IN SHORT
- Same plug doesn't mean compatible.
- Use the charger specified for that pack.
- Don't use a damaged or wet charger.
A CHAT WE SEE A LOT

Rider
two chargers on the kopitiam table
which one for my pack? 😬
kopitiam court damn fast one 😂
aunties and uncles already appeal the connector sia
before anyone even checks what the pack says 👀
same plug can use already? 🤔
same plug doesn’t mean compatible lah
use the charger specified for your pack
ask the maker if unsure
Plug fits. That proves what?
The plug went in and the whole kopitiam is ready to close the case.
All that tells you is that the connector fits the socket. It doesn’t tell you the charger is the one specified for that pack. “Can plug in” sounds like a full answer because the plug is the part you can see. The electrical question is still open.
A connector’s nickname doesn’t settle it either. From the outside you can’t tell the connector standard or how it’s wired. If the maker’s documentation is missing, ask the maker or an authorised service provider before you charge.
Same look, different label
Read the charger’s label next to the battery’s label. These two chargers look alike. The model and the output voltage printed on them are not the same.
Three checks before you plug in
Start from the charger the maker specified for the pack. These checks help you recognise it. They’re not a way to pick a replacement. Not sure what the V and A on the labels mean? Reading the label: V, Ah, A and the cell model explains them.
- Output voltage: match the battery’s charging requirement.
- Charging current: check what the battery is designed to accept.
- Connector and polarity: appearance alone doesn’t tell us how the connector is wired.
SAFETY Mark also got limits
Singapore’s Consumer Product Safety Office advises using the manufacturer’s recommended charger and checking that the AC adaptor has a valid SAFETY Mark. The mark doesn’t tell you whether a particular charger suits your battery.
What to send us
Not sure about a charger? Send the battery label, the charger label, the charger’s output connector and the battery’s charge port, plus any adapter in between. Photograph them as they are: don’t open either one and keep the wiring as it is. Tell us which pack the charger came with.
A photo of only the connector, or a listing that says “charger included”, leaves the main question open: is this the charger specified for this pack?
Same plug, different story.
What now
Kopitiam court can close the case only after the maker’s answer, not after the plug goes in.
Use the specified charger
Use the charger specified for that pack.
