POWEROWL 8 Pcs 2800mAh AA Rechargeable Batteries with 8 Slot Battery Charger, USB Fast Charging, Input DC 5V 2A, Output 1.4V 250mA, Independent Slot

Review: Powerowl AA & AAA Rechargeable Batteries with ChargerThe Powerowl rechargeable battery set is an excellent value for anyone looking to reduce waste and save money. The AA (2800mAh) and AAA (1000mAh) batteries hold a good charge, even in high-drain devices, and offer up to 1200 recharge cycles.The 8-slot USB charger is convenient, allowing independent charging for both AA and AAA batteries. Charging is reasonably fast (3-4 hours for AAs), and LED indicators make it user-friendly. While it’s compact, a travel case would have been a nice addition.Pros: High capacity, eco-friendly, flexible charging slots.Cons: Charging speed could be faster; no travel case.

This is a compact battery charger for AA and AAA and works well letting you charge both sizes at the same time and can do up to 8 batteries at once.So does exactly what you want from a charger

The charger is pretty cool - and seems to work ok.The instructions are a little ambiguous - i think it tries to say that you should try and keep batteries together so that if you put say 3 batteries in a device, then you should try and recharge them all at the same time and then put them back into a device together - e.g. don't keep recharging the batteries and swapping them about since you'll have mis-matched 'aged' batteries. It also says don't leave the batteries in the charger - which is a shame since it would've been great to have them stored in one place and always charged ready to go.I found that the first time I used some batteries (in a cat flap) after a week or two they were going strong (cat flap showing green) and then dead very quickly (cat flap dead when usually it would give a red warning light for a day before dying). Instructions say that it'll take a few charges before batteries are up to strength and I think it's true for the AA's - they now seem to be working well after a few charges. However with AAA's I keep finding that for a IR night light with 3 batteries, the power drops quickly a day to two after charging. Then when I charge the batteries, 1 battery charges really quickly while the others take a while. Another night light seems OK so possibly the odd battery is funny.Anyway I shall persevere and try fully discharging and then recharging naughty batteries to see if that gets em going ok.In summary though - although there are small niggles with battery management - I'm finding I'm saving way more money than if I was still buying non rechargeable batteries.

Works well for charging 8 batteries at once. I've used the rechargable batteries in handheld devices and wireless controllers for gaming. The battery life seems good but getting to full charge does take a while, and I've noticed there seems to be some kind of self-discharge when the batteries havent been in use. It still beats having to buy new batteries often though.

If you have triple A and double A rechargeable batteries then this great as you can do both at the same time. I’m using a 200W usb usbc hub system and helps charge the batteries quicker and is also available in Amazon for £35.99 that has 4 usb ports and 4 usbc ports. Worth the money in my view.

The POWEROWL Rechargeable AA Batteries are impressive with their 2800mAh capacity and low self-discharge feature. The 8-slot charger with USB fast charging is a convenient touch, allowing for independent charging of each battery.However, I encountered compatibility issues with certain Amazon batteries, which did not work well together. Despite this, the POWEROWL batteries perform well and offer reliable power for various devices. If you're looking for high-capacity rechargeable batteries and a versatile charger, these are a solid choice, just be mindful of potential compatibility concerns.

good product hold charge well

I had high hopes for these POWEROWL 8 Pcs 2800mAh AA rechargeable batteries, but unfortunately, they’ve been a huge letdown.First of all, the charging process is incredibly slow. Even though it claims to support “USB fast charging,” the batteries take forever to charge fully, and the charger doesn’t seem to be able to handle all the batteries at once efficiently. The charging speed is much slower than what I’ve experienced with other rechargeable battery brands.Secondly, the batteries don’t hold a charge well at all. After charging them, they barely last through a few hours of use. I tried using them in various devices, including a digital camera and a remote control, and they just don’t perform as expected. Even when they were new, the charge seemed to drain much faster than other rechargeable AA batteries I’ve used.Additionally, the independent charging slots might sound convenient, but they’re actually a hassle since it takes longer to charge each battery individually. I also noticed the charger doesn’t seem to provide any indication of when the batteries are fully charged unless you pay close attention.Overall, I’m very disappointed with these batteries and the charger. They’re nowhere near the quality I was expecting for the price. I would not recommend them to anyone looking for reliable and long-lasting rechargeable batteries.Save your money and go for a more reputable brand.
