Key Features

• Compact 98mm x 98mm Footprint — The handheld portable size makes this charger incredibly convenient for RC enthusiasts who need to charge at home, at the field or on the move. Unlike bulkier charging stations, the EZ-4 fits easily into your RC bag or transport case without taking up valuable space.
• 50W 4.0 Amp Charge Rate — This power output is perfectly calibrated for small to medium capacity LiPo batteries commonly used in 1/10 and 1/8 scale RC cars, drones, helicopters and boats. The 4 Amp maximum charge rate ensures fast turnaround times without compromising battery lifespan or safety.
• 2-4S LiPo Compatible — The charger accepts 2S, 3S and 4S lithium polymer batteries, covering the vast majority of modern RC platforms including Traxxas, ARRMA, FTX, Losi and other leading RC car brands sold throughout the UK. This versatility means one charger can handle multiple battery configurations across different vehicles.
• Built-in Balance Charging — The integrated 400mA balance current automatically monitors and balances individual cells during the charge cycle, extending battery lifespan and improving performance. Balance charging is essential for maintaining the health of your LiPo packs and preventing cell damage.
• Four-Step LED Capacity Indicator — Clear visual feedback shows charge progress at 25%, 50%, 75% and 100%, giving you immediate status without any guesswork. The simple four-LED system is intuitive for everyone from complete beginners to experienced RC pilots.
• Fan-Assisted Aluminium Casing — The robust aluminium housing provides excellent thermal management and durability, whilst the internal cooling fan ensures efficient operation and keeps the charger running quietly during extended charging sessions. This engineering approach means the charger won't overheat even during back-to-back charging cycles.
• Mains Powered with UK Plug — The charger operates on 100-240V AC input, making it compatible with standard UK household electricity. It comes supplied with a properly fitted UK plug, so you can start charging immediately without purchasing additional cables or adapters.
• XH Balance Lead Connector — The standard XH balance connector is compatible with the vast majority of modern LiPo batteries, ensuring you can charge any 2-4S pack with standard balance leads. This universal standard means excellent compatibility across different brands and models.
• Simple and Easy Operation — There are no complex menus, no confusing settings and no learning curve. The Powerpal EZ-4 is designed to be intuitive from the moment you unpack it, making it ideal for new RC enthusiasts who don't want to struggle with complicated electronics.

Technical Performance

The Etronix Powerpal EZ-4 is engineered with premium materials and intelligent design principles that prioritise reliability and longevity. The durable aluminium casing provides structural integrity and excellent heat dissipation, ensuring the charger maintains optimal operating temperature even during extended use. The internal cooling fan operates efficiently and quietly, circulating air through the chassis to prevent thermal stress on the charging circuits. At just 278 grams in weight, the EZ-4 is genuinely portable without sacrificing build quality or performance. The 50W power output is delivered with precision through intelligent charging circuitry that maintains constant current and voltage throughout the charging process. The 400mA balance current actively monitors each cell in your LiPo pack, ensuring even charge distribution and preventing the cell imbalances that can reduce battery performance and lifespan. The four LED indicators provide real-time status feedback, eliminating any uncertainty about your battery's charge state. Whether you're charging a 2000mAh 2S pack, a 4000mAh 3S battery or a 5000mAh 4S pack, the EZ-4 delivers consistent, reliable performance. Charge times vary depending on battery capacity and the 4.0 Amp output — for example, a 4000mAh battery will charge in approximately one hour, whilst a 5000mAh pack requires roughly 1.5 hours. The fixed 4 Amp charge rate is ideal for standard RC applications but may not be suitable for very small batteries under 500mAh, where a dedicated micro charger would be preferable.

Frequently Asked Questions

• Will the Etronix Powerpal EZ-4 charge my specific LiPo battery? — The EZ-4 will charge any 2S, 3S or 4S LiPo battery that features a standard XH balance lead connector, which is the industry standard for most modern RC batteries. If your battery uses Traxxas ID connectors or other proprietary balance systems, this charger will not work with it. For batteries with only main power connectors (like Deans or XT60), you would need a charger with dedicated main connector charging, which the EZ-4 does not provide.
• How long does it take to charge different battery capacities? — Charging times depend on your battery's mAh capacity and the fixed 4.0 Amp output. A 4000mAh battery charges in approximately 1 hour, a 5000mAh pack takes around 1.5 hours, and a 3200mAh battery requires roughly 45-50 minutes. For very small batteries under 500mAh, the fixed 4 Amp charge rate may be too aggressive and could damage delicate pack construction.
• Is the Etronix Powerpal EZ-4 suitable for beginners? — Yes, absolutely. The EZ-4 is specifically designed with simplicity in mind, making it ideal for newcomers to the RC hobby. There are no complex programming menus, no confusing display screens and no unnecessary features to learn. Simply plug it in, connect your battery, and the charger handles the rest. The four LED indicators provide clear, intuitive feedback about your battery's charge status.
• Can I charge multiple batteries at the same time on this charger? — No, the Etronix Powerpal EZ-4 is a single-channel charger and can only charge one battery at a time. If you need to charge multiple packs simultaneously, you would require a multi-channel charger or multiple individual chargers.
• Does this charger work with my Traxxas batteries? — It depends on your specific Traxxas battery. If your Traxxas pack features a standard XH balance lead connector in addition to any main power connectors, then yes, the EZ-4 will charge it perfectly. However, Traxxas ID batteries with iD connectors require a dedicated Traxxas ID charger and will not work with the Powerpal EZ-4.
• What is the balance current and why does it matter? — The EZ-4 provides 400mA balance current, which continuously monitors and adjusts individual cell voltages during charging. This is crucial for maintaining battery health and extending lifespan. Without active balancing, cells can drift out of synchronisation, leading to reduced performance and potential damage. The 400mA balance current is adequate for standard RC charging applications.
• Can I use this charger outside the UK? — The Powerpal EZ-4 comes supplied with a UK plug, so it is designed for UK mains sockets only. However, the charger itself accepts 100-240V AC input, meaning it can be used internationally if you purchase an appropriate travel plug adapter for your destination country.
• Does the Powerpal EZ-4 have a storage charge mode? — No, this charger does not include a dedicated storage mode. For safe long-term battery storage, you should manually charge your LiPo packs to approximately 50% capacity using this charger, then disconnect them. A dedicated storage charger with programmable modes would be required for automated storage cycling.
• What makes the aluminium casing important? — The aluminium construction provides several key benefits: excellent thermal conductivity to dissipate heat generated during charging, durable structural integrity that resists impact and wear, and a professional appearance. Combined with the internal cooling fan, the aluminium casing ensures the charger maintains safe operating temperatures even during extended use or back-to-back charging cycles.
• Is the Powerpal EZ-4 suitable for RC cars, boats, drones and aircraft? — Yes, the EZ-4 is versatile across all RC categories including RC cars, RC boats, RC aircraft, RC helicopters and RC drones. The 2-4S LiPo compatibility covers the battery requirements for the vast majority of these platforms, making it an excellent single charger solution for multi-discipline RC enthusiasts.
