- SCP: 40W; UFCS: 33W; SVOOC: 45W
- VOOC 4.0: 30W (Requires a high-performance fast-charging cable)
- VOOC 1.0: 20W (requires a fast-charging cable); PE 1.1: 7.5W
- PE 2.0: 30W; QC 3+: 45W; QC 3.0: 36W; QC 2.0: 24W; AFC: 18W; FCP: 18W; SFCP: 18W; Multi-port output does not support fast charging
10. Type-C input and supported phone protocols: 5V/3.1A (standard input); PD 3.1: 65W (MAX); SCP: 40W; UFCS: 33W; SVOOC: 45W; VOOC 4.0: 30W (requires high-performance fast-charging cable); VOOC 1.0: 20W (requires fast-charging cable); AFC: 18W; FCP: 18W; Supports 5V charging and discharging simultaneously
11. Note: If the phonea??s proprietary protocol does not support fast charging (USB without fast charging), you can use PD charging (Type-C output). The PD open standard provides more stable output and higher power output.
12. Button functions: Single-press to display battery level; long-press to turn the LED light on or off; Double-click to turn off output; does not support low current or light control mode.
13. Compatible Batteries: 3.7V flat-top, unprotected ternary lithium 18650 batteries
14. Battery Configuration: Two in parallel, four in series (all batteries must be identical)
15. Note: Battery casings must not be damaged. Check the positive and negative terminals carefully and do not install them incorrectly, as this will cause a battery short circuit!
16. Valid battery pack voltage: 12.3Va??16.5V (note: the spring causes a voltage drop)
17. Minimum battery pack capacity requirement: The minimum actual capacity must not be less than 16,000 mAh. This is equivalent to at least 8 Grade A 2,000 mAh cells with identical voltage, internal resistance, and capacity. If this minimum requirement is not met, the battery case may fail to balance the cells properly and may be unable to fully charge or discharge them.
18. For the first three charges, it is recommended to start from 0%, charge to 100%, and then continue charging for at least 5 more hours to ensure the batteries are fully balanced!
19. Multiple protections, high reliability: 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
20. Note: We recommend using brand-new, high-rate, high-performance, high-capacity batteries. We do not recommend using batteries salvaged from disassembled devices, as they generally fail to meet rate requirements and are not durable. If you notice intermittent charginga??where the battery lasts only a few minutes or ten to twenty minutes, or cannot even charge a phone halfwaya??these are signs of poor battery performance. Please replace the battery immediately. Additionally, this product does not support modifications or soldering. We will not be responsible for after-sales service for product damage caused by incorrect installation or the use of non-compliant batteries.

Basic Knowledge About Fast Charging Protocols and Charging/Discharging (Please Read Carefully):
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, the device will charge at a standard rate. Standard charging typically delivers no more than 10W, or 5V/2A.
3. Fast-charging protocols are automatically matched between the phone and the chip; this cannot be manually controlled. Some phones support multiple protocols, and the phonea??s power management system selects the optimal fast-charging protocol based on the charging environment;
4. The current limit is 3.2A, and the voltage for phone charging protocols is generally within 10V; therefore, the maximum charging power for phones typically does not exceed 30W
5. The fast-charging protocols listed above represent the maximum power ratings specified by manufacturers. Actual charging performance varies; the current is controlled by the phonea??s own power management system and cannot be fixed, but may fluctuate within the specified power range.
6. Flash charging uses high current 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 when charging a phone, and the phonea??s battery level is below 80%, this is almost certainly caused by a problem with the 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 10 watts or more, this is almost certainly caused by a problem with the charging cable or the presence of high-internal-resistance, low-rate cells in the battery pack.
