EEMB AA Batteries 4 Pack AA Rechargeable Batteries Lithium Batteries AA 4 in 1 USB Type C Charging Cable Battery 1.5V 2600mWh for Blink Camera Flashlight

Does exactly what you'd expect. Never run out of batteries again. Really handy for things like battery powered fairy lights, cameras. Come in a really useful case, and the charging cable is excellent.

Even among all the Cheap Chinese Trash (TM) advertised on Amazon, this is even more trashy than most. We bought them to power a Blink doorbell camera, charged two of them fully up (poorly fitting connector, by the way) and installed them. They worked for a few hours in the afternoon, then the temperature fell to about 8C, and they died completely. Returned for a refund (on principle - at the price, hardly worth the trouble). Amazon used to be fairly good as a supplier some years ago, but it has been overrun by sellers of really poor quality products, and now is akin to eBay but more expensive.

Excellent piece of well made equipment that was well packaged, great price and delivered in good time.

They seem to be good but, they are dangerous. If they are not plug in a cheap 5V 1A charger, they can pull up to 2A each to charge!!! That is insane as they can get really hot. On the flip side, they charged in under an hour...

Why did you choose this product over others?: Good value for a 4 piece product. Ideal for multi battery repeated usage with charging lights.

Didn’t know these types existed but after going through packets and packets of ‘disposable batteries’ for xbox controllers I decided to see if I can find better quality chargeable ones. I came across these! Brilliant customer service. And Definitely value for money

Defective item straight out of the box. One of the batteries would not charge or work at all. The USB-C connection is extremely stiff and the ports are not aligned very well. They look and feel cheap. Advertised as being for Blink cameras however they can’t even power one (in standby) for 24 hours. The only return option is to wait in for Royal Mail to collect them which is not overly convenient for many people. Manufacturer support site is all in Chinese writing so completely illegible to an English person. Managed to find a support email/portal which says they will be in touch within 24hrs, however I’ve been completely ignored. They clearly make it too much hassle to bother returning. Minus 5 stars.

Bought these for a camera which eats AA batteries, being Lithium Ion they have a flatter dissipation curve, normal Alkaline batteries tend to perform well for the first say 20% of use then tail off, these don't so keep working until their last bit of charge. Adaptor to charge all four with one USB and flashing charging indicators are useful touches too.

They last forever lasted like 1 month in my quest controller before they died

Batterie di buona qualità ad un prezzo molto attraente. La batteria in sé è secondo me ottima, garantisce 1,5V durante tutta la durata, adeguata. Come tutte le batterie di questo tipo non ti avverte quando sibsta per scaricare. Un po' scadenti gli attacchi USB-C. Forse perché i fori nella batteria non sono precisi, si fa un po' do fatica ad innestare lo spinotto.

Rapide et efficace

Facile à charger, quand elles fonctionnent, j'explique j'ai chargé les 4 premières sans soucis, puis le lendemain j'essaye de charger 4 autres, mais voilà cela ne fonctionnais pas, je les ai donc charger une à une dans un chargeur spécial qui chage les piles lithium et sur les 4 que j'essayais de charger, une était defectueuse et empéchais de charger les autres. Donc quand les 4 sont bonnes, cela fonctionne "normalement" ! Piles utilisées dans des claviers et souris -> conforme !
