. Nice build quality, come with a case to keep them safe. A good purchase for sure

bought to use in my tv remote as it eats duracells, these don't last as long but cost a whole lot less than duracells to replace. should break even in about a year

So sensible. No endless hunting for a charger. Just a battery you can re-charge so easily Best innovative idea I’ve seen in a long time.

I use these batteries only for my Logitech G604 wireless mouse. It's been about a year (Maybe 9 months?) and they're fantastic to have. Pop the top, plug it into your computer to charge, take another charged battery and put it in, and you're off to the races. The mouse typically lasts about a month and a half, maybe two on a single battery charge. Regular AA batteries spit power out at 1.5v while these batteries spit out 1.3v. But my mouse hasn't had a single issue with these batteries. I was concerned about this issue when i made the purchase, but, I've not had a single problem.

اشتريتها من فتره موش قصيره ... بس انا قولت ادى تقييم متاخر تكون خدت حقها فى التجربه هى جميله جدا و فكرة انها تعاد شحنها عن طريق منفذ يو أس بى دى فكره جديده و موفره لشراء بطاريات اما عن الشحن هى بتشحن فى مده قصيره و دى ميزه حلوه اما عن فترة الاستخدام هى موش بتطول و تقعد كتير مقارنة بالانيرجايزر .... بس حلوه جدا فى المجمل و على قد فلوسها... و مؤديه للغرض و منقذه للمواقف طبعا
