Best Portable Charger for BYD in Thailand: 3.5kW or 7kW?

A portable EV charger can be one of the most useful accessories for a BYD owner in Thailand.

Unlike a fixed wallbox, you can take a portable BYD charger when traveling, visiting family, or staying at another property.

But should you choose 3.5kW or 7kW?

Choose 3.5kW If You Want Simplicity and Flexibility

A 3.5kW portable charger is a good choice if you:

√ Drive short or moderate distances
√ Usually charge overnight
√ Rent your home
√ Have limited electrical capacity
√ Travel frequently
√ Want a backup charging solution

The lower charging power also makes it easier to use in locations with limited available electrical capacity, although the socket and circuit must still be suitable.

Choose 7kW If You Need Faster Charging

A 7kW portable charger is better if you:

√ Drive longer distances
√ Want shorter charging times
√ Have suitable electrical capacity
√ Own a BYD that supports up to around 7kW AC charging
√ Want portable charging instead of a fixed wallbox

For example, the current Thailand specifications for the BYD Dolphin and ATTO 3 list 7kW Type 2 AC charging, making 7kW an appropriate power level to consider for these vehicles.

Why Is Portability Useful in Thailand?

Thailand has a growing public charging network. PEA VOLTA, for example, operates charging stations across major routes and offers both AC Type 2 and DC charging options.

However, public charging is not always the most convenient option.

A portable charger can be useful when:

√ Your destination has no EV charger
√ You stay at a private house
√ You travel to another province
√ You want an emergency backup
√ You don't want to wait at a public charging station

This is especially relevant for drivers who regularly take their BYD back to their hometown.
