How To Charge Your Cell Phone With A Damaged USB Charging Port In Your Car
In How To Charge A Cell Phone With A Damaged Micro/Mini USB Charging Port, it was clearly demonstrated (watch the video ) how to charge a Cell Phone at home with three (3) different Universal Battery Chargers:
- Universal Battery Charger With LCD Display
- Universal Battery Charger With LED Display, and
- Universal Battery Travel Charger
Here is a side-by-side comparison of the three (3) Universal Battery Chargers used in that demonstration, and their respective specifications:

In this subsequent article, we are going to show you how to use the aforementioned Universal Battery Chargers to charge a Cell Phone with a damaged micro|mini USB Port in your car.
Tools Of The Trade
To charge the cell phone, the battery must be accessible and removable/swappable. Needless to say that the methodology outlined in this tutorial does not apply to cell phones with inaccessible batteries. To proceed, we need:
- Universal Battery Chargers (obviously)
- Functioning 12V DC Cigarette Lighter Socket
- Cell Phone Battery or Batteries (Li-ion, Li-Pol, NiCd, or NiMH)
- USB Cable – USB 2.0 Male-To-Male Cable
- Universal USB Car/Vehicle Charger, and
- Mini Power Inverter (Pure Sine Wave, preferably)
The Universal Battery Charger With LCD Display and the Universal Battery Charger With LED Display come each with an integrated USB Charging Port, into which can be inserted one end of the USB Cable to charge the battery; the Universal Battery Travel Charger, however, doesn’t. We’ll show how to circumvent that roadblock to charge the cell phone in your car. Hence the need for the Mini Power Inverter to convert the car’s DC power into AC power.
Charging The Battery With The Universal Battery Charger With LCD Display
Read the minimal instructions on the packaging box first. Then:
- Align the positive (+) and negative (-) pins of the Universal Battery Charger with the positive (+) and negative (-) metal contacts of the Battery. The Universal Battery Charger With LCD Display shows the level of charge of the battery when contact is made, in increments of 25%.
- Insert one end of the USB 2.0 Male-To-Male Cable into the Universal Battery Charger With LCD Display‘s USB Port, the other end into the Universal USB Car/Vehicle Charger‘s USB Port.
- Connect the Universal USB Car/Vehicle Charger into the Cigarette Lighter Socket.
- Turn on the car’s ignition switch. The Universal Battery Charger With LCD Display should start charging the battery. When the Battery is fully charged, unplug the Charger, remove the Battery, and put it back in the Cell Phone.
Power on the Cell Phone. The battery status icon should indicate a charged battery, if it doesn’t, power on/off, and start the phone until the battery’s level of charge is shown.
Charging The Battery With The Universal Battery Charger With LED Display
Read the token instructions on the box first. Then, to recharge the battery:
- Repeat the above steps to get a similar outcome. The difference between the Universal Battery Charger With LED Display and the Universal Battery Charger With LCD Display lies not only in the specs (see above table) and the design, but also in the Display (the manner in which a battery’s state of charge is displayed). The former is color-coded (red, green, and blue – battery is fully charged), the ladder digitized (25%, 50%, 75%, and 100%).
Extended cell phone battery charging (ignition key in accessory position) with either Universal Battery Charger via Mini Power Inverter may deplete the car battery. Start the car, from time to time, to recharge the car battery.
Charging The Battery With The Universal Battery Travel Charger
Caution: do not plug the Universal Battery Travel Charger into any power outlet before installing the battery correctly.
Charging the battery with the Universal Battery Travel Charger in your car could have been as easy as following the processes outlined in the foregoing paragraphs, were it not for the lack of a USB Port; but since it is a different animal, some special considerations must be made to accommodate it.
The absence of a featured DC USB Port makes it almost impossible to use the Universal Battery Travel Charger to charge a cell phone battery in a car. Fortunately, thanks to a portable 70W-150W Mini Power Inverter, which converts DC to AC, this shortcoming is easily overcome. The best Mini Power Inverter, in our view, is a Pure Sine Wave Inverter, which produces AC household current.
Seriously, the best Power Inverters we recommend for that purpose are:
We love the first two Mini Power Inverters (modified waveform) for two (2) reasons: extra DC socket and versatile USB power port; the third one (pure waveform) for three (3) reasons: extra power (200W, 2 AC power outlets), versatile USB power port, and pure sine wave for sensitive electronics.
When the Universal Battery Travel Charger is connected into the Mini Power Inverter‘s AC outlet, it may render the extra DC socket and the versatile USB power port inaccessible. A workaround is to plug a Surge Protector with multiple AC outlets into the Mini Power Inverter‘s AC outlet, and then connect the Universal Battery Travel Charger into one of the Surge Protector‘s AC outlet (switch off). Don’t forget to turn on the Surge Protector to power the Charger.
To charge the battery, using the Universal Battery Travel Charger and a Mini Power Inverter, proceed as outlined above with respect to:
- Reading the instructions,
- Alignment of Positive (+) and Negative (-) metal contacts (battery vs charger), then, with the car ignition key in the off position,
- Connection of the Mini Power Inverter into the Cigarette Lighter Socket,
- Plugging of the Universal Battery Travel Charger into the Mini Power Inverter‘s 110/120 AC outlet, and
- Turning the ignition key to the Accessories/on position.
The Universal Battery Travel Charger should start charging the battery by now. Read the LED indicators (red, flashing red, and green). The first red LED indicates metal contacts; the second red flashing LED, the battery is being charged; and the green LED, the battery is fully charged.
Depending on the state of charge of the battery, and because of the Universal Battery Travel Charger‘s low output (DC 4.22 300mA), it may take a very long time – up to 10 hours in our experiment – to recharge a 50% discharged battery. When the battery is fully charged, unplug the charger.
Prolong cell phone battery charging (ignition key in accessory position) via Mini Power Inverter may deplete the car battery. Start the car, from time to time, to recharge the car battery. It’s best to charge the cell phone battery while driving.
Most of the latest cars come with built-in USB Power Ports and Power Inverters, which seemingly dispenses the need for extra Power Inverters and Universal USB Car/Vehicle Chargers. But by now you should know our philosophy with respect to foresight vs hindsight: it’s better to have extra gadgets as backups now rather than later, because you never know when the built-in accessories will break down. So, buy your Power Inverter and Universal USB Car Charger anyway!
Universal USB Car Chargers
Most Universal USB Car Chargers‘ output ranges from 5V DC 500 mA to 5V DC 2000 mA. The lower the amperage output (mA), the longer it takes to recharge the cell phone battery. Consequently, it is better to buy a Universal USB Car Charger with a 5V DC 2000 mA output than one with a 5V DC 500 mA. Still, a 5V DC 500 mA Adapter is better than none at all. The output may also be expressed in Amp instead of mA. For instance, you may read 5V .5A – 5V 2A in lieu of 5V 500 mA – 5V 2000 mA. Both mean the same thing.
Which Universal Battery Charger to Buy?
Vacillating as to which Universal Battery Charger to buy? Let the specs (see above table) be your guide. Based on that observation, it turns out that the Universal Battery Travel Charger is good, the Universal Battery Charger With LED Display better, and the Universal Battery Charger With LCD Display best (battery is recharged in less time). If you are a gadget freak, as we are, buy all three to experiment with. They are very inexpensive. Enjoy!
