For the following, I''m assuming that your project requires a DC power source and that the part of the circuit accepting that DC power source includes substantial input capacitance (for whatever reason you have.) And I''m assuming you''d like to see the sparks diminish when you connect the two, together. Insert a Series Resistor
All direct current circuits require DC power. This can come in form of a battery, a power supply, or an AC (alternating current) to DC converter. Computers (like laptops) that don''t use dedicated power supplies use ''AC adapters'' to convert AC power from a wall outlet into DC power. The adapter functions as the DC power source to the laptop.
Can I connect a capacitor to a power source directly?
It depends on the voltage ratings of the capacitor and the power supply - and how much current the power supply can deliver. If the the power supply voltage is higher than the rated voltage of the capacitor, then the capacitor will be damaged. Some capacitors will fail and short circuit when you exceed the voltage rating.
PULS currently offers two options for continuing to supply power to the load in an emergency: both electrochemical double-layer capacitors and lead-acid batteries can serve as energy storage in DC-UPS systems for industrial plants. Electrochemical double-layer capacitors, also known by trade names such as Ultracap, Supercap or …
A Super Capacitor and Battery Backup Power-Supply Design
Many applications today require low-power backup supplies based on supercapacitors and batteries, typically when an unexpected power disruption can cause problems. A well …
When to use supercapacitors in battery applications
A dc/dc converter may need to be added to provide the required voltage range. It is often the case that engineers who evaluate applications strictly from the standpoint of energy storage conclude that a …

One of the major problems that is to be solved in an electronic circuit design is the production of low voltage DC power supply from AC to power the circuit. [[wysiwyg_imageupload::]]The conventional method is the use of a step-down transformer to reduce the 230 V AC to a desired level of low voltage AC. The most suitable and low cost …
C1 typically occupies 5 to 6% of the internal space of a power supply, and so would increase the size of the power supply by around 50%, assuming the product height remains the same. 4. A 48V output AC-DC power supply and a wide range input non-isolated DC-DC Converter
Electronic Circuits: Linear/Analog. Louis E. Frenzel Jr., in Electronics Explained, 2010 Power Supplies. A power supply is, as its name implies, a source of power to an electronic circuit. Most electronic circuits operate from DC as they process AC or DC signals. The most common power supply is the one that gets its input from the standard AC wall outlet that …

This is then a design issue. Either the battery cannot provide enough power, the capacitor is too small, the load requires too much power, or a combination off. One should take into consideration the load, battery specifications and the capacitor simultaneously when designing the system.
In some cases (especially with marginal power supplies, long power cables etc.) adding extra capacitance on the GSM module, can help during the high-power GSM transmission bursts. A remote possibility is that you have a defective GSM module e.g. that large tantalum capacitor on the "stock photo" you gave, might be faulty.
