Ryobi has introduced its latest Tek4 series, a lineup of 4V Li-ion products that encompass a wide range of tools, from measurement devices to security equipment to portable backup power solutions. Each tool in this series shares the same rechargeable 4V power supply and boasts an industrial aesthetic, with dark gray exteriors accentuated by Ryobi’s signature green highlights. What sets these tools apart is their use of the Li-Ion 4V battery (AP4001), which offers over 200 recharge cycles, lasting significantly longer than standard alkaline batteries.
Exploring the Tek4 Range
We approached Ryobi to acquire the entire Tek4 range, allowing us to thoroughly test and evaluate each tool to uncover their unique capabilities and potential applications. With a diverse selection of tools, the Tek4 system is well-suited for a wide array of professionals, ranging from electricians and air mechanical installers to inspectors, agents, estimators, and more. While we provide an overview here, we also feature dedicated reviews for each tool:
- RP4200 Ryobi Tek4 8MP Digital Camera Review
- RP4010 Ryobi Tek4 Professional Laser Rangefinder Review
- RP4030 Ryobi Tek4 Professional Infrared Thermometer Review
- RP4530 Ryobi Tek4 Noise Canceling Headphones Review
- RP4300 Ryobi Tek4 Motion Sensing Alarm Review
- RP4020 Ryobi Tek4 Professional Digital Multimeter Review
- RP4000 Ryobi Tek4 Self-Leveling Vertical/Cross Laser Review

- RP4310 Ryobi Tek4 Digital Key Lock Box Review
- RP4400 Ryobi Tek4 High Intensity LED Flashlight Review
- RP4700 Ryobi Tek4 4V Standard Charger Review
Of the aforementioned tools, we found the 8MP camera, laser rangefinder, infrared thermometer, noise-canceling headset, self-leveling vertical/cross laser, digital key lock box, and LED flashlight to be particularly valuable. Remarkably, the laser rangefinder, self-leveling vertical/cross laser, and digital lock box stood out for their exceptional performance within their respective categories. Adding to their appeal, the inclusion of the 4V rechargeable batteries significantly enhances the overall value of these tools, especially for users who rely on multiple devices.
Uniqueness of the Tek4 System
What distinguishes the Tek4 series is the varying methods employed to secure the battery within each tool. While cameras, thermometers, headphones, USB power supplies, and flashlights possess removable threaded caps, the remaining tools implement different mechanisms. These include single-screw doors, double-screw hinged doors, and even hidden latches that allow the battery to slide into place inside the tool. Although the lack of uniformity may seem unusual, it has no bearing on the performance of the tools themselves.
The Drawback: RP4700 4V Standard Charger
The only downside we encountered with the Ryobi Tek4 system is the RP4700 4V Standard Charger. This charger is included with each battery-operated tool but falls short in terms of efficiency. While it is compact and convenient, it takes an astonishing five hours to fully recharge a depleted battery. In comparison, the longest charge time we have experienced with 12V and 18V tools is 60 minutes, with most 12V tools completing the charging process in approximately 30-40 minutes. Fortunately, Ryobi offers a dual-port fast charger, available separately for $35, which significantly reduces the charging time to just 36 minutes, aligning it with our expectations of lithium-ion technology. Users who rely on multiple Ryobi Tek4 tools should consider investing in this charger rather than relying on the one provided with the individual tools.
Warranty and Availability
The entire Tek4 line is backed by a 2-year limited warranty and is exclusively sold at The Home Depot.
In my opinion, Ryobi Tek4 series has revolutionized the market, attracting particular interest from professionals in the real estate, inspection, and estimating fields. The overall value offered by these tools is truly impressive. However, it’s worth noting that the 4V battery’s charging time is inexplicably long, taking up to 5 hours for a complete recharge, and even partial charges averaging around 2.5-3 hours. To fully appreciate the variety and remarkable features of these products, I encourage you to visit your local home improvement warehouse and discover the Ryobi Tek4 series for yourself.
