Pros / The paging feature lets you make announcements across all devices in your house.

Cons / The base lacks the handy LCD display that each of the handsets has.

 Verdict / The Panasonic KX-TGE433B may not lead the pack with its battery performance, but its other useful features make it well suited to a home or business environment.

The Panasonic KX-TGE433B is ideal for home or work. It offers a large phonebook, plenty of storage for voicemail, and all the interface features and design options that you’d expect from such an established brand.

This cordless home phone’s battery performance is average. The handsets take about seven hours to reach a full charge. What’s disappointing is that this lengthy charge time only gets you 12 hours of standby use. Individual handsets won’t last throughout an entire day if continuously in use. However, you can add up to six handsets and rotate through them while you wait for another to charge. Some phone systems allow for as many as 12 handsets, so consider the size of your home or office before purchasing.

If you live in an area prone to power outages, this phone is a solid choice, as its ability to rely on rechargeable backup batteries keeps you connected whether there’s power or not. A fully charged battery gives you up to 12 hours of talk time and up to eight hours of standby time.


Both the base and the handsets have clear speakerphones that sound great. The phone system would be perfect for a conference call in a boardroom or as a desk phone for several employees in an office setting. Likewise, you can use the system to broadcast a message across each handset throughout your house, like an intercom. And should you ever lose a handset or two, you can page them from the base and they’ll sound alarm notifying you of their location.

The KX-TGE433B’s handsets have large backlit white LCD displays that are easy to view. The interface is intuitive to navigate, and its large buttons add to the overall usability.

The one major downside to this cordless phone is its lack of an LCD display on the base. Many other phone system bases have a built-in LCD screen where you can navigate a menu to adjust general settings, listen to voicemails and access tons of other features. The KX-TGE433B limits itself in this aspect quite a bit.

Although not a common reason to by a phone, its baby monitor feature makes it an asset to any family with young kids. You can place a monitoring handset in your sleeping baby’s room, and if they cry, an alert is automatically sent to the base unit and any phone number you choose. Additionally, you can opt for the Key Detector feature, which attaches to your key ring. Should you ever lose your keys, you can activate the detector from any of your handsets and hear an alert if your keys are within 200 yards.

Interface Options

From any of the included handsets, you can access and edit the system’s phonebook entries and caller ID log. Its phonebook can store up to 100 entries, and it keeps a log of the 50 most recent calls. If you miss a call, the phone can record up to 17 minutes of voicemails, which is more than most of the other units in our comparison.

The talking caller ID function is a convenient bonus as it announces the name of any incoming callers, allowing you to know who is calling without leaving whatever you’re doing at the moment. You can also easily block unwanted numbers on the system and program in commonly used numbers to its speed dial function.

Help & Support

Panasonic backs this landline phone with a one-year warranty, which is standard for the industry. There is also a variety of help and support options. You can contact Panasonic’s technical support staff via live chat, though they do limit that to business hours during weekdays. Aside from that, Panasonic hosts a wealth of informational resources on its website, including an extensive frequently asked questions section.


This Panasonic cordless phone set has a lot to offer and works equally well in a home or business setting. Its large buttons, cleanly designed display and helpful auxiliary functions make it a solid choice. Though its battery performance is somewhat weak, the Panasonic KX-TGE433B’s simple interface and rich feature set make it one of the best options on the market.
