Which Model Is Right for You
The JST524 is the straightforward power user pick — the only 20,000mAh model in the range and the only one with 45W output, which meaningfully cuts charge time on compatible phones and tablets. If you travel frequently or work long hours away from a plug, this is the one. At ₹2,999 it’s also excellent value for the capacity and wattage combination.
The JST530 is the design-forward option. Its slim profile, premium fabric finish, and MagSafe magnetic wireless charging make it the best fit for iPhone users who want cable-free charging without the bulk. The built-in foldable kickstand for hands-free viewing while charging is a practical bonus for video calls or streaming on the go.
The JST532 and JST534 both solve the same problem — cable clutter — but from slightly different angles. Both have dual built-in Type-C and Lightning cables plus Apple Watch charging support, eliminating the need to carry a separate cable bundle for iPhone, iPad, and Watch users. The JST534 steps it up with 22.5W fast charging and an invisible phone holder, making it the more complete package for Apple ecosystem users who want the kitchen-sink option at ₹2,199.
All four models include smart digital displays for real-time battery status, magnetic charging capability, and compact lightweight builds suited for daily carry. Safety protection — overcharge, overcurrent, and short circuit — is standard across the range.
