4 Pack USB Rechargeable AA Batteries with 4 in 1 Charging Cable, 1.5V Lithium Double A Size Battery 1200mAh for Blink Camera Xbox

The ONLY rechargeable batteries I’ve ever bought that work with all my items, including the ones like Blink cameras or WiFi water meters that claim they can’t take rechargeable batteries. So far, have had them in my Blink cameras for about 3.5 months and battery level still showing strong. Will be buying more

A un no lo pruebo pero llego a tiempo y completo apenas lo estoy cargando gracias

Nice batteries for ham or security cams that drain a lot of batteries. Amp hour could be higher.

Nice rechargeable battery with charging cables.

One of the best AA that have a USB port built in.

Nothing complicated to charge. Thry last long and charge fast. Great for trailcams and deer feeders in cold weather

I love howLong the battery last long, easy to charge too

I'm all-in on *rechargeable* AA batteries. Save time, money, recycling hassles.With a built-in USB-C port, these are even less hassle, and less likely be mistakenly thrown out. Less likely to be mistakenly put in the wrong kind of charger.These have less capacity than most throw-away AA batteries (Alkaline and Lithium), and less than some competing Lithium rechargeables.Note that for 1.5 volt batteries, 1 mAh (milli-Amp hour) equals 1.5 mWh (milli-Watt hours).PROs:- Status light shows when charging is working/done.- No special charger needed, just a USB-C cable with USB-A or USB-C power supply.- Nice price when $2.50 per batteryOKs:- They work fine- 1200 mAh capacity is less than HenreePOW brand and some others- Charges from included 4x cable, or any USB charger, including PD charger- They play nice with my flashlight's low-brightness mode (see Note 2)- Included 4x charging cable is very handy- Nice plastic case included- "Self-discharge" rate is not stated (see Note 3)- Voltage converter maintains voltage (hard to know charge status). (See Note 4)CONs:- Unbranded product (see Note 1)- Less capacity than some competitors- - - Alternatives - - -Lots of competitors on amazon, including exactly the same unbranded batteries @ $10-12 per 4-pack. I also tried HenreePOW brand, which claims 21% more capacity (1460mAh).- - - Notes - - -Note 1: Branding and model info indicates ongoing reputation management. It eases followup in case of problems. It helps you know that all reviewers are talking about the exact same product.Note 2: Another brand I tried (from Fitinoch) caused some flickering when my flashlight was on reduced brightness. These do not.Note 3: Self-discharge...How quickly do they drain when sitting idle? Often stated as Percent per year. If they self-drain significantly, they are much less useful.Note 4: When you try to measure the voltage with a volt-meter, the reading jumps all aver the place. Probably the battery's voltage regulator doing its thing. When these batteries are getting low in my smart lock, the battery status % indicator will probably not know. It reads battery voltage to determine status, and these maintain constant voltage even when nearly drained.
