Daweikala Aliexpress Anmeldelser 

There is no way these are 12800mWh batteries. They don't hold a charge as long as my 750 mWh.

Habe Litium 12V 15 AH Akku im Nov 2025 gekauft, 2 mal geladen, plötzlich komplett tot. Keine Spannung, keine Stromfluß, nicht mehr ladbar. Rekalmiert, werde nur hingehalten.

This company is selling fake Samsung batteries which are well below the stated capacity. Don’t use them they are substandard and definitely fake don’t waste your money on this firm. I have so you don’t have to completely fake every thing about them is fake internal resistance fake capacity fake absolute con men, be warned.

This seller does nothing but lie.
Item arrived in Australia on the 17th of August as stated by their tracking number.
1 month later they say that Australia Post has the package.
Checked with Australia Post and advised they don't have it.
Seller still adamant this is not true.
Lodged a complaint with Australia post and received a email stating that they have been given a tracking number but they don't have the package, Australia Post say to check with sender to follow up.
I have asked for a refund or replacement and to be sent by another reliable provider.
To date no reply typical, these people take your money and blame others for the delay.
I will read reviews in future and try not to be scammed again.

Impossiible to charge. I use a Liitokala Lii-4S charger which works well with other Li batteries. But my Daweikaka 12800 mWh (1) batteriers are dead. So they all end up in the battery waste container. The charger respomd to a 12800 mWh battery by raising the the loading charge to 3.74 V but the loading current remains 0.000mAh. Keep away from them.

Tested their 9V Li-Ion 5500mah battery at 65ma drain current & the battery lasted 4 hours which amounts to 260mah. The battery dropped to 0V immediately.
This advertised battery is a Fake !!! Don't get screwed by Daweikala. Scammers !!!

N.B. Testing data available

Absolutely fake LiFePO4 batteries, nowhere near the Ah they state. Will be extremely dangerous once the BMS starts to fail as it won't be able to balance the cells properly. Please don't buy from them, their items are very poor quality.

They are scammers, don't buy from them, they set very cheap prices to attract customers and give fake tracking numbers, luckily, AliExpress returns the money.

Regarding 8176725156728715 - the battery indicates "fully charged" at 36.3 V.
The company does not react to several complaints like this one here.
I can not recommend to buy from them!

Daweikala -C store are a FRAUD!
I ordered and paid rechargeable batteries on July 15. Now, three months later they say the batteries were delivered. NOT TRUE. First they said the batteries would be delivered September 23. NOT TRUE.
Do NOT BUY from DAWEIKALA -C store! They do NOT REFUND. They steal!

Ayant déjà passé quelques commandes qui se sont bien déroulées, je viens de me faire avoir en voulant acheter des piles 9V rechargeable en USB-C de 6800mAH de la marque DAWEIKALA.
Les piles sont bien arrivées, mais :
- la capacité réelle n'est que de 10% de la capacité annoncée, soit 500mAH -> durée de fonctionnement très limitée
- une pile sur 2 est tombée en panne juste après un an d'utilisation !
Moi qui pensait faire un achat intelligent et durable avec ces piles rechargeables...
Je pense qu'il ne faut acheter que des articles que l'on retrouve chez les détaillants français, et qui correspondent donc aux normes européennes...ce qui n'est pas le cas de ce type de piles !

Seller do not ship goods and hold your money as long as he can, refund takes long time, AVOID
