RPNB Portable Car Gun Safe Review: Budget Keypad Box, Worth It?
The RPNB Portable Car Gun Safe is a slim, low-cost steel box for one small handgun, with a backlit keypad, two backup keys and an included mounting kit and security cable. It fits a buyer who wants an inexpensive vehicle or desk-drawer lockbox and is willing to read the listing closely for the details it leaves out. It is a weaker fit if you need a stated interior size, fire protection, or a heavy gauge steel box you can verify, because those numbers are not in the information we reviewed. This review is based on the Amazon listing, seller bullets and description, not on ownership or testing.
Bottom line:
- Best for: a budget car or drawer box for one compact pistol, with keypad speed and key backup.
- Main strengths: USB-C emergency power port, mute mode, memory foam lining, included cable and mounting hardware.
- Main trade-offs: no interior dimensions or steel gauge on the listing, unclear battery type, and a very slim profile that limits fit.

Access and lock
The main way in is an electronic keypad. The seller says the backlit keypad accepts a personal passcode of 3 to 8 digits, which is a wider range than many low-cost boxes offer. Longer codes are harder to guess, but a code that you cannot recall under stress is a liability, so pick something memorable that is not a birthday or an address. The listing also describes automatic door opening after a correct code and a mute mode for quiet use, which matters in a bedroom or a parked car at night.
Two manual backup keys come in the box. Store one of them away from the safe itself, for example in a separate secured location at home, and never leave a key in the vehicle with the box. Keys are the answer if the electronics stop responding, so treat them as part of the safe, not as an afterthought.
There is also a button tool in the package. The listing excerpt does not say what it is used for, but a tool of this kind is commonly used for programming or reset steps, so read the manual before you set a code and keep the tool somewhere you will find it later.

Build and security features
The seller calls the construction sturdy steel with a corrosion-resistant black finish and lists the material as alloy steel. No gauge is given in the information we reviewed, so we cannot say how thick the walls or lid are. Be cautious about assuming that a slim box at this price level resists prying the way a heavier unit does. Treat it as a deterrent that keeps a handgun from casual access by children, passengers or a quick-glance thief, not as burglar-grade protection.
The anti-theft angle rests on the mounting kit and the security cable. A cable ties the box to a seat frame or a fixed object, and the kit lets you fasten the unit to a surface. Fastening a box to thin sheet metal or to a plastic panel only helps if the anchor itself is strong. See our walkthrough on anchoring a safe in our best portable gun safes roundup, where the cable and anchoring ideas apply here too.
The high-density memory foam lining is described as protecting the firearm and valuables from scratches and dents. It also tells you the usable space is a little smaller than the shell. The listing does not state a fire rating, a water rating or any third-party certification, so do not assume any.
Interior and fit
This is the part to research the most. The outside measures about 11 inches deep, 7 inches wide and just under 2 inches tall, and the listing excerpt does not give inside numbers. After subtracting wall thickness and foam, the usable height may be well under an inch and a half. That suits slim, compact pistols and may rule out anything with a tall grip magazine, a mounted light or an optic. Check the product gallery for a photo that shows a gun in the box, and measure your handgun at its thickest and tallest points.
The listing calls this a small handgun safe, and the title says small pistol. Pick it only if your pistol is small. For bigger frames, the best small gun safes guide lists boxes with more room, and the broader best car gun safes page compares vehicle-friendly options. Small valuables such as a passport or spare keys will fit only if they are flat.
Mounting and placement
The spec table lists floor mount and the box ships with a hardware mounting kit and a security cable. That gives you two ways to secure it: screw it down or loop the cable. In a vehicle, many owners route the cable around a seat bracket and keep the box under the seat. In the home, a drawer or the floor of a closet works.
Whatever place you choose, think about temperature. Electronics and batteries can behave badly in a car left in a heat wave or a deep freeze. Laws on child access prevention and storage vary by state, and transporting a firearm in a vehicle is regulated differently from place to place, so check yours before you decide how and where to keep it. Never drill into a vehicle structure unless you know what is behind the panel.
Power and batteries
The seller does not name the battery type or quantity in the part of the listing we reviewed, so confirm that before you buy and keep spare batteries on hand. The standout power feature is the USB Type-C port on the side. The seller says it provides an emergency way in when the batteries are dead or the backup keys are missing, but it is intended for emergency use only and not for long-term charging. A charging cable is not included, so buy a Type-C cable and keep it with your power bank.
That gives you three layers: keypad, keys and emergency USB power. Set a reminder to replace batteries on a regular schedule rather than waiting for a low-power warning.
What owners say
No owner feedback summary or topic list was included in the data for this model, so we will not describe what owners report. The listing is described as moderately reviewed. In the Amazon comments, search for the things that matter at this price: whether the keypad is responsive, how quiet the mute mode is, whether the interior fits a specific pistol, and how the seller handles replacement parts under its after-sales promise.
Look for repeated, specific points and discount one-off comments. The RPNB Portable Car Gun Safe listing on Amazon shows the newest feedback.

- Light at 3.9 pounds and very slim.

How it compares
The Hornady RAPiD Safe Night Guard is a nightstand-style RFID box with a clock and USB charging points, built with 14 gauge steel per the seller. It costs more but is far better as a bedside fixture.
The RPNB RP311F is a vertical fingerprint safe that mounts under a desk or counter, and is a sibling in the same brand family. It is the better choice if you want biometrics and a fixed spot.
The BILLCONCH Biometric Handgun Safe adds fingerprint, PIN, app and key entry and room for one large or two standard handguns. It is a bigger, fancier box.
The ONNAIS Iron Pro combines fingerprint and keypad entry with a wall mount and USB-C emergency power. It suits a fixed location rather than a vehicle.

Final verdict
The RPNB Portable Car Gun Safe offers a lot of backup options for a very low price: keypad, keys and USB-C emergency power, with a cable and mounting kit in the box. The unknowns are what hold it back, namely interior size, steel thickness and battery type. Buy it for a small pistol in a car or drawer once you have confirmed fit from the listing photos, keep your expectations modest on pry resistance, and always verify the current price and details on Amazon.
