Parameter
Compatible Batteries: 3.7V flat-top, unprotected ternary lithium 21700 batteries
Battery Configuration: 2 in parallel, 4 in series (all batteries must be identical)
Note: The battery casing must not be damaged. Carefully identify the positive and negative terminals and do not install them incorrectly, as this may cause a battery short circuit or even spontaneous combustion!
Effective Battery Pack Voltage: 12.5V–16.5V (Note: Voltage drop increases with more series connections)
Built-in input overvoltage and undervoltage protection; integrated output overcurrent, overvoltage, and short-circuit protection; built-in battery overcharge, over-discharge, and overcurrent protection; built-in IC over-temperature protection;
DC Port Output Specifications
DC1 Specifications: 5.5 × 2.1
DC2 Specifications: 5.5 × 2.5
Output Voltage: 3.3V–24V (multi-point voltage adjustment or continuous voltage adjustment available)
Note: Only the DC port supports voltage adjustment; it cannot be used simultaneously with the USB and Type-C ports. When multiple ports are in use simultaneously, the output is limited to 5V. The DC function is normally open and normally closed; once enabled, it remains active and cannot be automatically turned off. To turn off the circuit, switch back to USB mode
Output Power: 100W (MAX)
Output Current: 5A (MAX)
Button Controls: Press and hold the power button to enter DC mode; press the left or right function buttons once to adjust the voltage range; press and hold the left or right function buttons for continuous voltage adjustment
USB Output
5V/9V/12V/15V/20V/3A;
Supported Fast Charging Protocols: SCP; UFCS; PE1.1; PE2.0; AFC; QC3+; QC3.0; QC2.0; FCP; SFCP; SVOOC, and VOOC (requires a fast-charging cable with a recognition chip);
Note: Charging for most smartphones is limited to 10V/3A (30W); when multiple ports are in use simultaneously, only standard 5V charging is available;
Type-C Output
PD 100W 20V/5A (supports laptop charging recognition mode)
Recognized fast charging protocols: PD 3.1; PD 3.0; PD 2.0; 5V/9V/12V/15V/20V-3A;
Supported fast charging protocols: PD 3.0; PD 2.0; PPS; SCP; UFCS; PE 1.1; PE 2.0; AFC; QC3+; QC3.0; QC2.0; FCP; SFCP; SVOOC and VOOC (requires a fast-charging cable with a recognition chip);
PD charging cables without a recognition chip typically limit most smartphone charging to 10V/3A (30W); those with a high-voltage recognition chip generally support 9–20V (up to 45W);
Note: Simultaneous output to multiple ports does not support fast charging;
Type-C Input
Supported fast charging protocols: PD 100W 20V/5A (PD 3.1; PD 3.0; PD 2.0); 5V/9V/12V/15V/20V-3A;
PD 3.0; PD 2.0; PPS; SCP; UFCS; AFC; FCP; SVOOC and VOOC (requires a fast-charging cable with a recognition chip);
Supports 5V charging and discharging simultaneously;
Note: If your phone’s proprietary protocol does not support fast charging (USB without fast charging), you can use PD charging (Type-C output). The PD open standard supports over 90% of smartphones and provides higher and more stable output power.
Basic Knowledge of Fast Charging Protocols for Charging and Discharging
1. Fast charging is not a one-size-fits-all solution; it is merely a general term. Each smartphone manufacturer has its own proprietary protocol, and support for any one of these protocols enables fast charging;
2. If fast charging is not detected, only standard charging will occur. Standard charging for smartphones is typically limited to 10W or less, i.e., within 5V × 2A;
3. Fast-charging protocols are automatically matched between the phone and its chipset. While some phones support multiple protocols, the phone’s power management system selects the optimal fast-charging protocol based on the charging environment—this cannot be manually controlled;
4. If the charging cable lacks a high-voltage detection chip or is not a dedicated charging cable, the current is capped at 3A. Since the voltage for phone charging protocols is generally within 10V, the maximum power output for charging a phone typically does not exceed 30W.
5. The fast-charging protocols listed above represent the maximum power ratings specified by manufacturers. However, most smartphone manufacturers impose restrictions when non-original chargers are used, so the actual charging power is generally below 30W. Additionally, charging a smartphone is a variable process; the current is controlled by the phone’s own power management system and cannot be fixed—it can only fluctuate within the specified power range;
6. Flash charging involves high-current charging at 5V, which places extremely high demands on the charging cable; please use a dedicated flash-charging cable;
7. If the fast-charging current does not increase while the phone’s battery level is below 80%, the issue is almost certainly caused by a faulty charging cable or poor contact;
8. If the charging current for a battery pack is below 1A when the battery level is below 90%, and the charger has a power output of 10W or more, the issue is almost certainly caused by a faulty charging cable or the presence of high-internal-resistance, low-rate cells in the battery pack;
9. Since the current through the balancing resistors is extremely low, the balancing process will fail if there is a significant voltage difference between the cells. Please ensure that the actual voltage, capacity, rate, and internal resistance of all 8 cells are consistent; otherwise, one set of cells may discharge prematurely, causing the output to be interrupted;
