Thanks for posting these deals (almost daily?). My stack of flashlights and lanterns has grown somewhat. LMAO

Last night we had a power outage, and having a number of camping lanterns on the ready made it less of a challenge. Some of those posted in previous days/weeks were really good deals, as they came with nice 26650 cells which aren't cheap and last a long time even on "high".

Note that some of them do require batteries, some require multiple D-cells which should be obsolete in today's age of 18650 etc cells being widely available.

Nothing for me this round, although that wrap-around headlight does look tempting. Do not need it. Do not need it. Do not need it. Do not need it.
😀😃🙂 1100 lumen with 3 AAA !? Wow. "That's awesome !" (sarcastic ). Let's do the math: 3 batteries x.75A (an average of 750 mA) x1.5V=3.375 W. LED has 90 lm /W, so a maximum of 303.75 lm.

Like I've heard you're not supposed to keep a laptop plugged in all the time because it kills the battery even if you never use the battery.
Yeah that's why I said the longevity of the battery is not clear. I would think if the flashlight was designed to be plugged in all the time the battery should last, otherwise the reviews will show. For around $4 each, I'd be fine if they last a few years at least. I have a portable DAC (for audiophile headphones) that has an internal battery and doubles as a power bank that I've kept plugged in and charging all the time for years without issue. I am not familiar with the different rechargeable battery types, if anyone knows please chime in.

I picked up a 3-pack of the rechargeable plug-in flashlights last time precisely for power outages. The flashlight comes on automatically when power is cut. Not sure about the longevity of the rechargeable battery but I like the idea that in case of emergency to always know where a charged flashlight is and not have to scramble to find one or to discover it's low on battery.
Something else to tempt you if didn't pick these up already?
Ha, thanks, but power outages here aren't like life or death situations, so I don't need a constantly plugged in emergency light. With my stack of flashlights, easy to find a couple at different places.

Yeah, depends on the battery type. Rechargeable Li-Ion batteries don't like to be fully charged (or fully discharged) for extended times, so keeping them around 50-85% is probably optimal.

However, for cheapos like this I doubt they'd use Li-Ion batteries, most likely there are just a couple of NiMH batteries in there.

Two thoughts... 1) keeping something plugged in does not necessarily mean it (trickle) charges all the time. There may be a voltage drop detection which initiates a charging cycle and then turns charging off until the voltage drops below a set point. 2) It isn't in the sellers/manufacturers interest to maximize the life span... they would rather sell their wares repeatedly.

Example - those handheld Li-Ion vacuums, with their handy-dandy chargers, will die a rather quick death if you always return them to the charger after use. I have one for over 12 years already with still plenty of sucking power on the original set of 18650 batteries. It is only charged when it starts to slow down, and then removed from the charger.
They used to come with NiCd batteries which would die even quicker if not completely discharged because of their memory effect. That does not apply to Li-Ion, which just don't appreciate being fully charged all the time.

Whoops, that went way off topic.

Fun fact. The design of something like this to be rechargeable wastes more energy than using a typical AA.

No warranty on Energizer flashlights!

Yes, Constant charging of Li-ion will wear them out quickly. Li-ion flashlights and cells are available with negligible parasitic drain and will hold their charge for months. Experienced users do not charge them until the voltage drops to 3.0 -3.2 volts as indicated by a voltmeter built in to alternate low cost flashlights.

Is 50% off a slick deal?

Headlamps: The wrap around offers jogger safety and possibly light weight and comfort.
There is a lack of adequate specifications given on all of the flashlight offerings.

The Chinese manufacture the best budget flashlights in the world but you will not find these among any of Energizer's offerings. The 50% off in most cases is still above competitors every day price. It's a marketing ploy. The lumen claims are a farse. Each offering should be judged by its merits or lack thereof. Energizer's marketing model is built upon repeat buying of disposable items which in most cases end up in landfills poisoning aquifers or adding to the growing islands of floating trash in the oceans in less than a year.

Sealed disposable rechargeable: No voltmeter means the user will likely overcharge or undercharge. Brightness is lost quickly from day one.

Rechargeable with removable batteries: Energizer refuses to disclose any battery specs even when people ask. Cheap cold blue l.e.d. emitters are standard. Read the one star reviews. Switches fail within a few months. These are still disposable made with the lowest quality components. The short life will quickly cost the user more than if they purchased a quality budget flashlight for $25 to begin with.

Alternatives: I just purchased several Wurkkos TS models for gifts on sale at Amazon for $24. With power bank function $30. I do not recommend TS for most but I enjoy the wide range of tints, useful modes from turbo to flickering candlelight to bike flasher. Vonverts in size instantly from longer tactical with a powerful 21700 battery to a subcompact with a short battery and barrel. One button press direct access to modes with memory for last used mode and brightness. No need to switch through unwanted modes such as strobe. Press and hold to dim to achieve the required light level is state of the art and widely available in 2022.

For $20 on sale or with a coupon the Wurkos FC11 with simple U.I. offers a choice of tints in Samsung high CRI emitters has many of the above features. Sofirn Sc31 Pro is more advanced but the same price range. For friends whom I do not trust to safely handle loose 18650 cells I locktight the barrel and battery end cap and tell them to return it to me for battery replacement in three years. An excellent bare bones 18650 costs as little as $10.

FYI the blue 2 pack Eveready headlamps for $5.xx is back. I didn't check if the black rechargeable ones 50% coupon also came back or not (once you place an order, the coupon goes away for the blue ones). See this thread:
https://slickdeals.net/f/15783598-energizer-rechargeable-headlamps-2-pack-8-47-at-amazon?v=1

Btw, Energizer is owned by Eveready (or the other way around), in case anyone is wondering.
I bought the black (rechargeable) set last time and they are farking BRIGHT. (good thing)

.
Aren't some of the flashlights constant charges?
Like you keep it plugged in the docking/charging station all the time ?
