UpBright AC/DC Adapter for ALLPOWERS AP S300 - Reliable 60W Charger

In this review the focus is on the UpBright AC/DC Adapter compatible with the ALLPOWERS AP Model S300 portable power station. The bottom line: this is a straightforward replacement charger for owners of the 288Wh, 300W (peak 500W) battery unit who need a tested, working power supply that supports worldwide mains voltages. The reviewer found the adapter useful for travel and emergency backup because it delivers the rated DC20V 3A output, includes standard safety protections, and comes with reasonable support terms from UpBright.

Key Features

• Wide input range: The 100-240VAC 50/60Hz compatibility lets users charge the power station across different countries without a voltage converter.
• Correct output rating: The DC20V 3A (60W) output matches the power station's expected charging input so charging is steady and reliable when used as intended.
• Built-in protections: OVP, OCP and SCP protections provide peace of mind against over voltage, over current and short circuit events while charging.
• Tested units: Units are reported as tested and in great working condition, reducing the chance of receiving a faulty replacement adapter.
• Manufacturer support: UpBright backs the adapter with a 30-day refund window and 24 months exchange coverage, which is reassuring for replacement parts.

Who It's For

This adapter is for owners of the ALLPOWERS AP S300 style 288Wh portable power station who need a direct replacement or spare AC/DC charger that supports global mains voltages. It also suits users who frequently travel or camp internationally and want a charger that will work on 100-240VAC without additional converters.

It is not aimed at people who need faster charging than 60W, those requiring an OEM-branded factory adapter for warranty purposes, or owners of power stations with different input voltages and connector types. Buyers should confirm their unit expects a 20V DC supply before purchasing.

Pros & Cons

Pros

• Compatible 20V 3A output provides steady, appropriate charging for the 300W portable generator.
• Worldwide 100-240VAC input removes the need for a separate voltage converter when traveling.

• 30-day refund and 24-month exchange policy give buyer confidence in the purchase.

Cons

• Maximum 60W charge rate can be modest compared with faster chargers some users might prefer.
