What's in My ₹3,000 On‑Call Kit (and Why I Carry It Everywhere)

Feb 19, 2026

A compact, practical on‑call kit you can assemble in a weekend — what to pack, why each item matters, and the real tradeoffs I learned on call in India.

Written by: Arjun Malhotra

If you’ve ever sprinted out of bed at 2 a.m. to fight a pager and found your home Wi‑Fi dead, you know the feeling: adrenaline, half-remembered runbook steps, and the conscious decision not to get out of pajamas to drive somewhere. For me, that sequence happened enough times that I stopped playing improv theatre and built a tiny, reliable kit I could grab in under 30 seconds.

I call it my on‑call kit. It fits in a small zip pouch and costs around ₹3,000 if you shop sensibly. It has saved me hours (and a lot of panic) more than once. Below’s what I carry, why each item matters, and the real downsides you should consider before doing the same.

What I pack (and why)

• A 10,000 mAh power bank (₹1,000–1,500)

  • Why: Phones, MiFi devices, and USB sticks die faster than you expect under continuous use. A 10,000 mAh bank is light, charges a phone once or twice, and can keep a small LTE hotspot running through a long incident.
  • Tradeoff: It adds weight and needs charging. I keep it topped up weekly.

• A basic LTE MiFi or USB dongle + a prepaid SIM (₹1,000–2,000 total)

  • Why: Home broadband or office VPN can be the single point of failure. A small MiFi gives you an independent path to the internet and a reproducible test environment. In India, look for carrier combos with decent night data or unlimited plan trials for Dev/Test.
  • Tradeoff: Mobile networks can be flaky in the same outage area; it’s insurance, not a silver bullet. Also, MiFi devices require occasional firmware checks.

• USB-C (or lightning) to Ethernet adapter (₹400–800) + 1m Cat6 cable

  • Why: When Wi‑Fi craps out but the ISP’s copper is alive, plugging into an ethernet-enabled wall port can restore enough connectivity to run diagnostics or push a rollback.
  • Tradeoff: Not every place has an exposed jack, and this is useless on flights. It’s a niche item that pays off rarely but hugely.

• A small multi‑cable (USB‑C, micro‑USB, lightning) and a 30‑cm USB‑A cable

  • Why: One cable that handles most devices beats rummaging for cords mid-incident. Short cables are better for portable power banks and cramped spaces.

• Two physical 2FA keys (YubiKey‑like) or an old phone with a dedicated authenticator app

  • Why: Some on-call tasks require privileged console access that’s bound to an MFA device. Keeping a hardware key or a dedicated offline phone minimizes the risk of losing MFA access when your primary device is unreachable.
  • Tradeoff: Hardware keys cost ~₹2k–5k. If you use keys, treat them like cash—losing one is a security incident.

• A laminated 1‑page runbook and emergency contacts

  • Why: Under stress you forget simple commands and passwords. A printed runbook with the fastest rollback and contact numbers saved offline is gold.
  • Tradeoff: Paper can be out of date. Update it monthly and store a digital snapshot in an accessible, encrypted place.

• A tiny USB stick with a rescue image (2–8 GB)

  • Why: Quick bootable tools for password resets, network diagnostics, or collecting logs. I keep one with a minimal Linux live image and a few scripts.
  • Tradeoff: Carrying sensitive scripts needs discipline—encrypt anything with credentials and treat the stick like a secure key.

• Pen, highlighter, and small notepad

  • Why: Phone notes are fine, but you sometimes need to jot network IPs, timestamps, or pager IDs quickly. Paper works offline and is easier to hand off during a shift change.

How I use it in practice

The kit lives on a small shelf near the front door. When a page comes, two steps: grab the pouch, check the battery light, and head for the nearest chair with signal. In 80% of cases where home broadband is flaky, the MiFi + power bank combo buys me a reliable connection within five minutes and the printed runbook tells me whether to roll back or scale a service.

I’ve also used the Ethernet adapter during office ISP outages—plug, authenticate through backup VPN, and run a quick healthcheck. Once I used the rescue USB to boot a recovery image and collect a kernel panic log from a workstation that wouldn’t boot otherwise. Real, small wins.

Real constraints and when not to bother

• Cost vs benefit: A full kit with YubiKeys and a MiFi can cross ₹4k–6k. For many individual contributors, the marginal value is high; for orgs with on-call teams and redundant infrastructure, a personal kit may be overkill.
• Security risk: Anything portable is a risk if lost. Encrypt USB sticks, separate personal vs. team MFA devices, and register hardware keys so they can be revoked quickly.
• Maintenance: Batteries die, SIMs get deactivated, and printed runbooks go stale. The kit is low effort to maintain if you schedule a weekly 5‑minute check, but it’s not “set and forget.”
• Not a replacement for good systems: If your architecture lacks redundancy, a kit is first‑aid. The real fix is better observability, runbooks, and prebuilt recovery automation.

How to assemble yours this weekend

1. Start tiny: buy a cheap 10,000 mAh power bank and a short multi‑cable (₹1,000 total). Test them for a week.
2. Add an LTE SIM (₹200–500) and either an old phone or a ₹1,200 MiFi. Verify connectivity from multiple rooms.
3. Add the runbook and a USB stick with a single rescue image when you feel comfortable.
4. Consider hardware MFA only if your team requires it; otherwise use a dedicated authenticator phone.

An on‑call kit isn’t a badge of toughness. It’s low-friction resilience: a small set of reliable tools that reduce cognitive load when things are messy. For me, carrying that pouch has turned a handful of 2 a.m. meltdowns into manageable, predictable work. You’ll still lose sleep sometimes—nothing fixes that—but you’ll lose far fewer mornings to panicked improvisation.
